Biosensors are analytical devices that detect biological processes and convert them into electrical signals. They have two basic components - a biological component that interacts with the target analyte, and a physical component called a transducer that converts the biological response into a measurable signal. Leland Clark, considered the father of biosensors, invented the Clark Electrode for measuring oxygen in liquids. Examples of biosensors include glucose monitoring devices and pregnancy test kits. Biosensors have a wide range of applications from food analysis and drug development to medical diagnosis and environmental monitoring.

During DNA elongation, DNA polymerase adds complementary DNA nucleotides to the 3' end of a newly synthesized strand using the template strand as a guide. On the lagging strand, DNA polymerase can only synthesize DNA in the 5' to 3' direction, so Okazaki fragments are formed that later need to be joined together. In contrast, the leading strand is synthesized continuously because DNA polymerase can add nucleotides to the 3' end that is open for elongation as the replication fork moves along.

There are several mechanisms of DNA repair: direct reversal, excision repair, mismatch repair, and double-stranded break repair. DNA repair is crucial because it prevents unrepaired DNA damage from causing mutations that can lead to cancer.
DNA REPAIR MECHANISM AND THEIR TYPES.pptx
There are five major DNA repair pathways that cells use to repair different types of DNA damage: base excision repair, nucleotide excision repair, mismatch repair, homologous recombination, and non-homologous end joining. These pathways repair damage caused by mismatches during replication, removal of damaged bases, single-strand breaks, double-strand breaks, and DNA cross-links. Nucleotide excision repair removes a variety of lesions that cause distortions to the DNA structure by cleaving segments of DNA containing damage.
DNA STRUCTURE AND TYPES .pptx
DNA is a double-stranded molecule composed of nucleotides that contain nitrogenous bases, a deoxyribose sugar, and a phosphate group. The bases on one strand form hydrogen bonds with complementary bases on the other strand to form the sides of the DNA ladder. The structure of DNA was discovered by Watson and Crick who proposed a double helix model with the bases forming rungs and the sugar-phosphate backbones forming the sides. There are different conformations of DNA including A-DNA, B-DNA, and Z-DNA which differ in their structural features such as helical sense, base pair orientation, and distance between base pairs.
TOPIC- DIFFERENT TYPES OF RNA, THEIR SYNTHESIS AND STRUCTURE.pptx
There are three main types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA carries DNA's message to direct protein synthesis, is short-lived, and single-stranded. tRNA is small and stable, carrying amino acids to the ribosome. rRNA composes most of the ribosome's mass, ensuring proper alignment of mRNA, tRNA, and ribosomes during protein synthesis.
PROKARYOTS DNA REPLICATION.pptx
This document summarizes prokaryotic DNA replication. It describes prokaryotic replication as the process by which a circular, double-stranded DNA molecule in prokaryotic cells is copied to produce two identical molecules. The key steps are initiation at a single origin of replication, elongation of DNA strands by DNA polymerases, and termination resulting in two circular chromosomes. The replication occurs rapidly in the cytoplasm and requires enzymes including DNA polymerases I and III.
Lac Operon System(Catabolite Repression).pptx
The document describes the lac operon system in E. coli for lactose catabolism. It explains that when glucose is absent and lactose is present, allolactose acts as an inducer by binding to the lac repressor and allowing RNA polymerase to transcribe the lac genes encoding β-galactosidase and other proteins for lactose metabolism. However, when glucose is present, even if lactose is also present, transcription is repressed due to low cAMP levels inhibiting the CAP-cAMP complex from activating transcription.
DNA POLYMERASE.pptx
There are five different DNA dependent DNA polymerases in E. coli bacteria: DNA polymerase I, II, III, IV and V. DNA polymerase III is the primary enzyme involved in DNA replication, forming a high-speed, high-fidelity multiprotein complex. DNA polymerases IV and V are Y-family polymerases that replicate damaged DNA with lower fidelity than polymerase III. DNA polymerases I and II serve backup roles in DNA repair through their exonuclease activities when the template is damaged.
