DNA and RNA
1 synthesis of dna and rna goes in the 5' to 3' direction in terms of the newly synthesized strand
1.1 incoming nucleotide always attaches to the 3' carbon
2 transcription is creation of mRNA from dna template
2.1 Txn
3 Rna polymerase binds at the promoter
3.1 transcription goes in 3'-5' direction in terms of dna
3.1.1 rna produced it transcription undergoes rna processing
3.1.1.1 primary rna transcript is immature
3.1.1.2 in processing the 3' UTR is chewed back till the AAUAAA region is present
3.1.1.2.1 the poly A tail added to end
3.1.1.2.1.1 made of adenine strand
3.1.1.2.1.2 shortens over time
3.1.1.2.1.2.1 when short enough mRNA is degraded
3.1.1.2.1.2.1.1 allows for transport out of nucleus
3.1.1.3 5' cap
3.1.1.3.1 protects 5' end
3.1.1.3.2 enzymes are present to degrade single stranded RNA
3.1.1.4 splicing
3.1.1.4.1 during transcription
3.1.1.4.2 introns taken out of transcript
3.1.1.4.3 exons kept and expressed
3.1.1.4.4 SnRNPs come together to form a splicesome
4 spliceosome and ribosome
4.1 protein/rna structures where the rna part is what catalyzes the chem reaction
4.2 mutations can occur in splice sites
5 translation
5.1 the ribosome is responsible for protein sythesis
5.2 translation of the genetic code from nucleotide sequence to amino acid sequence is proformed by the transfer rna (trna)
