Molecular Biology Review

4. the nitrogen base that pairs with thymine in DNA
7. When two segments from different chromosomes trade place
9. When a Segment of DNA from one chromosome is added to another chromosome
11. a change in a single nucleotide in DNA
12. The process in which the genetic code in mRNA is read, one codon at a time, to make a protein
16. Anything in the environment that can cause a mutations
17. process of going from DNA to RNA through transcription and then RNA to protein through translation
19. Brings amino acids to ribosomes, where they are joined together to form proteins
20. Occur in other cells of the body, Confined to just one cell and its daughter cells, Will not be passed onto offspring
23. When a segment of DNA is Repeated
24. the transfer of genetic instructions in DNA into Messenger RNA (mRNA)
25. When a segment of DNA is lost so there is a missing segment in the Chromosome
26. is a region in the DNA that consists of one or more genes that encode the protein needed for specific functions
27. Copies the genetic instructions from DNA in the Nucleus, and Carries the instructions to the cytoplasm

1. Occur in gametes, Can be transmitted to offspring, Every cell in offspring will have the mutation
2. a type of mutation that includes deletion or insertion of one or more nucleotides
3. is a protein involved in regulating gene expression
5. turn a gene off
6. the nitrogen base that pairs with guanine in DNA
8. No change in amino acids
10. the shape of DNA
13. switch a gene on
14. When a segment of DNA is flipped upside down
15. the concentration of adenine was always about the same as the concentration of thymine
18. A change in the sequence of bases in the DNA
21. Changes from one amino acid to a different one
22. Changes from an amino acid to a stop or termination codon