DNA POLYMERASE AND RNA POLYMERASE.pptx
DNA polymerase is an enzyme that reads existing DNA strands as templates and creates two new strands through phosphodiester bond formation. It was first discovered in E. coli by Arthur Kornberg. DNA polymerase has a structure resembling an open right hand with palm, finger, and thumb domains that each perform different functions in nucleotide recognition and binding. RNA polymerase is a multi-subunit enzyme responsible for copying DNA sequences into RNA during transcription from 5' to 3'. It contains alpha, beta, and sigma subunits that play various roles in binding to promoter regions and catalytic activity.
PROKARYOTIC DNA REPLICATION .pptx
Prokaryotic DNA replication begins at the origin of replication and proceeds bidirectionally. It involves three main steps: initiation, elongation, and termination. Initiation begins at the origin of replication site, where proteins bind and unwind the DNA. Elongation then uses DNA polymerase III to simultaneously synthesize the leading and lagging strands. Termination occurs when the replication forks from opposite directions meet at the termination site and halt, resolving issues through proteins like TUS and topoisomerases.
Prokaryotic DNA replication.pptx
Prokaryotic DNA replication begins at the origin of replication site where the replication fork is formed. DnaA and other proteins recognize the origin site and unwind the DNA double helix. RNA primers are synthesized which allows DNA polymerase III to begin bidirectional DNA synthesis of the leading and lagging strands. Okazaki fragments are formed and ligated on the lagging strand. Replication terminates when the replication forks meet at the termination site and the daughter chromosomes are separated.
DNA repair mechanism and their types.pptx
DNA repair is a collection of processes cells use to identify and correct damage to DNA. There are several types of DNA repair mechanisms, including direct repair, base excision repair, mismatch repair, recombination repair, and SOS repair. DNA repair has advantages of maintaining genetic integrity between generations and preserving individual health, but defects can lead to increased cancer risks and premature aging syndromes.
TOPIC NAME Structure of DNA and their Type.pptx
DNA has a double helix structure that resembles a twisted ladder. It is composed of nucleotides, each containing a sugar, phosphate group, and one of four nitrogen bases (A, T, C, or G). The bases on opposite strands bond together via hydrogen bonds between A-T and C-G to form the structure. Erwin Chargaff discovered that the amounts of A and T are equal, as are the amounts of C and G in any DNA sample. There are three types of DNA structures: A-DNA, B-DNA, and Z-DNA.
LAC OPERON SYSTEM.pptx
The document describes the lac operon system, which was the first operon described in 1961 and controls the catabolism of lactose in prokaryotes. The lac operon has 5 structural units - a promoter, operator, three structural genes (LacZ, LacY, LacA) that encode enzymes for lactose breakdown, CAP binding sites, and a regulatory gene. When lactose is absent, a repressor protein binds to the operator, preventing transcription of the structural genes. When lactose is present, it binds to the repressor and causes a conformational change that releases it from the operator, allowing transcription and the breakdown of lactose.
LAC OPERON 2.pptx
The lac operon is a cluster of three genes in prokaryotes that are involved in processing the sugar lactose. It consists of a promoter, operator, and structural genes. The lac operon is inducible, meaning it is only transcribed when lactose is present. Depending on whether lactose and glucose are present or absent, the lac operon will be either actively transcribed or transcriptionally inactive.
DNA STRUCTURE AND TYPES.pptx
DNA is a double-stranded molecule composed of nucleotides that contain nitrogenous bases, a deoxyribose sugar, and a phosphate group. The bases--cytosine, thymine, adenine, and guanine--form rungs of a twisted ladder structure, while the alternating sugar and phosphate molecules form the sides. Watson and Crick discovered that the bases pair up specifically through hydrogen bonds to form the DNA double helix, which contains the genetic information needed to build an organism. DNA can take on different secondary structures including A-DNA, B-DNA, and Z-DNA forms.
TOPIC-DNA repair mechanism and their types.pptx
DNA repair mechanisms are necessary to correct damage to DNA that could otherwise lead to mutations and cancer. There are several types of DNA repair mechanisms that address different types of damage, including base repair through excision, resynthesis and ligation of bases, nucleotide excision repair to address mismatches, and mismatch repair to fix errors. Double stranded breaks can be repaired through non-homologous end joining or homologous recombination repair.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
