Genetic Mutations and Bioengineering

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one nucleotide is replaced with a different nucleotide in the DNA sequence.

What is selective breeding?

Back

Selective breeding is the process of choosing specific organisms with desirable traits to reproduce, enhancing those traits in future generations.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, shifting the reading frame of the codons.

Why are insertion and deletion mutations particularly harmful?

Back

Insertion and deletion mutations can change all subsequent codons, altering the entire amino acid sequence downstream from the mutation.

What is a substitution in the context of genetic mutations?

Back

A substitution is a type of mutation where a single amino acid in a protein is changed due to a change in a single nucleotide.

What are the potential effects of genetic mutations on protein function?

Back

Genetic mutations can lead to changes in protein structure and function, potentially resulting in loss of function, gain of function, or altered function.

What is the role of codons in protein synthesis?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids during protein synthesis.

What is the difference between a point mutation and a frameshift mutation?

Back

A point mutation involves a change in a single nucleotide, while a frameshift mutation involves the insertion or deletion of nucleotides, altering the reading frame.
