If a molecule of DNA has 200 pairs how do the DNA molecules fit into the cell?

DNA is able to fit into a cell because of its shape. DNA is a double helix that can bend and twist in all sorts of directions. An easier example to visualize is a spaghetti noodle in a bowl. Stretched out straight, it wouldn’t fit in the bowl, but once coiled or twisted up, it would conform to the shape of sand bowl. Well, DNA can coil up just like a noodle can, which gives it the ability to become compact enough to fit into the nucleus of a cell. The way DNA molecules can all fit into the cell is because they coil around histone proteins, which once in a tight enough coil, become nucleosomes which can stack to then become chromatin. That is how about 6 feet of DNA can be squeezed into a microscopic cell.

mixer [17]

Answer:

(08) and (32)

Explanation:

To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.

The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.

In your own words, describe what information the visible DNA fingerprint provides for each DNA sample

Sidana [21]

Answer:

The visible DNA fingerprint can help extract DNA which, after analysis, can accurately identify the suspect or perpetrator of the crime.

Explanation:

DNA Fingerprinting:

DNA fingerprinting is a molecular analysis tool that can help identify a suspect in a crime through DNA extracted from fingerprints.
Specific patterns in the DNA, known as polymorphisms, can be identified through DNA fingerprinting.
The DNA fingerprinting process involves:

Extraction and purification of the DNA from the fingerprint.
PCR amplification to obtain high yield.
Fragmentation of the DNA by use of restriction enzymes.
Gel electrophoresis analysis of the fragmented DNA.
Analysis of gel to compare the size of the bands.
