What is a mutation?

Back

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

Front

What are the two main types of mutations?

Back

The two main types of mutations are gene mutations (affecting a single gene) and chromosomal mutations (affecting whole chromosomes).

Front

What is genetic diversity?

Back

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are added or deleted from the DNA sequence, altering the reading frame.

Front

What is a silent mutation?

Back

A silent mutation is a change in the DNA sequence that does not affect the amino acid sequence of the resulting protein.

Front

Can mutations be beneficial?

Back

Yes, mutations can be beneficial as they can increase genetic diversity and enhance survival.

Front

What are genetic disorders?

Back

Genetic disorders are diseases caused by abnormalities in an individual's DNA.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the difference between substitution and frameshift mutations?

Back

Substitution mutations replace one nucleotide with another, while frameshift mutations involve the addition or deletion of nucleotides.
