Niacin is another name for nicotinic acid. It is an organic compound that is synthesized in the liver. The essential amino acid that is utilized to synthesize niacin is tryptophan. To make 1 mg of niacin, your body needs 60mg of tryptophan. The biosynthesis of niacin requires riboflavin as well and vitamin B6.
The answer is D.
Answer:
Gene regulation in eucaryotic cells represents mechanisms that influence gene expression.
Explanation:
This gene expression is regulated via repressors or activators of transcription.
Gene expression is a process that contains information from a transcript gene and translates it into a functional gene product. End products of gene expression are proteins.
Gene regulation is a process that cells and viruses are using to regulate the transformation of gene information into gene products.
Transcription factors are those proteins that regulate gene transcription. Those factors help the real genes to enter the right cells in the body.
The expression of eukaryotic genes is controlled by transcription. This transcription is controlled by proteins that are connecting to regulatory sequences and change the RNA activity. Gene regulation process is developed by combining different proteins of regulation.

i think b. is the warmer the weather, the quicker the Silkworm will complete its life-cycle,
When cells makes a new compound, such as glycogen from many glucose molecules, usable energy is needed and is obtained by removing a phosphate group from ATP, producing energy plus ADP plus phosphate.
<h3>What is ATP?</h3>
This is referred to as adenosine triphosphate and is the energy currency of the cells.
This is usually formed from the synthesis of ADP and a phosphate group thereby making it the most appropriate choice.
