Answer:
The initial step in the formation of an aminoacyl-tRNA is activation of the amino acid by reaction with ATP
Explanation:
In protein synthesis, the first step involves the formation of an aminoacyl-tRNA. This reaction is catalyzed by the the Mg²⁺-dependent enzymes known as aminoacyl t-RNA synthetases and occurs in two steps.
The first step of the reaction of the formation of an aminoacyl-tRNA is the activation of the amino acid by the attachment of an AMP molecule formed from the hydrolysis of ATP to AMP and pyrophosphate. The aminoacyl adenylate intermediate is bound to the enzyme in this initial step. Subsequently, in the second step of the activation of the amino acid, the aminoacyl adenylate intermediate is then transferred to its specific tRNA. The pyrophosphate formed in the first step is hydrolyzed to 2 phosphate molecules by a pyrophosphatase.
The overall reaction step is illustrated below:
Amino acid + tRNA + ATP -----> aminoacyl-tRNA +AMP + 2Pi
This translates to symptoms such as weight gain and fatigue.
<h3>Symptoms of hypothyroidism</h3>
Hypothyroidism is defined as the endocrine disorder in which the thyroid hormone is deficient or under secretion of the hormone.
The thyroid hormone is used for the following purposes in the body:
- Regulates the rate at which your body uses calories (energy).
- It affects weight loss or weight gain and which is called the metabolic rate.
When the thyroid hormone is deficient, the following is bound to occur:
Therefore a decrease in the metabolic rate of the body will lead to fatigue and gaining of weight.

Well, basically, everything is made of atoms and cells. Those are youre building blocks for every life unit. The subunits of proteins are amino acids. These acids combine (in different combinations) to form different proteins.
The subunits of starch are carbohydrates. They build to form molecules of starch.
The
subunits of DNA are nucleic acids. These mix with other things to form
DNA. It is like the protein where different combinations create
different DNA strands/molecules.
Answer:
D) 60 i think
Explanation: in 2016 the rural population was 20 and the urban population was 60 so if you start counting from 20 in 2016 up to 80 in 2016 its 60
