Deoxynucleotide

from class:

General Biology I

Definition

Deoxynucleotide is a molecule consisting of a nitrogenous base, a deoxyribose sugar, and one or more phosphate groups. It is the basic building block of DNA.

congrats on reading the definition of deoxynucleotide. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. Deoxynucleotides are essential for DNA replication and sequencing.
  2. There are four types of deoxynucleotides in DNA: dATP, dTTP, dGTP, and dCTP.
  3. In whole-genome sequencing, deoxynucleotides are used to synthesize new strands of DNA.
  4. Deoxynucleotides can be labeled with fluorescent tags for detection during sequencing.
  5. Mutations in the sequence of deoxynucleotides can lead to genetic disorders.
