Which of the following is a way that protein function can be modified AFTER translation? Select one: a. gene duplication b. gene rearrangement c. protein cleavage d. exon shuffling e. transcription regulation
Homework Answers
Answer (c) protein cleaving
Post translational modification is the chemical modification of protein during or after the synthesis of protein.There are so many other ways through which protein function can be modified like methylation,phosphorylation,ubiquitination,lipidation,nytrocylation,proteolysis etc.proteolysis is the cleavage of peptide bond by proteases.Breakdown of protein into smaller polypeptide in the presence of proteases.

1.) Which of the following is not a mechanism to cause exon shuffling? a.) Pseudo-homologous centromere walking b.) Illegitimate recombination c.) Crossover events d.) Transposon emigration e.) All of these are exon-shuffling mechanisms - 2.) Early estimates of the number of protein-coding genes was over 100,000 genes. Why was this number so high? a.) The area of the genome that was analyzed had a high density of genes (gene-rich) and so it inflated the estimated number of genes b.) The...
