Question

1A. True or False?

A change in the amino acid sequence in a gene will always result in a change in the nucleotide sequence of a protein.

1B. Briefly explain/defend your answer.

Answer 1

A change in amino acid sequence in a gene will always result in a change in the nucleotide sequence of a protein. Troue. A change in DNA sequence can lead to change in amino acid sequence of the protein. It is also called as Mutation. Mutation is the process of change in structure of a gene, by any alteration of single base unit

Any type of insertion or deletion of one or move nucleotides can lead to frameshift mutation. The outcome will be complete alteration of amino acid Sequence of a prołein. This can occur during translation Consider an example that consists of three words representing three letter codon BIG BAD FLY HAD RED EYE When mutation eliminates 304 nucleotide in this case letter "G". Then; BIB ADF LYH ADR EDE YE Thus a change in a nucleotide changes every single codon in sequence and change in amino acid sequence of protein.
