Answer:
CGC AUA CCG - RNA
CGC ATA CCG - DNA
Explanation:
Uracyl (U) is present in RNA instead of Thymine (T)
Also opposite RNA/DNA molecules pair with each other.
Adenine pairs with Uracyl (RNA)/Thymine (DNA)
Cytosine pairs with Guanine (both RNA & DNA)
These would be the elements in row 2 the alkaline metals. Elements in a row usually share many qualities such as electon reactivity as well as similar characteristics like the fact that many alkaline metals are considered Cations, ions with positive charges. Some examples are beryllium and calcium.
