<h2>Answer: </h2>

The correct option is A, adenine will be first base.

<h3>Explanation:</h3>

Template DNA is 5'-ATAGGCCGT-3' and partially synthesized okazaki fragment is 5'-CCTA-3'.  So the next fragment will be 5'-ACGG-3'.

So first base will be adenine.

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.

Why can food chains
lana66690 [7]

Answer:

A. Because energy is lost at every level.

Explanation:

energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.

Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).

This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.

Hope this helps, have a lovely day :)
