Join the stitches. What this means is you need to join the knitting yarn to the work so it is one continuous circle. Hold the needle where the cast on began in your left hand and hold the other needle in your right hand.
It is also required that fragments of DNA (genes) have to be copied to code for particular bodily function. It is essential that the replication of it is EXACT. In order for replication to occur, the following must be available. 1  The actual DNA to act as an exact template. 2  A pool of relevant and freely available nucleotides. 3  A supply of the relevant enzymes to stimulate reaction. 4  ATP to provide energy for these reactions.
Explain how the structure of DNA, suggested by Watson and Crick, is a mechanism for how it replicates. The two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase.This enzyme makes the complementary strand by finding the correct base through complementary base pairing, and bonding it onto the original strand.As DNA polymerases can only extend a DNA strand in a 5â² to 3â² direction, different mechanisms are used to copy the antiparallel strands of the double helix.his enzyme makes the complementary strand by finding the correct base through complementary base pairing, and bonding it onto the original strand.
