RNA contains ribose sugar instead of deoxyribose and uracil replaces thymine. Most RNA is single-stranded but tRNA forms a cloverleaf structure through complementary base pairing to carry amino acids to protein synthesis. DNA is found mainly in the nucleus while RNA exists in both the nucleus and cytoplasm, including messenger RNA which transports information from DNA to ribosomes, transfer RNA which carries amino acids, and ribosomal RNA which is a component of ribosomes for protein production.
RNA splicing, in molecular biology, is a form of RNA processing in which a newly made precursor messenger RNA transcript is transformed into a mature messenger RNA. During splicing, introns are removed and exons are joined together.
There are slides about DNA replication and types of DNA.
Here we study about different enzymes of replication and its process.Places of enzyme action also shown in the slides.Different proteins are also discussed.
RNA- A polymer of ribonucleotides, is a single stranded structure. There are three major types of RNA- m RNA,t RNA and r RNA. Besides that there are small nuclear,micro RNAs, small interfering and heterogeneous RNAs. Each of them has a specific structure and performs a specific function.

This slide presentaion contains information about Ribonucleic Acid. Its structure, types, components, bases and functions. Also, included in this presentation is the process of Protein Synthesis.
RNA, or ribonucleic acid, is a vital molecule in the field of molecular biology. It plays a crucial role in the flow of genetic information within cells, serving as a messenger that carries instructions from DNA to guide the synthesis of proteins. Unlike DNA, RNA is typically single-stranded and contains the nucleotide uracil instead of thymine.
There are several types of RNA, each with specific functions. Messenger RNA (mRNA) carries genetic information from the DNA in the cell nucleus to the ribosomes, where protein synthesis occurs. Transfer RNA (tRNA) delivers amino acids to the ribosomes, ensuring that the correct sequence of amino acids is assembled during protein synthesis. Ribosomal RNA (rRNA) is a structural component of ribosomes, which are the cellular machinery responsible for protein synthesis.
RNA is involved in various cellular processes beyond protein synthesis, such as gene regulation and the catalysis of biochemical reactions. Additionally, emerging research continues to unveil the diverse roles of RNA in cellular functions and disease mechanisms. The study of RNA has significant implications in understanding the fundamental processes of life and in the development of therapeutic interventions.
DNA and RNA are both stands of nucleotides but RNA can carry out for .pdfarbaazrabs
DNA and RNA are both stands of nucleotides but RNA can carry out for more functions than
DNA. How docs the structure of RNA differ from DNA? What additional activities/function can
RNA do that DNA cannot?
Solution
The structure of ribonucleic acid is single stranded in which thymine replaces uracil as
complimentary base and other adenine, guanine, cytosine are the nucleotides but
deoxyribonucleic acid is double stranded & duplex.
The additive activities can RNA performing are to undergo \"translation\" to code for proteins
the following are the other functions where as DNA cannot undergo translation directly to code
for proteins
Small nuclear ribonucleic acid (snRNA): It is also known as U-RNA as it contains many uridine
contents in its complex structure. This is composed of 150 nucleotides nearly to produce
spliceosomes and to act along with snRNP. This snRNA has a predominant role in splicing.
mRNA: It is produced by the transcription of DNA in the presence of RNA polymerase enzyme
and it has amino acid coding exons to code for specific proteins as per genetic code.
rRNA (ribosomal RNA): It has 50S and 30S ribosomal subunits which have aminoacyl site and
peptidyl site to carry out translation process during protein synthesis with mRNA.
tRNA (transfer RNA): It has clover leaf structure & common to all tRNA structure. It has
anticodon site to bind to the mRNA and to displace mRNA transcript from nuclear region onto
the rRNA for protein synthesis. It is considered as an adaptor molecule mainly consist of 76 to
90 ribonucleotides in length
piRNA:
Piwi-interacting RNAs (piRNA) are the small non-coding RNA molecules with 26 to 31
nucleotides that are expressed in many of the germ lines of eukaryotic animals. piRNAs interact
with piwi proteins to form RNA-protein complexes..
This presentation is about a type of nucleic acid which is called RNA. in this presentation we will discuss RNA. its types, its structure and Functions etc. Like and download my slide so i will upload more and more presentations for you peoples.
