2. The group of 3 nitrogen bases in the mRNA message that is read together is called a _C_ __ __ __ __.
3. In dividing cells, the DNA is scrunched into _C_ __ __ __ __ __ __ __ __ __ __ so it can be moved.
4. The mRNA message tells the ribosomes which _A_ __ __ __ __ _A_ __ __ __ to put in next when it makes a _P_ __ __ __ __ __ __.
5. Adenine, thymine, guanine, cytosine, and uracil are all _N_ __ __ __ __ __ __ __ _B_ __ __ __ __.
6. Chromosomes are made when DNA wraps around _H_ __ __ __ __ __ __ __ to make bead-like structures called _N_ __ __ __ __ __ __ __ __ __ __.
7. M_ __ __ __ __ __ __ __ __ RNA is copied from DNA in the _N_ __ __ __ __ __ __, edited, and transferred to _R_ __ __ __ __ __ __ __ __ in the cytoplasm to be translated into a protein
8. The process of making a DNA copy is called _R_ __ __ __ __ __ __ __ __ __ __.
9. _N_ __ __ __ __ __ __ _A_ __ __ __ __ (like DNA and RNA) are made by joining _N_ __ __ __ __ __ __ __ __ __ subunits together in a chain.
10. T_ __ __ __ __ __ __ __ RNA has an _A_ __ __ __ __ __ __ __ __ region that matches the codon on an m-RNA message.
11. The process of making an RNA message from DNA is called _T_ __ __ __ __ __ __ __ __ __ __ __ __ and it happens in the _N_ __ __ __ __ __ __.
12. _R_ __ __ __ __ __ __ __ __ RNA is made by the _N_ __ __ __ __ __ __ __ __ and joins with _P_ __ __ __ __ __ __ __ to make ribosomes.
13. Another name for protein synthesis is _T_ __ __ __ __ __ __ __ __ __ __.
14. _R_ __ __ __ __ __ __ __ __ molecules attach to the _O_ __ __ __ __ __ __ __ to turn off the lac operon when _L_ __ __ __ __ __ __ is NOT present.
15. _H_ __ __ genes are found in EUKARYOTIC cells and control growth and differentiation in developing embryos.
16. _S_ __ __ __ __ __ __ __ __ __ __ __ __ are chromosomal mutations in which one nitrogen base replaces another in the gene code.
17. _F_ __ __ __ __ __ __ __ __ __ mutations that happen at the beginning of the code are more harmful than those at the end because they change more of the message.
18. Small pieces of code called _I_ __ __ __ __ __ __ are cut out of the RNA message before it is read; while _E_ __ __ __ __ stay in the message and are expressed.
19. 3n or 4n plants with _P_ __ __ __ __ __ __ __ __ __ are bigger and stronger, but humans with this condition don’t survive.
20. _T_ __ __ __ boxes help position the _R_ __ __ _P_ __ __ __ __ __ __ __ __ __ enzyme.
21. _U_ __ __ __ __ __ is the nitrogen base NOT found in _D_ __ __ and _T_ __ __ __ __ __ __ is the nitrogen base NOT found in _R_ __ __.
22. Nitrogen bases made with _O_ __ __ ring are called _P_ __ __ __ __ __ __ __ __ __ __ and nitrogen bases made with _T_ __ __ rings are called _P_ __ __ __ __ __ __.

23. In prokaryotic cells, a group of genes that work together is called an _O_ __ __ __ __ __.

24. James _W_ __ __ __ __ __ and Francis _C_ __ __ __ __ are the scientists who used Rosalind _F_ __ __ __ __ __ __ __’s X-ray images to figure out that DNA is shaped like a “twisted ladder” with _P_ __ __ __ __ __ __ __ __ __ and _S_ __ __ __ __ __ forming the sides of the ladder, _N_ __ __ __ __ __ __ __ bases forming the rungs, and _H_ __ __ __ __ __ __ __ bonds acting as “glue” to hold the two sides together. (OVER)

25. I_ __ __ __ __ __ __ __ __ __ are mutations in which a piece of code breaks, flips, and reattaches backwards; while _T_ __ __ __ __ __ __ __ __ __ __ __ __ __ move a piece of DNA to another non-homologous chromosome.

26. In _G_ __ __ __ __ __ __ __’s mice-pneumonia experiment, lethal bacteria passed genetic material to harmless bacteria in a process called _T_ __ __ __ __ __ __ __ __ __ __ __ __ __.

27. According to _C_ __ __ __ __ __ __ __‘s rules when making DNA, _A_ __ __ __ __ __ __ always bonds with _T_ __ __ __ __ __ __ and _C_ __ __ __ __ __ __ __ always bonds with _G_ __ __ __ __ __ __.

28. Viruses that infect bacteria (like the one used in _H_ __ __ __ __ __ __- _C_ __ __ __ __ ‘s blender experiment which proved DNA was the genetic material) are called _B_ __ __ __ __ __ __ __ __ __ __ __ __ __. 

29. _T_ __ __ __ __ __ __ __ __ __ __ are sequences of DNA that can jump from one location to another and are thought to be involved in increasing mutations in cells; they are sometimes called “_J_ __ __ __ __ __” genes.

30. A DNA molecule is said to be _A_ __ __ __- _P_ __ __ __ __ __ __ __ because the two complementary strands run in opposite directions.
