Using this codon chart, can someone help me give my the mRNA,tRNA,and amino acids from the original DNA sequence “ACT TTC GAT”

nevsk [136]

Answer:

DNA: ACT TTC GAT

mRNA: UGA AAG CUA

tRNA: ACU UUC GAU

AA: stop-lysine-leucine

Explanation:

mRNA is the complementary sequence of the DNA strand and tRNA is a complementary sequence of mRNA sequence. mRNA is a sequence of bases that is formed by encoding the DNA sequence in the complementary pattern during transcription.

tRNA is complementary of the mRNA code to produce the amino acid which is decided by the codon ( a three- base sequence of mRNA) what amino acid be present in what sequence.

Thus,

DNA: ACT TTC GAT

mRNA: UGA AAG CUA

tRNA: ACU UUC GAU

AA: stop-lysine-leucine (however, after the stop codon amino acid chain terminated in any protein)

If you inherit the genotype AO for blood from your parents, what blood type do you have?

alexandr1967 [171]

<span>If you inherit the genotype AO for blood from your parents, you have blood type A. Regarding blood types, there are three possible alleles: A, B, and O. Both alleles A and B are dominant to allele O. So, if a person has the genotype AO, allele A will mask the effect of allele O, and the person will have blood type A.</span>
