RNA
Ribonucleic Acid
– R- Ribo
– N- Nucleic
– A- Acid
RNA- Structure
Nucleotide
– The monomer of RNA
– Consists of 3 parts
Nucleotide Part 1
5 carbon sugar
– Ribose
Nucleotide Part 2
Phosphate group
Nucleotide Part 3
Nitrogenous bases- 4
– Purines
Adenine (A)
Guanine (G)
Nucleotide Part 3
Nitrogenous bases
– Pyrimidines
Uracil (U) (replaces T of
DNA)
Cytosine (C)
Structure
Nucleotides form a
single strand
Types of RNA (p 205)
mRNA- messenger
RNA
– Copies and carries the
code/message from
DNA to the ribosome
in a cell
– Contains a codon (3
letter sequence)
Types of RNA (p 205)
tRNA- transfer RNA
– Picks up and carries
the amino acids from
the cytoplasm to the
ribosome
– Contains an anticodon
Types of RNA (p 205)
rRNA
– ribosomal RNA
– Makes up most of
ribosome
