Biology 1001A Lecture Notes - Lecture 6: Semiconservative Replication, Chromosome, G0 Phase
Document Summary
Researchers define functional as anything that looks like anything that would ne expressed and therefore have said about 80% is functional; misconception. Maybe if it true but its not function to make us. Antiparallel means each of these single strands of dna has a 3 end and a 5" end. This gives the molecule a kind of direction. Those two strands fit together in opposite directions, such that at the end of the molecule one of the strans is a 3" and is a 5" ; antiparallel. This one molecule gives rise to 2 daughter molecules. The bases are being added to the 3" end. Nucleotides are being added to the free 3" end hydroxyl. Every dna polymerase in the known universes extends the 3" oh; only does this elongation. Because polymerase only knows how to extend the 3". All the proteins sticking together, called that a replisome. Replisome is active as a structure called the replication fork.
