Final answer:
To determine the amino acid sequence of the DNA strand ATC-TAC-GAG-GAT, it is transcribed to mRNA and then translated using a genetic code table. The resulting mRNA sequence UAG-AUG-CUC-CUA corresponds to - (stop), Met, Leu, Leu, with the amino acid sequence likely starting from the AUG codon as Met-Leu-Leu.
Step-by-step explanation:
To determine the amino acid sequence of the DNA strand ATC-TAC-GAG-GAT, we would first need to transcribe this DNA sequence into the corresponding mRNA sequence. In mRNA, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G). The DNA bases thymine (T) pairs with adenine (A), and guanine (G) pairs with cytosine (C). Therefore, the DNA strand ATC-TAC-GAG-GAT would transcribe to the mRNA sequence UAG-AUG-CUC-CUA. To translate this mRNA sequence into an amino acid sequence, we would use a codon wheel or genetic code table.
Using the standard genetic code, the mRNA codons UAG, AUG, CUC, and CUA correspond to the amino acids - (stop), methionine (Met), leucine (Leu), and leucine (Leu), respectively. However, the UAG codon is a stop codon and does not encode an amino acid, which generally indicates the end of the amino acid chain. In this case, the codon is present at the beginning of the sequence, which is unusual for a coding sequence. Usually, the translation would start at the AUG codon, which is the start codon in many organisms. Therefore, the protein sequence, starting from the N-terminal, would read as Met-Leu-Leu if translation started at the AUG codon
