Mutations

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is a deletion mutation?

Back

A deletion mutation occurs when a base pair is missing from the DNA strand.

Front

What is an insertion mutation?

Back

An insertion mutation occurs when a base pair is added to the DNA strand.

Front

What is a substitution mutation?

Back

A substitution mutation occurs when a base pair is replaced with a different base pair.

Front

What is a frameshift mutation?

Back

A frameshift mutation is caused by insertions or deletions that change the reading frame of the genetic code.

Front

What are the effects of mutations on proteins?

Back

Mutations can lead to changes in protein structure and function, potentially resulting in diseases or altered traits.

Front

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

Back

A point mutation involves a change in a single base pair, while a frameshift mutation involves insertions or deletions that shift the reading frame.

Front

What is the role of DNA in mutations?

Back

DNA carries the genetic information, and mutations are changes in this genetic code.

Front

How can mutations be beneficial?

Back

Some mutations can provide advantages, such as increased resistance to diseases or improved survival in changing environments.

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 protein.
