Braun Genetics

2. An enzyme that cleaves bonds within the nucleic acid.
5. A radioactive nucleic acid, DNA or RNA, used to identify a complementary fragment.
6. This is the bread and butter of genetics. DNA--->mRNA---->Polypeptide (or protein). (Two words separated by a "_").
8. The physical trait that is expressed.
10. An enzyme that recognizes the sequence of DNA and lyses the duplex. (Two words. A "_" separates them and counts as a space.)
13. Uptake of DNA from the environment by a cell.
16. Last name of the man who discovered the "Transforming principle" in 1928.
17. DNA replication by separation of parental strands. This word states how one part of the DNA is the original strand and one is the complementary daughter strand.
18. This bond is formed between two nucleotides. A to T have only two while G and C have 3!
19. When a G-C base pair is replaced with an A-T base pair.
20. A nitrogenous base written as "A" when writing out a genetic sequence.
21. An acronym. DNA sequence of triplets that can be translated into amino acids starting with an initiation codon and ending with a termination codon.

1. This bond is formed from two hydroxl groups. Water is the product and it the bond that makes the "chain" in DNA's backbone.
3. A mutation that causes no phenotypical effect. (Two words separated by a "_")
4. Written as "U" and is a nitrogenous base only found in RNA.
7. A method of capturing an image of radioactive materials on film.
9. The parts of DNA that encode protein. These are not excised during transcription.
11. Changes in the DNA sequence and can occur spontaneously or are induced by mutagens.
12. The physical exchange of DNA that sometimes occurs during Prophase I of meiosis.
14. When a purine is replaced with a pyrimidine or a pyrimidine is replaced with a purine.
15. Large assembly of RNA and proteins that synthesizes polypeptides under direction from an mRNA template.
