Transcription is the process by which a DNA sequence contained in the gene is copied in the form of an RNA molecule (a single-stranded molecule made up of RNA nucleotides).

Learn how to write complementary DNA sequences, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.

A codon is a sequence of three nucleotides, which codes for one amino acid. Living things read codons and use the genetic code to create proteins.

The DNA coding strand runs 5-prime to 3-prime and is the strand which matches the new RNA sequence, with the exception of uracil (in RNA) replacing thymine (in DNA).

An insertion mutation affects DNA by inserting one or more nucleotides into the DNA sequence. This changes the genetic code and thus can change the protein made. Is an insertion mutation harmful?

DNA keeps the nucleotide sequence in each gene, which can direct the body to make each amino acid in a protein, using the RNA molecule to carry the codon to where amino acids are put together.

In DNA, a point mutation occurs when genetic material is altered through the addition, deletion, or modification of a single base. Learn about the definition, types, diseases, and examples of ...

Compare missense, nonsense, and silent mutations. Learn about mutations and how they can affect proteins. See missense, nonsense, and silent mutation examples.

What is a point mutation? A simple point mutation definition is a change in one base in the DNA sequence and can be caused by a variety of internal and external factors.
