When food enters the stomach absorption begins. Although absorption is done in stomach, the majority of absorption is done in the small intestine. The absorption begins once the gastric juices, acids, and enzymes. The food is broken down into a liquid but not enough to pass through the body. That is where the small intestine pay a major role. The small intestine releases a chemical that allows the food to be broken down enough to pass through the body. Tissues and blood vessels are responsible for passing the nutrients throughout the body.

After DNA fragments with matching sticky ends are temporarily joined by complementary base pairing, the union can be made perman

STatiana [176]

Answer:

The correct option is b. DNA ligase

Explanation:

DNA ligase is an enzyme that joins DNA fragments. If two DNA fragments or molecules have complementary ends, the ligase can join them together to form a single and intact DNA molecule, without interruptions. This is because the ligase enzyme seals the space between the molecules to form a single DNA fragment.

The others enzymes have different functions:

DNA helicase is characterized by separating DNA from double strands into single strands and acts in DNA replication.

ATP methylase plays an important role in DNA replication when determining the beginning of replication that has already been replicated or not.

DNA polymerase is an enzyme that is responsible for catalyzing the polymerization of the new strand of DNA during the replication of this molecule.

Which of the following factors might cause checkpoint genes to interrupt cell division? Check all that apply. Neurological signa

Strike441 [17]

Answer:

Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.

Explanation:

All the three options given can cause checkpoint genes to interrupt cell division.

Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.

Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.
