The three main worm phyla are flatworms, roundworms, and segmented worms. Roundworms have a digestive tube that has two openings. Segmented worms have a closed circulatory system in which blood is enclosed in blood vessels. These are important steps in the evolutionary development of animals.
Answer:
What is this?
Explanation:
Well Ik what it is, but what happens when I look it up??

Nucleotides lining up along the template strand according to base pairing rules process helps to preserve the genetic information stored in DNA during DNA replication
Option D
<h3><u>Explanation:</u></h3>
The DNA is a semi conservative molecule from the genetic information storing point of view. The genetic information is stored there in form of the alignment and arrangement of the nitrogen bases. These nitrogen bases are replicated just in order to conserve the genetic information.
During protein synthesis, same nitrogen bases get denoted in the RNAs and this gives the particular protein which is required in the body. No molecule present in the body can destroy the DNA and its alignment. It’s conserved as long as no external molecule or force destroys it. So it’s conserved in a very safe way.
