Answer #1

Ans- ubiquitination of proteins- mechanism of protein degradation,

ubiquitination of proteins involves the attaching of multi ubiquitin molecules on protein to formed a multiubiquitin chain. these polyubiquitin proteins are recognized and degraded by a large multisubunit complex known as the proteasome. this process regulates the stability and functional activity of proteins and this process is not regulated by RNAi or RNA interference.

so option 4 ubiquitination of proteins is the right answer

inhibition of translation, transcription silencing, degradation of mRNA, and cleavage of mRNA all are regulate the expression of genes. these all process are regulated by RNAi

    As indicated in the image below, miRNAs usually have imperfect base pairing with their target mRNAs, which leads to translational inhibition (the RISC complex is large, and won't let ribosomes through). On the other hand, siRNAs produced from longer double stranded RNA molecules (e.g. viruses), usually show perfect binding to their target mRNAs, which leads to mRNA degradation by the RISC complex. In 100 words or fewer explain why these two types of inhibitory ncRNAs differ in their mode of...

    Which of the following mechanisms to regulate gene expression are observed in eukaryotes, but are not generally observed in prokaryotes? Choose all that apply. Genes are grouped into operons, which allows transcriptional regulation to turn them all on together. RNA silencing selectively targets mRNA and destroys it to prevent further translation. Proteins can be activated or deactivated as a form of post-translational regulation. Epigenetic regulation can open or condense sectiosn of a chromosome, regulating which genes are transcribed. Regulatory proteins...
