What is the expected gene product of the given nucleotide sequence when it undergoes protein translation?

Responses

Lys Gln Arg Asp Ala Glu

Leu Leu Cys Glu Ala Glu

Phe Val Ser Leu Arg Leu

Asn Asp Thr Leu Arg Leu

Answer 1

The expected gene product of the given nucleotide sequence when it undergoes protein translation is the peptide sequence Asn-Asp-Thr-Leu-Arg-Leu.

Step-by-step explanation:

The given nucleotide sequence is the mRNA transcript of a short peptide sequence in a human cell. To determine the expected gene product during translation, we need to use the genetic code. Each three-nucleotide sequence, called a codon, corresponds to an amino acid. By referencing the genetic code, we can decipher the peptide sequence encoded by the mRNA.

By looking at the given mRNA sequence, we can determine the corresponding amino acid sequence. The codons in the mRNA sequence are as follows: AAC-GAC-ACA-CUC-CGU-CUU. Referring to the genetic code, we can find the corresponding amino acids: Asn-Asp-Thr-Leu-Arg-Leu. Therefore, the expected gene product of the given nucleotide sequence, when it undergoes protein translation, is the peptide sequence Asn-Asp-Thr-Leu-Arg-Leu.

Answer 2

The expected gene product of the given nucleotide sequence when it undergoes protein translation is Lys Gln Arg Asp Ala Glu. This is derived from the mRNA sequence, which is AAC GAC ACA CUC CGU CUU. This mRNA sequence is translated into Amino Acid sequence, which is Lys Gln Arg Asp Ala Glu, by using the standard genetic code
