Answer:
<h2>
Codon
</h2>
Explanation:
The sequence of DNA is transcribed into mRNA, containing the sequence for protein synthesis, protein is synthesized according to the codons in mRNA. This sequence of nucleotide on DNA/ RNA is divided into a series of three nucleotide units, and one unit of three nucleotide is known as codons.
There are overall 64 codons, 61 codons out of 64 codons, codes for overall 20 amino acids, and the remaining three are stop codons.
These there codon do not code for any amino acid.
And these 61 codons, they code for total 20 amino acids. So one amino acid can be coded by one or more than one codons.
Answer:
a. allow a variety of molecules to cross the cytoplasmic membrane
Explanation:
The cells have different molecules in its membrane. As a membrane the main function of it is to regulate the income and outcome of substances that the cell needs or the cell has like some wastes.
Some of these molecules can be some proteins like the permeases, that is going to regulate the solutes that can enter the cell, but since they are non specific, that means that can not make the difference among one carbohydrate and another (as an example).
Cellular respiration and photosynthesis are essential to the carbon cycle because cellular respiration involves the intake of oxygen o2 and the exhale of carbon-dioxide co2 into the atmosphere. Where photosynthesis uses the carbon dioxide and water to create oxygen and sugars through energy to repeat the cycle. Respiration in general is a process where carbohydrates are turned into dihydrogen monoxide or water and co2(carbon dioxide). Living organisms together throughout the biosphere and atmosphere work together to continue this because carbon itself is an organic substance.
