Mutation

What are mutations?

Changes in the genetic makeup of a cell (DNA sequence).

What causes mutations?

Mistakes during DNA replication and environmental factors (mutagens like radiation, chemicals).

What are chromosomal mutations?

Mutations that affect entire chromosomes.

What is deletion in chromosomal mutations?

Loss of part of a chromosome.

What is duplication in chromosomal mutations?

Extra copy of part of a chromosome.

What is inversion in chromosomal mutations?

Segment of chromosome flips.

What is translocation in chromosomal mutations?

Part of one chromosome moves to another.

What are gene mutations (point mutations)?

Changes in a single gene.

What are substitutions in gene mutations?

One nucleotide base pair is replaced with another.

What are insertions/deletions in gene mutations?

Addition or removal of nucleotides.

What are beneficial effects of mutations?

Can lead to new traits that help an organism survive.

What are harmful effects of mutations?

Can cause genetic disorders.

What are neutral effects of mutations?

May have no noticeable effect on the organism.

Why are mutations important?

They are the source of genetic diversity within a species, essential for evolution.

What is DNA?

The genetic material that contains instructions for all cellular functions.

What are genes?

Segments of DNA that code for specific proteins.

What are chromosomes?

Structures that carry genes.

What are codons?

Sets of three nucleotides that code for a specific amino acid.

What are proteins?

Molecules that carry out most of the functions in a cell.

Can all mutations be inherited?

Not all mutations are inherited; only those in germ cells can be passed on.

What happens to recessive mutations?

They may not be expressed in an individual if they inherit one copy of the mutated gene.

What should you research regarding mutations?

Specific genetic disorders caused by mutations.

What is a further exploration topic related to mutations?

The role of mutagens in environmental health.

How are mutations related to evolution?

Mutations contribute to genetic variation which is essential for evolution.
