Answer:

Given the sequence of bases of the RNA GGAUUC, the possible mutations would be:

a. Substitution: GGAUUC → GGAAUC

b. Insertion: GGAUUC → GGACCUUC

c. Deletion: GGAUUC → GG_UC

Explanation:

The fragment observed is recognized as RNA, due to the presence of uracil (U). The mutations observed in this fragment are derived from a mutated DNA molecule, which was transcribed into mRNA

  • Substitution is a molecular mutation that occurs when one nitrogenous base is changed to another in the DNA sequence.                              GGAUUC → GGAAUC   Mutated DNA: CCTTAG
  • Insertion occurs when entire bases or segments are added to the original genetic material, resulting in a longer molecule.                                 GGAUUC → GGACCUUC     Mutated DNA: CCTGGAAG
  • Deletion is a type of mutation where genetic material is lost, which can be nitrogenous bases or segments of the molecule.                                GGAUUC → GG_UC     Mutated DNA: CC_AG

Each of these mutations can have an effect on protein synthesis, affecting the structure or function of the final protein.
