Which is an example of a deletion mutation that results in a new protein?
a)cat - cga - tcc mutates to cac - tcg - atc - c
b)aat - cgg - cca mutates to aac - cgg - cca
c)aat - cgg - cca mutates to aat - cgg - aat - cca
d)cat - cga - tcc mutates to cat - tcc

The correct answer is-

D) CAT - CGA - TCC mutates to CAT - TCC.

Mutation can be described as permanent change in the genetic material ( DNA) of living organism. Deletion is a type of mutation, which results due to the loss of part of chromosome or loss of DNA sequence during the process of replication of DNA. Due to this, a new or truncated protein is produced when DNA undergoes transcription ( formation of mRNA from DNA) and translation ( formation of protein from mRNA).

In the given options of this question, option D) is an example of deletion mutation as the strand CAT - CGA - TCC shows the deletion of CGA and forms CAT - TCC, which will form new protein.

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.

i won't lie i don't know so go online and ask google thats what i do
