Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

12.1 Identifying the Substance of Genes
LessonObjectives
Summarize the process of bacterial transformation.
Describe the role of bacteriophages in identifying genetic material.
Identify the role of DNA in heredity.
LessonSummary
Bacterial Transformation In 1928, Frederick Griffith found that some chemical factor from heat-
killed bacteria of one strain could change the inherited characteristics of another strain.
He called the process transformation because one type of bacteria (a harmless form) had been changed
permanently into another (a disease-carrying form).
Because the ability to cause disease was inherited by the offspring of the transformed bacteria, he concluded
that the transforming factor had to be a gene.
In 1944, Oswald Avery tested the transforming ability of many substances. Only DNA caused transformation.
By observing bacterial transformation, Avery and other scientists discovered that the nucleic acid DNA stores
and transmits genetic information from one generation of bacteria to the next.
Bacterial Viruses A bacteriophage is a kind of virus that infects bacteria. When a bacteriophage
enters a bacterium, it attaches to the surface of the bacterial cell and injects its genetic material into it.
In 1952, Alfred Hershey and Martha Chase used radioactive tracers to label proteins and DNA in
bacteriophages.
Only the DNA from the bacteriophage showed up in the infected bacterial cell.
Hershey and Chase concluded that the genetic material of the bacteriophage was DNA.
Their work confirmed Avery’s results, convincing many scientists that DNA was the genetic material found
in genes—not just in viruses and bacteria, but in all living cells.
The Role of DNA The DNA that makes up genes must be capable of storing, copying, and transmitting the
genetic information in a cell.
Bacterial Transformation
1. What happened when Griffith injected mice with the pneumonia-causing strain of bacteria that had been
heat-killed?
The mouse was not affected and lived.
2. What happened when Griffith injected mice with a mixture of heat-killed, pneumonia-causing bacteria and
live bacteria of the harmless type?
The mouse died of Pneumonia
3. What was the purpose of Oswald Avery’s experiments?
Oswald wanted to determine which molecules in the heat-killed bacteria was the most
important for transformation.
4. What experiments did Avery do?
Avery extracted a mixture of various molecules from the heat-killed bacteria that was
treated with enzymes.
5. What did Avery conclude?
Avery concluded that DNA was the transforming molecule.
2. Bacterial Viruses
3. Fill in the blanks to summarize the experiments of Hershey and Chase. (Note: The circles represent

3. What did Hershey and Chase conclude? Why?
Hershey and Chase concluded that the genetic material of the bacteriophage was DNA,
not protein.
4. How did Hershey and Chase confirm Avery’s results?
Hershaey and Chase convinced scientist that DNA was the genetic material found in
Genes, not just in viruses and bacteria but in living cells.

4. Lesson Summary
The Components of DNA DNA is a nucleic acid made up of nucleotides joined into long strands or
chains by covalent bonds. Nucleotides may be joined in any order.
A DNA nucleotide is a unit made of a nitrogenous base, a 5-carbon sugar called deoxyribose, and a
phosphate group.
DNA has four kinds of nitrogenous bases: adenine, guanine, cytosine, and thymine.
Solving the Structure of DNA
Erwin Chargaff showed that the percentages of adenine and thymine are almost always equal in DNA. The
percentages of guanine and cytosine are also almost equal.
Rosalind Franklin’s X-ray diffraction studies revealed the double-helix structure of DNA.
James Watson and Francis Crick built a model that explained the structure of DNA.
The Double-Helix Model The double-helix model explains Chargaff’s rule of base pairing and how the
two strands of DNA are held together. The model showed the following:
The two strands in the double helix run in opposite directions, with the nitrogenous bases in the center.
Each strand carries a sequence of nucleotides, arranged almost like the letters in a fourletter alphabet for
recording genetic information.
Hydrogen bonds hold the strands together. The bonds are easily broken allowing DNA strands to separate.
Hydrogen bonds form only between certain base pairs–adenine with thymine, and cytosine with guanine.
This is called base pairing.
The Components of DNA
For Questions 1–5, complete each statement by writing in the correct word or words.
1. The building blocks of DNA are nucleotides.
2. Nucleotides in DNA are made of three basic components: a sugar called deoxyribose ,a , phosphate and a

12.3 DNA Replication
LessonObjectives
Summarize the events of DNA replication.
Compare DNA replication in prokaryotes with that of eukaryotes.
LessonSummary
Copying the Code Each strand of the double helix has all the information needed to reconstruct the other
half by the mechanism of base pairing. Because each strand can be used to make the other strand, the strands are
said to be complementary. DNA copies itself through the process of replication:
The two strands of the double helix unzip, forming replication forks.
New bases are added, following the rules of base pairing (A with T and G with C).
Each new DNA molecule has one original strand and one new strand.
DNA polymerase is an enzyme that joins individual nucleotides to produce a new strand of DNA.
During replication, DNA may be lost from the tips of chromosomes, which are called telomeres.
Replication in Living Cells The cells of most prokaryotes have a single, circular DNA molecule in the
cytoplasm. Eukaryotic cells have much more DNA. Nearly all of it is contained in chromosomes, which are in
the nucleus.
Replication in most prokaryotic cells starts from a single point and proceeds in two directions until the entire
chromosome is copied.
In eukaryotic cells, replication may begin at dozens or even hundreds of places on the DNA molecule,
proceeding in both directions until each chromosome is completely copied.

6. Copying the Code
1. Why are the strands of a DNA molecule said to be complementary?
Strands of DNA are said to be complementary because they pair up with one another,
2. What is the first step in eukaryotic DNA replication?
First the Hydrogen bonds between base pairs unwind into two strands
3. If the base sequence on a separated DNA strand is CGTAGG, what will the base sequence on its
complementary strand be?
GCATCC
4. What enzyme joins individual nucleotides to produce the new strand of DNA?
Polymerase enzymes__ ________________________________________________
5. What enzyme makes it less likely that DNA will be lost from telomeres during replication?
Telomeres enzymes make it less likely that DNA will be lost.
6. How does this enzyme work?
It helps prevent the genes from being damaged and lost
7. What is a replication fork?
Replication forks are where the double –stranded DNA molecule splits into 2 single strands
8. Does DNA replication take place in the same direction along both strands of the DNA molecule that is
being replicated? Explain your answer. (Hint: Look at the illustration of DNA replication in your
textbook.)
It does not because replication occurs in the DNA molecule on both ends of the replication
fork at the same time in different direction.
Replication in Living Cells
