Primase

Synthesizes RNA primers during DNA replication (DNA dependent RNA polymerase)

Telomeres

DNA sequence repeats found at the end of linear chromosomes that do not code for RNA or a polypeptide.

Helicase

Unwinds the DNA double helix

Ligase

Joins DNA fragments together to generate a continuous DNA strand

Topoisomerase

Relieves stress caused by the unwinding of the DNA double helix

Primary structure of proteins

Amino acid sequence of a polypeptide

Tertiary structure of proteins

Three-dimensional structure of a single polypeptide

Secondary structure of proteins

Structure of a polypeptide maintained by hydrogen bonding interactions between amino acid backbone atoms

Quaternary structure of proteins

Protein structure level involving more than one polypeptide
