Protein Synthesis. 3 major processes: Replication → DNA copied to form 2 new DNA molecules Nucleus Transcription → DNA info copied to RNA Nucleus Translation → building a protein according to RNA instructions Cytoplasm. DNA Replication. DNA Replication.

Copied strand is called the complement strand (think “c” for copy)
BEGINNING OF DNA REPLICATION
DNA Polymerase adds nucleotides to create two NEW identical daughter molecules (A to T) and (G to C)
5’ 3’ direction only!!!
After SSBP’s bind to each template…
Lagging (daughter) strand
helicase + proteins:
RNA primer replaced by
DNA Polymerase & gap is
sealed by DNA ligase
DNA replication is necessary to create identical copies of DNA so it can be passed onto a new cell (cell division & reproduction)
and fix mistakes!
A new sugar-phosphate backbone is made for each new strand
Base pairs are added
Two strands are created in place of the original strand
