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.
DNA Replication. DNA replication is semi-conservative, one strand serves as the template for the second strand. Furthermore, DNA replication only occurs at a specific step in the cell cycle. The following table describes the cell cycle for a hypothetical cell with a 24 hr cycle. The DNA molecule is unwound and prepared for synthesis by the action of DNA gyrase, DNA helicase and the single-stranded DNA binding proteins. 2  A free 3'OH group is required for replication, but when the two chains separate no group of that nature exists.
