Genetics: Part 1

3. a small RNA molecule that helps build proteins by matching amino acids to messenger RNA
4. Any change in the DNA sequence of a cell
5. enzyme that catalyzes the synthesis of long chains of nucleic acids by adding nucleotides one by one, following the sequence of a template strand
10. enzymes that are capable of catalyzing the reaction of joining two large molecules by establishing a new chemical bond
11. thread-like structures located inside the nucleus of a cell
13. made up of a double-stranded helix
14. information in a strand of DNA is copied
16. enzyme that synthesizes short RNA sequences called primers
17. present in all living cells that has structural similarities to DNA
18. the formation of a peptide bond between the carboxyl group at the end of a growing polypeptide chain and a free amino group on an incoming amino acid
19. made from a DNA template during the process of transcription

1. a cell makes proteins using the genetic information carried in messenger RNA
2. the process by which the genome's DNA is copied in cells
6. type of cell division in sexually reproducing organisms
7. large biomolecules that play essential roles in all cells
8. the basic building block of nucleic acids
9. the basic unit of heredity
12. enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes
15. producing two identical nuclei
16. composed of amino acids
