Using the red, blue, yellow and green beads, devise and lay out a three color code for each of the following letters (codon). For example Z = green : red : green.

In the spaces below the letter, record your code.

C: E: H: I: K: L:

RYG BYB YYY BRG RBY RBB

M: O: S: T: U:

GRG YBR GYR RGY GBR

Create codons for: Start: Stop: Space:

YRG BGY GBY

What does the sentence say now? (re-write the entire sentence)

Mutations are simply changes in the sequence of nucleotides. There are three ways this occurs:

1.Change a nucleotide(s)

2.Remove a nucleotide(s)

3.Add a nucleotide(s)

Using the sentence from exercise 1B:

1) Change the 24th bead to a different color. What does the sentence say now (re-read the entire sentence)? Does the sentence still make sense?

2) Replace the 24th bead and remove the 20th bead (remember what was there). What does the sentence say (re-read the entire sentence)? Does the sentence still make sense? If it doesnt make sense as a sentence, are there any words that do? If so, what words still make sense?

3) Replace the 20th bead and add one between bead numbers 50 and 51. What does the sentence say now? Does the sentence still make sense?

I only want help on questions #1-3, thank you!
