Although very similar, the base pairs in DNA and RNA differ by one nitrogenous base.
In DNA, the four nitrogenous bases are Adenine, Thymine, Guanine, and Cytosine. Adenine always bonds to thymine (in DNA), they are connected by two Hydrogen bonds. Cytosine and Guanine are always bonded together. They are connected by three Hydrogen bonds.
However, in RNA, there is no thymine and instead, there is Uracil. That is the only nitrogenous base that is different. Cytosine still bonds to guanine, and adenine bonds to uracil.
I hope that helps!
Answer:
(D) To allow multicellular organisms to grow and replace damaged cells
Explanation:
The function of Mitosis is to allow multicellular organisms to grow and replace damaged cells.
We are talking about chemical reaction here. In a chemical reaction, substances that react are called reactants, and substances which are formed are called products. Atoms in the reactants break their bond, rearrange themselves and form new bonds to make the product. So no atoms are added or removed, which is called law of conservation of atoms/mass.
