Molecular Genetics

3. a molecule that contains the genetic code that is unique to every individual.
5. noncoding, intervening sequence within a eukaryotic gene.
7. change in the DNA sequence of a cell.
8. nucleic acid simaliar to DNA. However it contains the sugar ribose, and uracil replaces thymine, usually single stranded.
11. RNA,(rRNA)The type of RNA that associates with proteins to form ribosomes in the cytoplasm.
13. which cause mutations.
14. synthesis,the process by which amino acids are linearly arranged into proteins through the involvement of ribosomal RNA, transfer RNA, messenger RNA, and various enzymes.
15. RNA,(tRNA) smaller segments of RNA nucleotides that transport amino acids to the ribosome.
16. the process of making an exact copy of something.
18. micrograph in which the pairs of homologous chromosomes are arranged in decreasing size.
19. coding sequences that remain in the final mRNA.
21. the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm.

1. a change in the DNA sequence of an organism
2. the use of biology to develop new products, methods and organisms intended to improve human health and society.
4. polymerase,The enzyme that catalyzes the addition of appropriate nucleotides to the new DNA strand.
6. three base code in DNA or mRNA.
9. a base, a sugar, and a phosphate.
10. regulation,The ability of an organism to control which genes are transcribed in response to the enviroment.
12. RNA,(mRNA) Long strands of RNA nucleotides that are formed complementary to one strand of DNA.
17. section of DNA that contains the genes for proteinsfor a specific metabolic pathway.
20. ligase,The enzyme that connects the okazaki fragments.
