People inherit dna from their parents. exact copies of each parent's dna are
passed on to the offspring. which characteristic of dna replication is most
important in how the genetic code is preserved from one generation to the next?
dna follows base-pairing rules.
dna always remains in the nucleus.
both parents' dna have identical backbones.
replication takes place at many places at the same time.

Answer:

People inherit DNA from their parents. Exact copies of each parent's DNA are  passed on to the offspring.

A. DNA follows base-pairing rules.

This characteristic of DNA replication is most  important in how the genetic code is preserved from one generation to the next.

Explanation:

In living organism, the nucleotide DNA strand is copied by a base pair of DNA that complement each other. This is the process of DNA replication through which the genetic code of one generation is transferred to the offspring of that trait.

In the replication, the old strands of DNA form a completely new DNA stand with double helix of which one strand is new and the other is the old one. In this process, the genetic information or code is passed from one generation to the other.

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.
