3. Messenger RNA
7. state that DNA from any species of any organism should have a 1:1
9. enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes.
11. a compound which is one of the four constituent bases of nucleic acids. A purine derivative, it is paired with thymine in double-stranded DNA.
12. a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.
13. an explanation of the flow of genetic information within a biological system
14. adds nucleotides to the three prime
15. a compound found in living tissue as a constituent base of nucleic acids. It is paired with guanine in double-stranded DNA.

1. see DNA.
2. a compound that occurs in guano and fish scales, and is one of the four constituent bases of nucleic acids. A purine derivative, it is paired with cytosine in double-stranded DNA.
4. is a term used to describe the physical structure of DNA.
5. the action of copying or reproducing something.
6. a compound which is one of the four constituent bases of nucleic acids. A pyrimidine derivative, it is paired with adenine in double-stranded DNA.
7. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
8. a nucleic acid present in all living cells that has structural similarities to DNA
10. the haploid set of chromosomes in a gamete or microorganism, or in each cell of a multicellular organism.
