<span>the base sequence of DNA is conserved during replication
through complementary base pairing. The first step of this process is to unwind the DNA's double helix. To do that is necessary the enzyme helicase break the hydrogen bonds between the nucleotides. These results in two strands that can become a template to use for replication. After that the enzyme DNA polymerase will form </span>hydrogen bonds with the nucleotides of the template DNA and new nucleotides, adenine will bond with thymine and
guanine will bond with cytosine.
The replication process has produced a new DNA molecule by using the original strand as a template and the new strand formed which is identical

<span>D) they lack DNA so they must use the DNA of the host cell
Viruses do in fact have their own DNA.</span>
Because it not asexual reproduction which means it has to inherit something from one parent and other things from the other parent
Answer:
cortisone is a lipid-soluble molecule hence can pass through the epidermis
Explanation:
Our adrenaline glands secrete various hormones including cortisol (also known as hydrocortisone) and corticosterone.
They belong to a group of steroid hormone bodies known as glucocorticoids and are used in a wide range of physiological processes such as inflammation regulation.
Pharmaceutical derivatives of these natural glucocorticoids include dexamethasone, fludrocortisone, prednisone, prednisolone, triamcinolone, which differ in strength. As all glucocorticoids have a similar effect, they all fall under the common name "cortisone".
