contains 4,288 genes
Watson & Crick;
define & describe
the basic unit of DNA structure;
made up of phosphate, deoxyribose sugar and a nitrogen base
each deoxyribose sugar bonds covalently in a repeating pattern with _____ ______________
which carbon atom on the deoxyribose does it (do they) bond to
final binding of nicks in DNA during synthesis and repair
strand of DNA ORIENTED in the 3' to 5' direction is called the
5' to 3'
new nucleotides are always added in this direction to form the new strand. the OLD strand has the opposite orientation to accommodate the attachment.
The lagging strand needs this to begin replication: ______
runs in the opposite direction (3'-5') and must be replicated backwards away from the replication fork, so the DNA P3 can add the nucleotides in the necessary 5' to 3' order.
