- Why is selenocysteine called the 21st amino acid when there are many more amino acids found than the 20 basic ones coded for by the genetic code?What is the unique feature of ribozyme function? Give two examples.If a prokaryotic gene coding region is 42 nucleotides long, beginning with a start codon and ending with a stop codon, how many amino acids will it have?
- How many proteins are there in a typical eukaryotic (nu- cleated) cell?Lactose permease, a protein of E. coli, is composed of a single polypeptide that is 417 amino acids in length. By convention, the amino acids within a polypeptide are numbered from the aminoterminus to the carboxyl-terminus. Are the following questions about lactose permease true or false? A. Because the 64th amino acid is glycine and the 68th amino acid is aspartic acid, the codon for glycine, 64, is closer to the 3′ end of the mRNA than the codon for aspartic acid, 68. B. The mRNA that encodes lactose permease must be greater than 1241 nucleotides in length.what role do introns play in the process of translation and how are prokaryotes able to go through this process without this step?
