What does post translational control refer to?
Post-translational control can be defined as the mechanisms by which protein structure can be altered after translation. Proteins are polymers of amino acids, and there are twenty different amino acids. Both the order and identity of these amino acids are important for the role that the protein plays in the cell.
What is involved in post transcriptional control quizlet?
What is involved in post transcriptional control? Control of RNA splicing, control of RNA shuttling, and control of RNA stability.
Which of the following applies to post translational control?
The description that best applies to post-translational control is: regulation of gene expression after translation.
What is post translational modification quizlet?
last step in protein synthesis in which newly synthesized protein is chemically modified.
Where does post translational control occur?
Post-transcriptional control can occur at any stage after transcription, including RNA splicing, nuclear shuttling, and RNA stability. Once RNA is transcribed, it must be processed to create a mature RNA that is ready to be translated. This involves the removal of introns that do not code for protein.
What is translational control of protein synthesis?
Translational regulation refers to the control of the levels of protein synthesized from its mRNA. This regulation is vastly important to the cellular response to stressors, growth cues, and differentiation.
Which of the following are involved in post-transcriptional control?
Which of the following are involved in post-transcriptional control? Answer d. All of the above (control of RNA splicing, RNA shuttling, and RNA stability) are involved in post-transcriptional control.
What is a type of post-transcriptional regulation of gene expression quizlet?
STUDY. RNA editing. After transcription, sequence of mRNA is altered, i.e. deletions, insertions, and base changes; editing enzymes recognize specific RNA sequences/ structures. apoB gene.
Which of the following is involved in post translational control of gene expression?
Answer d. All of the above (control of RNA splicing, RNA shuttling, and RNA stability) are involved in post-transcriptional control.
What is an example of a post translational modification of a protein quizlet?
Protein ubiquitination is a common post translational modification in eukaryotes. Ubiquitination is reversible – ubiquitin ligases add ubiquitin, deubiquitinating enzymes remove ubiquitin.
What is the process of post translational modification?
Posttranslational modifications (PTMs) are covalent processing events that change the properties of a protein by proteolytic cleavage and adding a modifying group, such as acetyl, phosphoryl, glycosyl and methyl, to one or more amino acids (1).
Which of the following is are involved in post-transcriptional control?
