Resource summary
DNA and RNA
synthesis of dna and rna goes in the 5' to 3' direction in terms of the newly synthesized strand
incoming nucleotide always attaches to the 3' carbon
transcription is creation of mRNA from dna template
Txn
Rna polymerase binds at the promoter
transcription goes in 3'-5' direction in terms of dna
rna produced it transcription undergoes rna processing
primary rna transcript is immature
in processing the 3' UTR is chewed back till the AAUAAA region is present
the poly A tail added to end
made of adenine strand
shortens over time
when short enough mRNA is degraded
allows for transport out of nucleus
5' cap
protects 5' end
enzymes are present to degrade single stranded RNA
splicing
during transcription
introns taken out of transcript
exons kept and expressed
SnRNPs come together to form a splicesome
spliceosome and ribosome
protein/rna structures where the rna part is what catalyzes the chem reaction
mutations can occur in splice sites
translation
the ribosome is responsible for protein sythesis
translation of the genetic code from nucleotide sequence to amino acid sequence is proformed by the transfer rna (trna)
