<u>amino acid</u> and <u>RNA (or anticodon)</u>

<u />

tRNA is used in the process of translation, which is when cells create a protein (polypeptide) from a strand of mRNA just came from the nucleus and is floating in the cytoplasm. This process occurs with the help of ribosomes!

A ribosome binds to an mRNA molecule, and tRNA's come swooping in one at a time to add amino acids to a growing polypeptide chain (protein).

On one end of the tRNA is a set of 3 RNA bases (called an <u><em>anticodon</em></u>), that binds perfectly to the opposing next 3 bases on the mRNA strand (called a <em><u>codon</u></em>) as it works it way through the ribosome. On the other side of the tRNA is the <em><u>amino acid</u></em> that the codon on the mRNA codes for, thus allowing the specific protein to grow 1 amino acid at a time.

Which statement best explains why the process of genetic engineering is important to the scientific community?
iVinArrow [24]
<h2><u>Answer:</u></h2>

Genetic designing gives crops that are more affordable to develop. One of the most serious issues that the world may look soon is a sustenance supply lack because of the expanding exponential development of the populace.

Genetic designing gives crops that are progressively generous, bigger and more affordable to develop that might be the response to mounting future issues. The capacity to control plants in the lab makes modifying their development design an a lot quicker change than numerous long periods of characteristic choice in the homestead and field.

Discuss and explain the correlation between thirst and kidney function​
Pachacha [2.7K]

The correlation between thirst and kidney function is the following:

Thirst is the regulator of the state of hydration, necessary to eliminate the osmotic load, it can help preserve kidney function.

The instantaneous perception of osmolarity in the blood allows us to generate the sensation of thirst.

In other words, this sensation is in turn caused by a high concentration of osmolytes (compounds that affect osmosis, or the way it is measured, osmolality or osmolarity) or by hypovolemia.

The receptors that control cellular dehydration are called osmoreceptors and are located in the lateral preoptic area.

Osmoreceptors detect this decrease in cellular water and trigger thirst, as well as the release of Anti-Diuretic Hormone into the bloodstream.

Antidiuretic hormone helps regulate the amount of water in the body by controlling the amount of water excreted by the kidneys.

Therefore, we can conclude that the sensation of thirst appears the sodium concentration is higher than normal, when drinking water, the concentration gradient is reduced, which allows the normal functioning of kidney function.

A eukaryotic mutation upstream of a particular gene has been identified that changes the sequence of the TATA box to GATA. How w
Allushta [10]

Answer:

Transcription factor binding would be reduced or eliminated, and transcription of the gene would decrease dramatically.

Explanation:

Mutation means the changing of the structure of the gene that results in the variant form which may be transmitted to the subsequent generations.  They are caused by the altering the the single base units in the DNA of the species.

In both eukaryotic as well as prokaryotic, the mutation can affect the diversity in the future generation of the cells.

The eukaryotic mutation of the gene affects the transcription of the gene as the transcription factor binding will be lowered or will be eliminated and the transcription of this gene will decrease.
