tRNAs are 60-95 nucleotides long with modified nucleotides. They have an anticodon loop and 3' CCA acceptor stem. Aminoacyl-tRNA synthetases couple amino acids to the 3' end of corresponding tRNAs. The tRNA anticodon then pairs with mRNA codons during translation. Errors can cause wrong amino acids in proteins.
It is the process of synthesis of protein by encoding information on mRNA.
Protein synthesis requires mRNA, tRNA, aminoacids, ribosome and enzyme aminoacyl tRNA synthase

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
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.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:

3. Structures of tRNAs (a) tRNAs are 60~95 nucleotides long. (b) Contain several modified nucleotides. (c) The anticodon loop and the 3’ CCA of the acceptor stem. AARS 5SrRNA Amino Acid(COOH)
4. Two-step decoding process for translating nucleic acid sequences in mRNA into amino acid sequences in proteins The first step is mediated by the aminoacyl-tRNA synthetase, which couples a particular amino acid to its corresponding tRNA molecule at the 3’ end of tRNA (via a high-energy ester linkage with the 2’ or 3’-hydroxyl group of the terminal adenosine). The anticodon of the aminoacyl-tRNA forms base pairs with the appropriate codon on the mRNA during the second step. An error in either step would cause the wrong amino acid to be incorporated into a protein chain.
5. (b) Aminoacyl-AMP + tRNA aminoacyl-tRNA + AMP (a) ATP + amino acid aminoacyl-AMP + PPi
9. Protein Factors Required for Initiation of Translation in Bacterial Cells Bacterial Factor Function IF-1 Help IF3 IF-2 Transport f-Met-tRNA to P site IF-3 Divids 2 subunit of ribosome & help mRNA to join ribosom
10. In eukaryotic mRNAs the 5’ cap structure help define the start codon. The 40S subunit binds to the cap structure and then locates the first AUG codon 3’ to the cap structure as the translation start site. Shine-Delgarno sequence Start signals for the initiation of protein synthesis in (A) prokaryotes and (B) eukaryotes
11. In procaryotes, there can be multiple ribosome-binding sites ( Shine-Delgarno sequences ) in the interior of an mRNA chain, each resulting in the synthesis of a different protein. A comparison of the structures of procaryotic and eucaryotic messenger RNA molecules
14. Factors Function Elongation Factors EF-Tu-(GTP) Binds aminoacyl-tRNA to A-site ribosom EF-Ts Displaces GDP from EF-Tu EF-G(GTP) ترانس لوکاز جابجایی ریبوزوم و mRNA به اندازه یک کدون
15. The second aminoacyl-tRNA enters the A site of the ribosome bound to EF-Tu (shown here as Tu), which also contains GTP. Binding of the second aminoacyl-tRNA to the A site is accompanied by hydrolysis of the GTP to GDP and P i and release of the EF-Tu•GDP complex from the ribosome. The bound GDP is released when the EF-Tu•GDP complex binds to EF-Ts, and EF-Ts is subsequently released when another molecule of GTP binds to EF-Tu. This recycles EF-Tu and makes it available to repeat the cycle.
16. Second step in elongation: formation of the first peptide bond Peptidyl transferase
17. The ribosome moves one codon toward the 3’ end of mRNA, using energy provided by hydrolysis of GTP bound to EF-G (translocase). The dipeptidyl-tRNA is now entirely in the P site, leaving the A site open for the incoming (third) aminoacyl-tRNA. The uncharged tRNA dissociates from the E site, and the elongation cycle begins again.
18. The soluble Protein Factors of E. coli Protein Synthesis Factor Mass (kD) Function Release Factors RF-1 Recognizes UAA and UAG Stop codons RF-2 Recognizes UAA and UGA Stop codons RF-3 همکاری و کمک به فاکتورهای RF1 و RF2
19. Termination of protein synthesis in bacteria Termination occurs in response to a termination codon in the A site. First, a release factor (RF 1 or RF 2 depending on which termination codon is present) binds to the A site . This leads to hydrolysis of the ester linkage between the nascent polypeptide and the tRNA in the P site and release of the completed polypetide. Finally, the mRNA, deacylated tRNA, and release factor leave the ribosome, and the ribosome dissociates into its 30S and 50S subunits.
20. Schematic drawing showing how a series of ribosomes can simultaneously translate the same eukaryotic mRNA molecule, which is in circular form stabilized by interactions between proteins bound at the 3’ and 5’ ends. The 5’ cap and 3’ poly(A) tail have been shown to synergistically enhance translation initiation. They may do so through facilitating ribosome recapture on circularized mRNAs.
