C - Level
1. CTT CAT CTG ACA
2. ACG AUA AGU CCC
3. Four - Adenine (A), Thymine (T), Guanine (G), Cytosine (C)
4. Double Helix
5. Nucleus
6. C. Proteins
7. DNA has 2 strands; RNA has 1
8. met - gly - trp - ser - stop
B & A Level
1. DNA has the sugar deoxyribose; RNA has ribose; DNA - A pairs with T; RNA - A pairs with U
2. 3
3. mRNA
4. mRNA is made by copying one side of the DNA; mRNA leaves nucleus to find ribosome
5. mRNA is read 3 bases at a time (codon) and amino acids are put together in the right order
6. changes in DNA
7. mutation can cause the incorrect proteins to be made: could lead to disease or cancer
8. sometimes the mutation results in the same amino acid being made
9. D
10. nucleus
11. ribosome
12. amino acids
13. (picture labeling - see notes for reference)
14. mRNA is copying one side of DNA; mRNA leaves nucleus
15. mRNA enters a ribosome and is read 3 bases at a time. tRNA brings over the amino acid to assemble the protein.
