Given the following three mRNA sequences, 2 code for the same protein. Which two?
#1. AGU UUA GCA ACG AGA UCA
#2 UCG CUA GCG ACC AGU UCA
#3 AGC CUC GCC ACU CGU AGU

Respuesta :

Answer:

#2 & #3

Explanation:

both have the same amino acids. like leucine

Knowing that more than one codon codes for the same amino acid during protein building, we can affirm that sequences #2 and #3 code for the same protein.

How does translation occur?

During protein synthesis, the ribosome reads mRNA molecules from the 5' to 3' extremes.

While doing it, tRNA recognizes the codons of the molecules and adds the correct amino acids.

Codons are short sequences of three nucleotides that code for one amino acid.

So the sequence of codons determines the sequence of amino acids in the building protein.

There are 64 possible codons,

  • The start codon AUG is the most common sequence used by eukaryotic cells and placed near the 5' extreme of the molecule.

  • The end codons are UAA, UAG, UGA. They indicate where to stop protein synthesis.

  • The remaining codons code for one amino acid in the protein. Since there are only 20 amino acids in nature, more than one codon codes for the same amino acid.

Knowing this, we can build the protein by reading the mRNA sequences.

#1. AGU UUA GCA ACG AGA UCA

     Met    Leu   Ala   Thr   Arg   Ser

#2 UCG CUA GCG ACC AGU UCA

       Ser   Leu   Ala   Thr    Ser    Ser

#3 AGC CUC GCC ACU CGU AGU

       Ser   Leu   Ala   Thr   Arg    Ser

Sequences 2 and 3 code for the same protein.
