1. Complete the unfinished DNA strand from below. 2. What m-RNA strand would be formed from the DNA strand that you just made in #1 above?

3. Using the codon chart in the lesson, what amino acids would be aligned from the following m-RNA strand?

A U G G C G G A A

4. If the first base in the sequence above (#3) were mutated to a C, what would that do to the amino acid sequence?

5. If you were given a single tiny chunk of a nucleic acid strand and asked if it was DNA or RNA, what things would you look for to tell?

Explanation:

1. is T G C A T because it is a DNA as it contains thymine.

2. so mRNA strand would be U G A C G U A as it is in RNA so it would be uracil with adenine.

3. is Met- Ala- Glu

4. if is mutated to a C then it would be C U G G C G A A

so it would be Leu-Ala-Glu.

5. you can look for if it contains thymine or uracil. If thymine then DNA if Uracil then RNA. you can also see if it is double or single strand. if double than DNA if single than RNA.

hope this helps you :)
