Resource summary

Nucleic Acids
1 Transcription
1.1 Unwind gene length
1.1.1 H bonds break Free RNA nucleotides to leading strands complementary base pairings mRNA leaves DNA recoils
2 Translation
2.1 mRNA attaches to ribosome
2.1.1 Triplet code, 3 bases per amino acid Coden on mRNA = 3 bases tRNA brings amino acid, anti-codon base pairs to codon
3 Replication
3.1 Semi conservative
3.1.1 N15 grow organisms Grow in N14 for 1 Take sample and centrifuge Repeat
3.2 Unwind (helicase)
3.2.1 Free DNA nucleotides complementary base pair DNA polymerase sugar phosphate (covalent phosphodiester) - condensation reaction
4 Subunit for DNA and RNA
4.1 DNA
