Question

Cracking the Codon - 30 Points! - Refer to Screenshot

1. During replication, DNA is copied. Use your knowledge of DNA replication to replicate the original DNA sequence in the table below. Write the replicated DNA sequence in the table.

2. Now that you have replicated the DNA sequence, the next step is to transcribe it into RNA. Remember, in RNA adenine (A) is transcribed into uracil (U), thymine (T) is transcribed into adenine (A), and cytosine (C) is transcribed into guanine (G). Write the transcribed RNA sequence in the table.

3. Next you will translate the RNA into amino acids. Remember, three RNA bases in a row is called a codon, and each codon codes for a specific amino acid. You will use the chart on the following page to determine which amino acid each codon codes for. For each codon, start in the middle of the chart and work your way outward. For example, the codon CAG codes for glutamine.

4. Each amino acid in the table is denoted by a letter, for example glutamine is letter Q. You will use these letters to crack the code and find the mystery word. Write the letters in the table to fill in the blanks.

Answer 1

original dna strand

GGC GAG AAT GAA ACT ATT TGT AGC

1. replicated strand

CCG CTC TTA CTT TCA TAA ACA TCG

2. transcribed RNA sequence (replace T with U)

CCG CUC UUA CUU UCA UAA ACA UCG

3. translation (use the chart to figure out the proteins made

pro - leu - leu - leu - ser - stop - thr - ser

4. mystery code

*you need to do this, the question didn't provide me the table to make the code* please look back on your sheet
