DNA, RNA, PROTEINS STARTS WITH ? Name _______________________________

1. DNA that is spread out in the nucleus of a non-dividing cell so it can be read is called
_C_ __ __ __ __ __ __ __ __ .
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.

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,...
