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. 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>

During G1 phase, the cell grows in size and synthesizes mRNA and protein that are required for DNA synthesis. Once the required proteins and growth are complete, the cell enters the next phase of the cell cycle, S phase. The duration of each phase, including the G1 phase, is different in many different types of cells.
to begin with in G1 segment, the cellular grows bodily and will increase the volume of each protein and organelles. In S phase, the mobile copies its DNA to supply two sister chromatids and replicates its nucleosomes. subsequently, G2 section entails similarly cellular boom and business enterprise of cellular contents.
G1 - segment is likewise called anaphase, as in the course of this section the cellular shops ATP for cellular department.
The G1 phase is frequently referred to as the increase phase, due to the fact this is the time in which a cell grows. in the course of this phase, the cellular synthesizes diverse enzymes and vitamins which can be wished later on for DNA replication and cellular department.
G1 section collectively with the S phase and G2 section comprise the long increase period of the cell cycle cell department referred to as interphase that takes region before cellular department in mitosis (M phase). all through G1 segment, the cellular grows in size and synthesizes mRNA and protein which are required for DNA synthesis.
In G1, cells accomplish most in their growth; they get larger in size and make proteins and organelles wanted for regular functions of DNA synthesis. here, proteins and RNAs are synthesized, and, extra in particular the centromere and the alternative components of the centrosomes are made.

Answer:
Volume of stock 50X TAE buffer required is 4 mL;
Volume of distilled water needed = 196 mL
The researcher will measure 4 mL of the stock 50X TAE solution using a pipette into a 250 mL volumetric flask. The researcher will then add 196 ml of distilled water to make it up to the 200 ml mark.
Explanation:
The following values are given: initial concentration, final concentration and final volume
Initial concentration,C₁ = 50X
Final concentration, C₂ = 1X
Final volume, V₂ = 200 mL
Initial volume, V₁ = ?
Using C₁V₁ = C₂V₂
V₁ = C₂V₂/C₁
V₁ = 1X * 200 mL/50X
V₁ = 4 mL
Therefore, volume of stock 50X TAE buffer required is 4 mL
Volume of distilled water needed = 200 mL - 4 mL
Volume of distilled water needed = 196 mL
The researcher will measure 4 mL of the stock 50X TAE solution using a pipette into a 250 mL volumetric flask. The researcher will then add 196 ml of distilled water to make it up to the 200 ml mark.
