Within every cell, there are genes that tell the cell when to start the process of DNA replication and mitosis and when to stop.

There are also "checkpoint" genes that will interrupt or stop cell division if a problem occurs.
Which of the following factors might cause checkpoint genes to interrupt cell division?
Check all that apply
A. Neurological signals sent from the brain tell the cell to stop
B. The cell's DNA has been damaged somehow
C. There are not enough nutrients to support cell division

Answer:

B. The cell's DNA has been damaged somehow

Explanation:

Cell division is a must for every living cell. Before a cell can divide, its genetic material (DNA) needs to be duplicated. However, all conditions necessary for the DNA replication and actual division (mitosis or meiosis) must be favorable. The set of genes that makes sure of this are called CHECKPOINT genes. Checkpoint is an internal controlled mechanism employed by the cell to ensure that its division occurs without errors. Any errors during this process can cause the cell division process to be halted.

Checkpoints occur after certain stages of the cell cycle and each is dependent on whether certain demands are met by the cell. For example, the G1 checkpoint will not allow S-phase (Synthesis of DNA) to take place if it is observed that the DNA of that cell has been damaged in any way. The cell using checkpoints prevent that cell from dividing and multiplying in order not to magnify the problem.

Answer:

B. The cell's DNA has been damaged somehow

Explanation:

It has been shown that the cell cycle is stopped when DNA damage is detected. For example, it has been discovered that mutations in  G2 / M genes are responsible for non-stop cell cycle during cancer progression

Explain how villi are adapted for efficient absorption of sugar molecules
salantis [7]

Answer:

Villi are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.

Part of: Wall of small intestine

Latin: small intestinales

Which microscope do you use to see parts of a cell?
marissa [1.9K]
A simple light microscope should be enough. you can adjust it to a higher magnification. electronic microscope the magnification might be too high for this, but sure it can do the work too, especially when you're looking for a more detailed information

What section of dna are used in dna fingerprinting
Alja [10]

Answer:

<em><u>R</u></em><em><u>epetitive DNA sequences "minisatellites." The two major uses for the information provided by DNA-fingerprinting analysis are for personal identification and for the determination of paternity. DNA fingerprinting is based on DNA analyzed from regions in the genome that separate genes called introns.</u></em>
