What is the charecteristics of an alveolus

Alla [95]

Each alveolus is cup-shaped with very thin walls.
It’s surrounded by networks of blood vessels called capillaries that also have thin walls.
The oxygen you breathe in diffuses through the alveoli and the capillaries into the blood.
The carbon dioxide you breathe out is diffused from the capillaries to the alveoli, up the bronchial tree and out your mouth.
The alveoli are just one cell in thickness, which allows the gas exchange of respiration to take place rapidly.

DNA replication of chromosomal DNA in a cell requires all of the following, EXCEPT A) DNA polymerase B) primase C) helicase D) R

Viktor [21]

Answer:

The correct answer is D)RNA polymerase

Explanation:

In DNA replication many enzymes and proteins are required to replicate a DNA template. For initiation of DNA synthesis the two DNA strands must be separated which is done by helicase.

Then primase adds short nucleotide sequence and initiate DNA replication. After that DNA polymerase acts and adds nucleotide at the 3' end of growing DNA strand. Ligase is the enzyme that joins the two Okazaki fragments that are created in the lagging strand.

RNA polymerase is not required in DNA replication and it works in transcription therefore the correct answer is RNA polymerase.
