Cell differentitation is important because our body's need different type of cells to grow and also function
Answer:
It would be about 2H (or H-2) and 3H (or H-3) isotope
Explanation:
Answer: transcription, nucleus
Explanation:
In eukaryotic cell the process whereby the sequence of DNA bases is used to determine the sequence of bases in mRNA us called transcription and it occurs in the nucleus.
The DNA serves as the template strand. RNA polymerase binds to the promoter on the template DNA strand and synthesizes mRNA with RNA nucleotides. Genetic information of DNA is transcribed to messenger RNA. In eukaryotes this process occurs in the nucleus.
Lets calculate the parameters of the problem. Suppose that the width is x feet. THen, the length is x+30 feet. The area of this parallelogram is given by the product of length and width, hence x(x+30). This has to be equal to 600.
Hence, x is the solution to the equation x(x+30)=600.
x*x+30x=600 hence x*x+30x-600=0. This is a second degree equation and we can calculate Δ=b*b-4ac=3300. The general solution is given by:
.
Substituting, we get that x=-30/4+
or x=-7.5+25*
. This is the width; the length is given by x+30.
Answer:
Interphase (Synthesis stage)
Explanation:
Before a cell can undergo division (mitosis), it must first make a copy of its genetic material which each daughter cell will have. This process of DNA replication takes most of the time of the cell cycle, making the interphase, specifically the S phase, the longest phase of the cell cycle. The interphase stage occurs in three steps:
1. G1 phase: This is also called the first gap phase. The cell is biochemically active at this stage, hence it grows physically larger and makes copies of its organelle. The cell also accumulates building blocks of DNA molecules.
2. S phase: Also called Synthesis phase, the cell makes a copy of its DNA in its nucleus. DNA material (uncoiled chromatin) is replicated into two identical pairs. The centrosomes, which gives rise to the mitotic spindle, is also replicated. These spindles separate the sister chromatids during mitosis.
3. G2 phase: This is also called the second gap phase. It is the last step of interphase before mitosis begins. The cell makes protein and prepared for mitosis by rearranging its contents. It ends when mitosis begins.
