Question

During cell division, DNA undergoes replication. DNA is transcribed into mRNA and the genetic code is translated into a polypeptide sequence. Out of these three processes, which is most likely to be the site a deletion, frameshift, insertion missense, nonsense, point and silent mutation or alteration occurred? Explain why you have chosen this process.

Answer 1

Replication

Out of replication , transcription ( DNA to mRNA ) and translation (mRNA to proteins ) the Replication is most likely to be the site of deletion , framework, insertion missence , nonsense ,point and silent mutation or alteration

Point mutation : Mutation in the DNA where a single nucleotide base is deleted (deletion), inserted(insertion) or changed

Silent mutation : Mutation in the DNA that does not result in the change of the amino acid sequence of a protein

Missence : Mutation in the DNA that results in single amino acid change

Nonsense Mutation : Substitution mutation in the DNA that results in stop codon appearance in the place of a codon that codes an amino acid
