a) Three nucleotides are inserted into a protein-encoding gene.The insertion occurs such that the mRNA transcript has anadditional 3 bases (NOT a stop) right next to the stop codon (onthe 5’ side). Which of the following will be the result?
b) Which of the following are consequences of encoding eachamino acid using 3 nucleotides in the Genetic Code? (mre thanone)
A. There are three different reading frames in a single-strandedmRNA | |
B. tRNA anticodons contain 3 nucleotides | |
C. There are three types of substitutions in protein codingregions (silent, missense, nonsense) | |
D. Amino acids can be encoded by more than one codon | |
E. There are three different stop codons | |
F. Insertion/deletion of non-multiples of 3 bases in ORFscreates a frameshift |
