Question

1. fill in the complementary dna strand by using the dna base pairing rules.
2. fill in the correct mrna bases by transcribing the bottom dna strand.
3. translate the mrna codons and find the correct amino - acid using the codon diagram.
4. write in the amino acid on the trna molecule.

Explanation:

Step1: Find complementary DNA strand

In DNA, A pairs with T and G pairs with C. Given DNA strand is ATGGTAGCTAACCTT. Complementary DNA strand is TACCATCGATTGGAA.

Step2: Transcribe bottom DNA strand to mRNA

When transcribing DNA to mRNA, T is replaced by U, A pairs with U, G pairs with C. Using bottom DNA strand TACCATCGATTGGAA, mRNA is AUGGUAUCGAUUGGAA.

Step3: Translate mRNA codons

mRNA codons are read in groups of 3. AUG - Methionine, GUA - Valine, UCG - Serine, AUU - Isoleucine, GGA - Glycine, A - (incomplete codon, usually stop if full stop codon is reached).

Step4: Find tRNA anticodons

tRNA anticodons are complementary to mRNA codons. So for AUGGUAUCGAUUGGAA, tRNA anticodons are UACCAUAGCUAAUCCUU.

Answer:

Complementary DNA: TACCATCGATTGGAA
mRNA: AUGGUAUCGAUUGGAA
Amino - acids: Methionine, Valine, Serine, Isoleucine, Glycine
tRNA: UACCAUAGCUAAUCCUU
