A technique used in determining the protein binding region in dna (e.g, binding region of RNA polymerase) is called DNA footprinting

One technique used to determine protein binding regions (eg, RNA polymerase binding regions) of DNA is called DNA footprinting. A DNA footprint shows where a protein binds to a DNA molecule. In this technique, a pure DNA fragment labeled with 32 P at one end is first isolated. A trace amount of DNA endonuclease is then added to the mixture of core protein and radiolabeled DNA. RNA sequencing (RNA-Seq) harnesses the power of high-throughput sequencing methods to gain insight into the cellular transcriptome. Compared to previous Sanger sequencing and microarray-based methods, RNA-Seq offers much broader coverage and resolution of the dynamic nature of the transcriptome.

How are babies made and how long it takes for the baby to form in the mothers belly

For women, the possibility of pregnancy begins in the ovaries. A woman is born with 1 to 2 million eggs, more than a lifetime's supply. The eggs begin dying off almost immediately and she never produces more. The average egg lives only about 24 hours, so it has to be fertilized soon for pregnancy to happen. If it doesn't get fertilized on time, it either dissolves or is absorbed by the body. When an egg is fertilized, its own genetic material and the genetic material of the sperm that got to the egg first combine to create a new cell that starts dividing rapidly. A woman isn't actually pregnant until that new bundle of cells (called the embryo) travels down the fallopian tube and attaches to the wall of the woman's uterus. The average pregnancy lasts for 38 weeks from the date you conceive (called conception). However, doctors usually date your pregnancy from the first day of the woman's last menstrual period. Using this method, a pregnancy is said to last 40 weeks, or 280 days.

50 POINTS PLS HELP MEEE

The cell placed within the hypertonic solution will quickly become dehydrated due to the concentration gradients and osmosis.

Though I cannot provide the drawing of the cell, I can describe what a hypertonic solution is and what effect it would have on the cell.

A hypertonic solution is a solution that when compared to another solution or object, has a higher concentration of solute. If made into a drawing, this would look like the cell is in water, but said water contains a large amount of solute, like sugar for example.

Hypertonic solutions can cause water to move. The water moves through a process known as Osmosis, which is the tendency of water to move towards a location that has a higher concentration of solute, in order to dissolve this concentration. Since the liquid inside the cell has a lower concentration of solute than the environment, the water inside the cell will escape through osmosis and can severely dehydrate the cell.

The light-independent reactions of photosynthesis, also known as the Calvin cycle, must repeat six times in order for a cell to

tensa zangetsu [6.8K]

Answer:

Molecules brought in: 3CO2, 9ATP, 6NADPH

Molecules Produced: 1G3P, 9ADP, 6NADP+ +H+

Molecules used and Regenerated: 3RuBP, 5G3P

Explanation:

1. Molecules brought in and utilized in the light-independent reaction or Calvin cycle:

-CO2 from outside the cell

-Molecules take energy from the light-dependent reactions

2. Molecules produced during the light-independent reaction or Calvin cycle that leave the cycle:

-Energy-carrier molecules that have lost some energy\

-3-carbon molecules that store energy

3. Molecules produced in the cytoplasm from the end products of the Calvin cycle:

-Organic molecules such as glucose

Thus, Molecules brought in: 3CO2, 9ATP, 6NADPH

Molecules Produced: 1G3P, 9ADP, 6NADP+ +H+

Molecules used and Regenerated: 3RuBP, 5G3P
