Why does DNA need to be copied into mRNA?

Biology
1 answer:
larisa86 [58]3 years ago

mRNA will serve as reference book that contains information as the DNA and its sequence is complementary to the DNA template.

The transfer of information in a DNA strand to a new molecule of messenger RNA is known as transcription. Thus, the process of transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. However, DNA is copied into mRNA because mRNA will serve as reference book that contains information as the DNA and its sequence is complementary to the DNA template.

The formation of a cell plate is beginning across the middle of a cell and nuclei are re-forming at opposite ends of the cell. W
Kay [80]

Answer:

a. a plant cell undergoing cytokinesis

Explanation:

Cytokinesis is the process where the cytoplasm divides after mitosis to form two different daughter cells from the parent cell. Animal cell divides by just a cleavage formation. Plant cells have an additional step of formation of cell plate because they have cell wall.

At the end of anaphase and beginning of telophase when the two new daughter nuclei have just formed, cell plat formation begins. Secretory vesicles from golgi body come at equator of the dividing parent cell. These vesicles release all the materials required for cell wall formation. The materials start to form the cell plate which moves outwards till it reaches the division site of parent cell wall. Slowly cell wall arises from cell plate and cytokinesis occurs giving rise to new plant cells.
