Other RNAs
- RIBOSOMAL RNA
- ROLE
- Provides scaffolding for ribosomes
- Has catalytic properties
- Joins amino acids together during RNA translation
- Provides scaffolding for ribosomes
- STRUCTURE OF RIBOSOME
- Eukaryotes have 60s and 40s subunit
which overall equals 80s
- Prokaryotes have 50s and 30s which
equals 70s overall
- Eukaryotes have 60s and 40s subunit
which overall equals 80s
- ROLE
- TRANSFER RNA
- STRUCTURE
- Anti codon
amino acid
attached to 3
prime
- Longer end is 3 prime
shorter end 5 prime
- ROLE
- Translates the message from the mRNA into a
long polypeptide chain
- Translates the message from the mRNA into a
long polypeptide chain
- WOBBLE
- tRNAs use wobble to recognise the codon, in the
third base of the anticodon. G can also pair with U
- A modified base called I is also found this can
base pair with A,C,U
- Means that less tRNA needed
- Means that less tRNA needed
- Normal base pairing still occurs
- A modified base called I is also found this can
base pair with A,C,U
- tRNAs use wobble to recognise the codon, in the
third base of the anticodon. G can also pair with U
- MANUFACTURE
- Several tRNA transcribed
together to form pre tRNA,
- Pre tRNA folds up by base pairing
- Cuts using RNAase P and D
- Base Modification
- Aminoacylation
- AMP along with tRNA is attached to AARS
with loss of pyrophosphate
- AMP lost and tRNA charged
- AMP along with tRNA is attached to AARS
with loss of pyrophosphate
- Base Modification
- Cuts using RNAase P and D
- Pre tRNA folds up by base pairing
- Several tRNA transcribed
together to form pre tRNA,
- STRUCTURE
