Question

question 1 1 pts rna and dna have the same pyrimidine bases but different purine bases. true false question 2 1 pts what term is often used to describe certain arrangements of atoms attached to the carbon core of many organic molecules? functional group monomer polymer prostaglandins question 3 1 pts all proteins have which four elements? carbon, oxygen, hydrogen, and sulfur carbon, oxygen, hydrogen, and nitrogen carbon, oxygen, sulfur, and nitrogen carbon, sulfur, hydrogen, and nitrogen question 4 1 pts

Explanation:

• Question 1: DNA and RNA have different pyrimidine and purine bases. DNA has thymine as a pyrimidine and RNA has uracil instead. Adenine and guanine are purines in both but the overall base - composition is different.
• Question 2: A functional group is a specific group of atoms within a molecule that is responsible for characteristic chemical reactions of that molecule and is attached to the carbon - core of organic molecules.
• Question 3: Proteins are made up of amino acids, and all amino acids contain carbon, oxygen, hydrogen, and nitrogen. Sulfur is present in some amino acids but not all proteins have sulfur.

Answer:

• Question 1: False
• Question 2: functional group
• Question 3: carbon, oxygen, hydrogen, and nitrogen
