Question

Consider DNA coding sequence below.

5'- ATG CTG TTT GTA CGG GAC TAA-3'

A) whatis the template sequence that corresponds with this sequence ? (include all 5 and 3 prime ends)

B) what is the tRNA sequence that would be created from the above ?

C) what is the tRNA sequence that each tRNA would have when matching with each codon in part B? write the entire sequence of tRNA needed.

D) what is the amino acid sequence that would be created from the DNA sequence above?

E) circle the codons on your mRNA sequence.

F) Put rectangles around the anticodons of your tRNA sequence.

Explanation / Answer

Coding strand is complementary to template strand. Therefore the template strand is

5’TTA GTC CCG TAC AAA CAG CAT 3’

Or 3’ TAC GAC AAA CAT GCC CTG ATT 5’

*The mRNA made from template strand is

5’ AUG CUG UUU GUA CGG GAC UAA 3’

**The tRNA sequence would be 3’ UAC - GAC - AAA - CAU - GCC - CUG - AUU 5’

The amino acid sequence will be 3’ Tyr-Asp-Lys-His-Ala-Leu-Ile 5’

*The codons on mRNA sequence are underlined (instead of circle)

**The anticodons of tRNA sequence are made into italics separated by a dash (instead of rectangle)
