Final answer:
A frameshift mutation occurs when one or more nucleotides are inserted or deleted from a gene, resulting in a change in the reading frame of the base sequence. The new DNA base sequence after the deletion of the fifth base in the given sequence is TAACTATGACGTCG. Frameshift mutations can have a significant impact on the protein product, altering the amino acid sequence and potentially affecting its function.
Step-by-step explanation:
A frameshift mutation is a type of mutation that occurs when one or more nucleotides are inserted or deleted from a gene, resulting in a change in the reading frame of the base sequence.
In the given sequence, the fifth base, C, is deleted due to the frameshift mutation. Therefore, the new DNA base sequence would be: TAACTATGACGTCG.
Frameshift mutations can have a dramatic effect on the protein product because they change all the codons that follow the mutation. This can lead to the production of an entirely different amino acid sequence and potentially disrupt the function of the resulting protein.
