Question

Given the DNA sequences:

DNA Strand 1: ACT TTC GAT
DNA Strand 2: CGA CAT TAG

What are the corresponding mRNA sequences, tRNA sequences, and amino acids for these DNA sequences?
a) mRNA: UGA AAG CUA; tRNA: ACU TTC GAU; Amino acids: Stop, Lysine, Leucine
b) mRNA: TGA TTC CTA; tRNA: ACT TTC GAT; Amino acids: Cysteine, Pheylalanine, Glycine
c) mRNA: UGA TTC GAU; tRNA: ACT TTC GAT; Amino acids: Stop, Pheylalanine, Aspartic acid
d) mRNA: TGA AAG CAT; tRNA: ACT TTC GAT; Amino acids: Cysteine, Lysine, Histidine

Answer 1

The corresponding mRNA sequences are ACU UUC GAU and GCU CAU UAG. The tRNA sequences are ACU TTC GAU and CGA GUA AUC. The amino acids for each mRNA sequence are Threonine, Phenylalanine, Aspartic acid, Alanine, Histidine, Stop.

Step-by-step explanation:

The DNA sequences given are:

DNA Strand 1: ACT TTC GAT

DNA Strand 2: CGA CAT TAG

To find the corresponding mRNA sequences, we need to convert T to U (since RNA uses U instead of T). Therefore, the corresponding mRNA sequences are:

mRNA Strand 1: ACU UUC GAU

mRNA Strand 2: GCU CAU UAG

The tRNA sequences are the complementary sequences to the mRNA strands. So, the tRNA sequences are:

tRNA Strand 1: ACU TTC GAU

tRNA Strand 2: CGA GUA AUC

To determine the amino acids for each mRNA sequence, we can reference the genetic code. Using the genetic code, the corresponding amino acids for each mRNA sequence are:

Amino acids for mRNA Strand 1: Threonine, Phenylalanine, Aspartic acid

Amino acids for mRNA Strand 2: Alanine, Histidine, Stop

Therefore, the correct answer is:

mRNA: ACU UUC GAU; tRNA: ACU TTC GAU; Amino acids: Threonine, Phenylalanine, Aspartic acid.
