Rna

• ribosomes made from RNA AND PROTEINS
• Name the complementary base pairs in RNA.

  • H-bonds between adenine (A) + uracil (U)
  • H-bonds between guanine (G) + cytosine (C)
• Describe the structure of messenger RNA (mRNA).

  • Long ribose polynucleotide (but shorter thanDNA).
  • Contains uracil instead of thymine.
  • Single-stranded & linear (no complementary base pairing).
  • Codon sequence is complementary to exons of 1gene from 1 DNA strand.
• RNA

  • ribose
  • phosphate group
  • nitrogenous bases A U C G
• adenine + uracil
• an RNA molecule is a relatively short polynucleotide chain
