How are proteins modified after translation
WebPost-translational modification can occur at any step in the life cycle of a protein. For example, many proteins are modified shortly after translation is completed to mediate proper protein folding or stability or to direct the nascent protein to distinct cellular compartments (e.g., nucleus, membrane). Why is RNA splicing necessary? WebA: The translation is the process of protein synthesis. Q: Describe how cDNA is made. A: A cDNA or complementary DNA (deoxyribonucleic acid) is produced from ssRNAs …
