The document provides information about protein synthesis, including:
1. Protein synthesis involves transcription of DNA into mRNA in the nucleus, and translation of mRNA into proteins at ribosomes in the cytoplasm.
2. Key molecules involved include DNA, mRNA, tRNA, ribosomes, and amino acids. DNA contains the genetic code. mRNA carries the code to the ribosomes. tRNA brings amino acids and pairs with mRNA codons.
3. Transcription and translation involve initiation, elongation, and termination steps. During transcription, RNA polymerase copies DNA onto mRNA. During translation, ribosomes read mRNA and link amino acids using tRNA.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
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.

9. Introduction
Protein synthesis is the
manufacture/synthesis of proteins.
Occurs in the nucleus and cytoplasm.
The genetic codes for specific proteins are
located on the DNA, e.g. codes for keratin,
collagen, Hb, polymerase, amylase, pepsin etc.
10. Introduction Continued
The triplet genetic codes on DNA are
called codons. This is a sequence of
three DNA bases.
The site for protein synthesis occurs on
the ribosomes (rRNA and protein) in the
cytoplasm.
11. Protein synthesis:
divided into 2 processes:
(A) Transcription: copying the codons
for a protein from a segment of the
DNA strand to make mRNA (messenger
RNA); requires 2 enzymes (helicase,
RNA polymerase).
Includes steps of initiation, elongation
and termination.
12. Second Process
(B) Translation: translate the sequence
of codons for the protein on the mRNA
to build a protein at the ribosome; tRNA
assists in this process.
Includes steps of initiation, elongation
and termination.
13.
14.
15.
16. B7– Roles of the Molecules
Involved in Protein
Synthesis
(a) DNA
Contains the information/genetic
code/triplet codes/codons for the
synthesis of proteins, e.g. TCG, ATG,
ATT.
Provides a template for mRNA to be
produced.
20. (b) mRNA
Carries the coded message from the
nucleus to the cytoplasm, e.g. codons
UAA, CGC, AGU
Sets the order of amino acids for
protein synthesis by the sequence of
codons. (Codon = 3 bases/ nucleotides in
a DNA or RNA sequence which specify a
single amino acid.)
21.
22. (c) Ribosomes
Provides a site for mRNA and tRNA to
join together by complementary base
pairing.
Site for protein synthesis (i.e.
translation) where it translates mRNA
and allows amino acids to bond (peptide
bond).
23. Note:
rRNA & protein make up the small and
large subunits of ribosomes. The small
subunit contains the binding site for
mRNA and the large subunit contains 2
binding sites for tRNA ~ amino acid and
a dehydration synthesis site!
26. (d) tRNA
Carries the specific
amino acid to the
ribosome where its
anticodon
complementary
base pairs with the
mRNA codon, e.g.
mRNA codon- UUA;
anticodon- AAU.
27.
28.
29.
30. (e) Amino acids
These are the monomers of proteins and
are picked up by tRNA in the cytoplasm,
i.e. tRNA~ amino acids.
31. Note:
mRNA Codon Table (see below) tells what 3
bases on mRNA code for each amino acid (64
combinations of 3 bases)
Methionine (AUG) on mRNA is called the
‘START codon’ because it triggers the linking
of amino acids
UAA, UGA, & UAG on mRNA signal
ribosomes to stop linking amino acids
together
42. Here we go…..
(a) DNA containing genetic code for
protein is in triplet codes.
(b) Initiation: RNA polymerase initiates
transcription by locating and binding to
the beginning of a gene/code (i.e. the
promoter region).
43. (c) Elongation: -Helicase unwinds, unzips DNA,
breaks H-bonds and provides a template for
mRNA formation.
RNA polymerase travels down the template
and complementary base pairs RNA
nucleotides with DNA codons forming a
mRNA,
e.g. DNA – CAT; mRNA – GUA.
RNA polymerase joins adjacent
nucleotides to mRNA, forming the S-P-S
backbone.
44. (d) Termination: -RNA polymerase reaches
termination sequence at end of
gene/code and STOPS mRNA synthesis.
RNA polymerase releases the mRNA and
detaches from the DNA.
mRNA exits nucleus through its pores
and enters the cytoplasm; DNA rejoins.
45. Note:
mRNA carries a sequence of codons
(linear order of three RNA bases
complementary to DNA triplet code) to
the ribosome…
One is a “STOP” codon, e.g. UAA, UAG
and UGA and a “START” codon, e.g. AUG
(Methionine).
46. 2. Translation (involves steps of
initiation, elongation and termination)
Location: cytoplasm at the ribosome
Product: protein/polypeptide
47.
48.
49. Translation
(a) tRNAs in the cytoplasm attach the correct
amino acid to one end (aided by enzymes).
(b) Initiation: tRNA~methionine binds to small
subunit and this binds to the mRNA. tRNA
anticodon (UAC) complementary pairs with
mRNA “ START” codon (AUG). Large subunit
binds to the small subunit assembling a
ribosome.
50. Translation continued
(c) Elongation: -Another tRNA (i.e.
tRNA~amino acid) with its anticodon
complementary base pairs with mRNA
codon on the ribosome. (It has 2 binding
sites for incoming tRNA~aa)
Ribosomes move along one codon to
receive the next incoming tRNA~aa.
51. Amino acid undergoes dehydration
synthesis and forms a peptide bond.
“Empty” or outgoing tRNA will bond with
another amino acid in the cytoplasm, i.e.
tRNA~aa.
52. (d) Termination: Synthesis of polypeptide
until a “STOP” codon on mRNA (UAA,
UAG, UGA).
Termination of protein synthesis and the
polypeptide chain and mRNA are
released from the ribosome.
Ribosome subunits separate.
53. Ribosomes can synthesize 5-15 peptide
bonds/sec!
Most proteins are 100-200 aa long &
takes less than a minute to be
synthesized!

59. B7– Problems Using the “Table
of mRNA codons”
Use the following table to answer
questions 1 – 7.
Note: most of the amino acids are coded
with 2, 3 or even 4 different codons. Of
these 64 codons, 61 are used to program
the 20 amino acids. Three of the 64
codons are used as signals to start or
stop the program.
64. Ok Let’s Try it Out!
1.) What are the RNA triplet codes for
Lysine? Leucine?
using the mRNA table, the codons for
Lysine are AAA or AAG.
using the mRNA table, the codons for
Leucine are CUU, CUC, CUA, CUG, UUA
and UUG.
65. 2.) What is the DNA triplet code for
Tryptophan?
mRNA = UGG (from table)
DNA = ACC.
3.) What are the mRNA triplet codons
for “STOP”?
using the mRNA table, the codons
are UAA, UAG and UGA.
66. 4.) The anticodon on a tRNA is GCU.
Determine the name of the amino acid
and its triplet codon.
tRNA anticodon GCU would
complementary base pair with mRNA
CGA at the ribosome.
using the table, the amino acid code for
CGA is Arginine.
67. 5.) DNA contains the following genetic
code: TACAAGATT. Determine the
amino acid sequence.
DNA = TAC|AAG|ATT
mRNA = AUG|UUC|UAA
= methionine-phenylalanine-stop
(from table).
