Answer:
Explanation:
The nucleus is surrounded by a membrane called the nuclear envelope, which protects the DNA and separates the nucleus from the rest of the cell.
The 4 major bases that make up DNA would be Adenine, Thymine, Guanine and Cytosine. The pyrimidines which are Cytosine and Thymine are structurally similar to each other, as they both only contain a single Carbon containing ring. While Purines, which are Adenine and Guanine, contain 2 chemically bonded carbon containing rings with each other.
As per the base pairing in DNA. Adeline always pairs with Thymine with 2 hydrogen bonds, while Guanine pairs with cytosine with 3 hydrogen bonds.
The base pair that is not found in RNA would be Thymine, instead another pyrimidine, which is uracil is used instead for processes dealing with RNA molecules.

I can't explain how to fill it out right now because i have to go. If i can edit later i will.
Answer:
True
Explanation:
You can think of the ladder breaking apart as a zipper unzipping. When the two sides of the ladder are apart, free nucleotide bases attach to the bases already on the sides of the ladder, and two copies of the DNA are formed. The copies are the same as the original because adenine (A) usually pairs with thymine (T).
