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
Plants gather water and nutrients/minerals from the ground through their roots as part of the process to produce food.
Answer:
There are a total of <u>71,551 employees</u> in the company.
Explanation:
Let the number of employees in the company be 'x'.
Given:
Number of employees in one country = 24900
As per question:
34.8% of total employees = 24900
⇒ 
So, there are a total of 71,551 employees in the company.
FALSE
All organisms use this "mechanism" to defend their food and shelter. Birds protect their nest just like all other animals and they fight for food.

<span>Its called Doxycycline-induced esophageal ulcer. Its not common. I have been taking Doxy for many years for acne without any complication. Then one night I took a single pill, drank half a glass of water, and went to bed. I woke up with mild heartburn. A few days later, I was in immense pain. I felt burning up and down my whole chest. I was bloated, gassy, and couldnt burp. The pain was so severe, it caused me have a migrane. The pill dissolved in my esophagus, and caused an ulcer. It was my fault for not drinking a full glass of water, and going straight to bed. Im in treatment now, and am scheduled for an esophagogastroduodenoscopy. Im feeling a little better already after the first day of treatment, but ulcers take 4-8 weeks to heal.</span>
