Answer:

Explanation:

Transcription is the process by which a DNA nucleotide sequence is used as a template for the synthesis of an RNA molecule, which can be mRNA, tRNA or rRNA, by means of the enzyme RNA dependent DNA polymerase. Transcription in prokaryotes and eukaryotes differs in several respects, so they are studied separately.

1. The precursors of RNA synthesis are the four ribonucleotides 5 ’triphosphates (adenosine 5’-triphosphate, guanosine 5’-triphosphate, cytosine 5’-triphosphate and uridine 5’-triphosphate).

2. In the condensation reaction between the 5 'trisphosphate group of the incoming nucleotide and the 3'-OH group of the last nucleotide in the chain, the incoming nucleotide loses its two terminal phosphate groups. Its α group is used in the phosphodiester bond that binds it to the chain. This reaction occurs at the polymerase catalytic site.

How do wildfires help control plant disease? a. Wildfires are more likely to kill off plants that are likely to spread disease.
Bezzdna [24]

Answer:

d. All of the above

Explanation:

Wildfires are useful in controlling the ecosystem disturbed due to some diseases and insects.

With the help of wildfire, there will be a temporary loss in some region but it will lead to extraordinary growth.

Wildfire improves the soil quality by decomposing the organic material and renewing the soil nutrients.

There are chances of habitat loss but it will increase the production of food grazers.

Certain plants can be reproduced through wildfire due to cracking their seeds.
