DNA contains the genetic instructions that make each species unique. It is found inside the cell nucleus, packaged into chromosomes. During cell division, DNA unwinds and replicates itself so that each new cell receives an identical copy of the genetic instructions. DNA is made up of nucleotides containing phosphate, sugar, and one of four nitrogen bases (adenine, cytosine, thymine, guanine) that bond together in a double helix structure to precisely transmit genetic information from parent to offspring.
A Dna And Amino-Acids Based Implementation Of Four-Square CipherIJERA Editor
The DNA cryptography is a new and very promising direction in cryptographic research. It is in the primitive
stage. DNA cryptography is shown to be very effective. Currently, several DNA computing algorithms are
proposed for many cryptography, cryptanalysis and steganography problems, and they are very powerful in
these areas. This paper discusses a significant modification of the old approach of using DNA and Amino Acids
based approach with Playfair Cipher to using the same approach with different encryption algorithm, i.e;
foursquare cipher to the core of the ciphering process. In this study, a binary form of data, such as plaintext
messages, or images are transformed into sequences of DNA nucleotides. Subsequently, these nucleotides pass
through a Foursquare encryption process based on amino-acids structure. The fundamental idea behind using
this type of encryption process is to enforce other conventional cryptographic algorithms which proved to be
broken, and also to open the door for applying the DNA and Amino Acids concepts to more conventional
cryptographic algorithms to enhance their security features.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

DNA replication
Read the following and answer the questions below.
We all know that elephants only give birth to little elephants, giraffes to giraffes, dogs to dogs and so on
for every type of living creature. But why is this so? The answer lies in a molecule called deoxyribonucleic acid
(DNA), which contains the biological instructions that make each species unique. DNA, along with the instructions
it contains, is passed from adult organisms to their offspring during reproduction.
DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and
because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This
packaged form of the DNA is called a chromosome. DNA spends a lot of time in its chromosome form. But during
cell division, DNA unwinds so it can be copied and the copies transferred to new cells. DNA also unwinds so that
its instructions can be used to make proteins and for other biological processes. Researchers refer to DNA found
in the cell's nucleus as nuclear DNA. An organism's complete set of nuclear DNA is called its genome. Besides the
DNA located in the nucleus, humans and other complex organisms also have a small amount of DNA in cell
structures known as mitochondria. Mitochondria generate the energy the cell needs to function properly. In
sexual reproduction, organisms inherit half of their nuclear DNA from the male parent and half from the female
parent. However, organisms inherit all of their mitochondrial DNA from the female parent. This occurs because
only egg cells, and not sperm cells, keep their mitochondria during fertilization.
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts:
a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides
are linked into chains, with the phosphate and sugar groups alternating. The four types of nitrogen bases found in
nucleotides are: adenine (A), , thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases
determines what biological instructions are contained in a strand of DNA. For example, the sequence ATCGTT
might instruct for blue eyes, while ATCGCT might instruct for brown. Each DNA sequence that contains
instructions to make a protein is known as a gene. The size of a gene may vary greatly, ranging from about 1,000
bases to 1 million bases in humans. The complete DNA instruction book, or genome, for a human contains about
3 billion bases and about 20,000 genes on 23 pairs of chromosomes
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out
these functions, DNA sequences must be converted into messages that can be used to produce proteins, which
are the complex molecules that do most of the work in our bodies.
DNA's instructions are used to make proteins in a two-step process. First, enzymes read the information in
a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid, or mRNA.
Next, the information contained in the mRNA molecule is translated into the "language" of amino acids, which are
the building blocks of proteins. This language tells the cell's protein-making machinery the precise order in which
to link the amino acids to produce a specific protein. This is a major task because there are 20 types of amino
acids, which can be placed in many different orders to form a wide variety of proteins.
2. Scientist use the term "double helix" to describe DNA's winding, two-stranded chemical structure. This
shape - which looks much like a twisted ladder - gives DNA the power to pass along biological instructions with
great precision.
To understand DNA's double helix from a chemical standpoint, picture the sides of the ladder as strands of
alternating sugar and phosphate groups - strands that run in opposite directions. Each "rung" of the ladder is
made up of two nitrogen bases, paired together by hydrogen bonds. Because of the highly specific nature of this
type of chemical pairing, base A always pairs with base T, and likewise C with G. So, if you know the sequence of
the bases on one strand of a DNA double helix, it is a simple matter to figure out the sequence of bases on the
other strand.
DNA's unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the
DNA helix splits down the middle and becomes two single strands. These single strands serve as templates for
building two new, double-stranded DNA molecules - each a replica of the original DNA molecule. In this process,
an A base is added wherever there is a T, a C where there is a G, and so on until all of the bases once again have
partners.
In addition, when proteins are being made, the double helix unwinds to allow a single strand of DNA to serve as a
template. This template strand is then transcribed into mRNA, which is a molecule that conveys vital instructions
to the cell's protein-making machinery.

3. DNA Base-Pairs Worksheet Name
DNA is made up of nucleotides. Each nucleotide is made up of a sugar, a phosphate, and a base. There are
four bases that can be in DNA nucleotides: adenine, cytosine, thymine, and guanine. Remember that
adenine and thymine are complementary and form pairs, and cytosine and guanine are complementary and
form pairs.
Part A: Below are half sections of DNA that has been split apart and is ready to copy itself. Write the
appropriate letter in the space provided to build the DNA’s complementary strand.
