What is a gene mutation?

Back

A gene mutation is a change in the nucleotide sequence of a gene, which can affect the function of the gene.

Front

Define mutation in the context of DNA.

Back

A mutation is any change to the sequences of bases in a DNA molecule.

Front

If an organism inherits a mutation from a parent, where is this mutation found?

Back

The mutation is found in all of the organism's body cells.

Front

Can a mutation acquired in a skin cell be passed on to offspring?

Back

No, mutations in somatic cells (like skin cells) cannot be passed on to children.

Front

What is a frameshift mutation?

Back

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

Front

What is the difference between a gene mutation and a chromosomal mutation?

Back

A gene mutation affects a specific gene, while a chromosomal mutation affects the structure or number of chromosomes.

Front

What are the possible effects of mutations on an organism?

Back

Mutations can be beneficial, harmful, or neutral, affecting an organism's traits and survival.

Front

What is a deletion mutation?

Back

A deletion mutation is a type of mutation where one or more nucleotides are removed from the DNA sequence.

Front

What is an insertion mutation?

Back

An insertion mutation is a type of mutation where one or more nucleotides are added to the DNA sequence.

Front

How can environmental factors lead to mutations?

Back

Environmental factors such as UV radiation, chemicals, and viruses can cause changes in the DNA sequence, leading to mutations.
