DNA is a double helix consisting of two strands orientated in an __________ configuration meaning the 5' to 3' direction of one strand runs counter to direction of the other strand.

Respuesta :

DNA is a double helix consisting of two strands orientated in an _antiparallel_ configuration meaning the 5' to 3' direction of one strand runs counter to direction of the other strand.

How is DNA composed?

DNA is a nucleic acid.

Nucleic acids are linear polymers composed of nucleotides joined by their extremes.

Nucleotides are monomers composed of

  • a sugar,
  • a phosphate group, and
  • a nitrogenated base.

Nitrogenated bases are adenine, guanine, cytosine, and thymine

These nucleotides together compose a strain or a helix.

A DNA molecule is composed of two parallel strains.

The bases of each strain pair the bases of the other strain,

  • Adenine pairs with thymine,
  • Guanine pairs with cytosine.

The direction of these strains in the molecule is opposite to each other, which means that they are antiparallel to each other.
