What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism's genome.

Front

What are the types of mutations?

Back

The main types of mutations are substitution, insertion, deletion, and translocation.

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one base pair in the DNA sequence is replaced by another.

Front

What is an insertion mutation?

Back

An insertion mutation involves the addition of one or more nucleotide base pairs into a DNA sequence.

Front

What is a deletion mutation?

Back

A deletion mutation occurs when one or more nucleotide base pairs are removed from a DNA sequence.

Front

What is translocation in genetics?

Back

Translocation is a mutation where a segment of DNA is moved from one location to another within the genome.

Front

What is the effect of a stop codon in translation?

Back

A stop codon signals the termination of protein synthesis during translation.

Front

What is gel electrophoresis used for?

Back

Gel electrophoresis is used to separate DNA fragments based on their size.

Front

What is genetic engineering?

Back

Genetic engineering is the manipulation of an organism's genetic material to achieve desired traits.

Front

What is PCR (Polymerase Chain Reaction)?

Back

PCR is a technique used to amplify specific DNA sequences, making millions of copies of a particular segment.
