Answer:
DNA polymerase
Explanation:
DNA polymerase enzyme catalyses the reaction of adding nucleotide to growing complementary daughter strand of DNA in the direction of 5' → 3' during elongation in the process of replication. This process requires energy which is taken from nucleotides with three phosphate groups in their backbone similar to ATP (adenine triphosphate)
DNA Replication is when DNA multiplies and make exact copies of itself as part of gene transfer.
Explanation:
Worms are invertebrate animals with bilateral symmetry. Worms have a definite anterior (head) end and a posterior (tail) end. The ventral surface of worms and other organisms is the bottom side of the body, often closest to the ground. The dorsal surface is located on the upper part of the body facing the sky. The lateral surfaces are found on the left and right sides of the body. Figure 3.35 compares bilateral symmetry in a whale shark and a swimming plychaete worm. Organs for sensing light, touch, and smell are concentrated in the heads of worms. They can detect the kinds of environment they encounter by moving in the anterior direction
