What is different with retroviruses in reproduction is that they do not kill their hosts at first because they can still insert their own genome. This process is what is known the reverse transcription. This is done by different proteins.
Answer:
(A). Result in different amino acids to be read due to frame shifts
Explanation:
Insertion or deletion mutations (or Indel mutations) can be defined as mutations in DNA due to insertion (addition) or deletion of nucleotide bases in DNA.
These mutations lead to change in reading frames (sequence of codons), which leads to formation of protein having completely different amino acid sequence. Hence, these mutations are also cause frameshift mutations.
This is due due to triplet nature of genetic codes as insertion or deletion of one or more bases (but not three) would change change in codon sequence and mutated sequence can form a non-functional or truncated protein.
Thus, the correct answer is option (A).
