DNA/Chromosomal mutations

Front

What is mRNA read in chunks of three called?

Back

Codons are the sequences of three nucleotides in mRNA that correspond to specific amino acids.

Front

What is translocation in genetics?

Back

Translocation is a chromosomal mutation where a piece of one chromosome detaches and reattaches to a different chromosome.

Front

What mutation occurs when a nucleotide is added to a DNA sequence?

Back

Insertion is a mutation where one or more nucleotides are added to a DNA sequence.

Front

What happens during a deletion mutation?

Back

A deletion mutation occurs when a piece of a chromosome is lost.

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one nucleotide in a DNA sequence is replaced by another nucleotide.

Front

Define chromosomal mutation.

Back

Chromosomal mutations are alterations in the structure or number of chromosomes, which can affect gene expression and function.

Front

What is the difference between deletion and duplication mutations?

Back

Deletion removes a segment of DNA, while duplication involves copying a segment of DNA, resulting in extra genetic material.

Front

What is an example of a silent mutation?

Back

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

Front

What is the role of codons in protein synthesis?

Back

Codons specify which amino acids will be added during protein synthesis, determining the protein's structure and function.

Front

What is an inversion mutation?

Back

An inversion mutation occurs when a segment of a chromosome is reversed end to end.
