Because an organ is made up of several types of tissues, therefore several types of cells due to the fact that tissues are a group of cells of the same type that perform a specific function in an organism.
Answer:
both strands of the parent molecule act as templates
Explanation:
The process of DNA replication uses the existing parental DNA strands as a template. The enzyme helicase breakdown the hydrogen bonds between the base pairs of a DNA duplex to separate the two strands from each other. Each of these two DNA strands from a DNA duplex serves as a template for the process of DNA replication. Primase enzyme synthesizes primers on both the template strands which in turn are elongated by DNA polymerase enzyme.
