A mutation causing an addition or a deletion of one base pair resulted in the production of a nonfunctional mutant protein. The sequences of the normal and mutant proteins are given below. Normal: Met - Tyr - His - Glu - Val Mutant: Met - Phe - Thr - Lys - Cys - Lys - Trp - Arg - .....
Was this mutation cause by an insertion or a deletion?

Respuesta :

Answer:

Explanation:

The mutation was caused as a result of deletion of one letter of the codon A from tyrosine leading a shift in the reading frame.

Normal is

Normal - Met - Tyr -His- Glu- Val

Aug- Uac- Cac - Gaa -Gug

When a is removed from Tyrosine codon we have a shift in the reading frame to form a mutant with a new codon and protein.

Mutant - Met- Phe - Thr - Lys -Cys

Aug- Ucc- Acg - Aag -Ugu

Mutation is a sudden change in the genie of an organism that can be heritage by offspring from their parent.
