A mutation is a change in the nucleotide sequence of DNA.

The process is called transcription.

The letter 'c' represents a nucleotide.

DNA replication is the process of making a copy of DNA to create another DNA molecule.

Junk DNA refers to segments of DNA that are not part of genes.

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

The three main components are a sugar, a phosphate group, and a nitrogenous base.

Ribosomes are the cellular structures where proteins are synthesized by translating mRNA.

Transcription is the process of creating mRNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Genes are segments of DNA that contain the instructions for making proteins.
