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.
B. DNA Replication in Bacteria. DNA Replication in Bacteria. In general, DNA is replicated by uncoiling of the helix, strand separation by breaking of the hydrogen bonds between the complementary strands, and synthesis of two new strands by complementary base pairing. Replication begins at a specific site in the DNA called the origin of replication (oriC). DNA replication is bidirectional from the origin of replication. To begin DNA replication, unwinding enzymes called DNA helicases cause short segments of the two parent DNA strands to unwind and separate from one another at the origin of replication to form two Y-shaped replication forks. These replication forks are the actual site of DNA copying (see Fig. 4).
