DNA
Linking nucleotides- guanine and cytosine thyamine and adanine
1 of 16
Nucleosomes
DNA wrapped around histone protiens held by another protien this helps supercoil
2 of 16
RNA
has uricil instead og thyamine
3 of 16
DNA replication
Helicase uncoils dna, RNA primase adds rna to both strands, dna primer allows p3 to start and find replciation, dna p1 removes rna primers and releases ligase seals gap
4 of 16
Nucleotide trisphosphate
building unit for dna
5 of 16
Helicase
enzyme unstrands dna by breaking hydrogen bonds
6 of 16
Gyrase
relieves the tension
7 of 16
polyermase 3
adds dna nucleotides in a 5 prime to 3 prime direction
8 of 16
polymereasee 1
removes rna and replaces with dna
9 of 16
sense strand
Transcribed to rna, sequence complamentry to rna
10 of 16
Sense strand
not transcribed into rna, dna version of rna
11 of 16
Transcription
rna p binds to promoter causing it to unwind, nucleotides bind to complamentry pairs, rna p bind ntp together, 5'-3' direction, when reaches terminator rna p detaches, dna unwinds
12 of 16
translation
mrna is decoded into a squence of amino acids
13 of 16
initiation
small subunit binds to mrna, initiator trna binds to start codon at p side, then large sub unit arrives
14 of 16
Elongation
2nd trna binds to A site, forms a peptide bond with amino acid, ribosome moves along, initiator leaves E site and 2nd moves into p site third moves into A site
15 of 16
Termination
Continues until it reaches stop codon, and release factor binds to A site polypeptide bond is released
