 A and G (adenine and guanine), and two pyrimidines, C and T (cytosine and thymine); in mRNA, U (uracil) replaces T. The words of the alphabet comprise 3 letters, thus there are 43=64 permutations or words which are called codons. 61 of the 64 codons code for 1 of 20 amino acids. Since more than one codon codes for a particular amino acid the code is said to be redundant. Four of the 64 codons punctuate the message; one, AUG, is the start signal and three, UAG, UAA and UGA,   are stop <span>signals.</span>

The cell is the fundamental unit of structure and function in living things. All organisms are made up of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells. A cell is the smallest unit that is typically considered alive and is a fundamental unit of life.

<span>Meiosis I

Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. </span>Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.<span>

Why is it important for the cell membrane to allow materials to enter and leave the cell
umka21 [38]
<span>Cell membrane needs to allow and exit the materials that enter the cell because the cell needs nutrients and these nutrients are converted into molecules that aid in many cellular activities like repair, divide and form structures and biomolecules.
Also to excrete wastes and other harmful materials for the cell.
This continues because the cell wants to attain homeostasis.

Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. This is achieved through cellular processes in the body, the integumentary system regulates the body temperature, the hypothalamus –hunger and thirst of the individual and other interrelated organ systems that make the body healthy and in the state of equilibrium. Now, when diseases or disorders appear they disrupt the organ systems in the body thus, causing imbalance state –high fever, inability to focus and etc.<span>
