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 5â€™ 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
