Storyboard Text

  • Each DNA strand contains a unique sequence or code of genetic information.
  • Did you know DNA stands for deoxyribonucleic acid?
  • Today we will be talking about DNA.
  • There are 4 nitrogenous bases: adenine, guanine, cytosine, and thymine.
  • Nucleotides and Nitrogenous Bases
  • Each Nucleotide is made up of 3 basic components: 5-carbon sugar called called deoxyribose, a phosphate group, and a nitrogenous base.
  • DNA is made up of units called Nucleotides.
  • Base Pairs
  • Adenine forms a base pair with thymine, and cytosine forming a base pair with guanine.
  • DNA consists of two strands. The two strands are held together by hydrogen bonds.
  • The ends of a DNA molecule are called 3' and 5' ends, based on the numbering of carbon atoms in deoxyribose sugars.
  • When two strands assemble in a double helix, the two strands always face in opposite directions; the 5' end of one strand is paired with the 3' end of the other strand.
  • 3' and 5'
  • Chromosomes and Proteins
  • Eukaryotic chromosomes contain DNA wrapped around proteins called histones. The strands of nucleosomes are tightly coiled and supercoiled to form chromosomes.
  • Most Prokaryotes have only a single circular chromosome. The chromosome holds most of the organism's DNA.
  • Transcription and Translation
  • During transcription, RNA polymerase uses on strand of DNA as a template to assemble nucleotides into a strand of RNA.
  • During translation, the cell uses information from messenger RNA to produce proteins.
