Sequence of Amino Acids Encoded by the Given mRNA Sequences

To determine the sequence of amino acids encoded by the given mRNA sequences, we need to refer to the genetic code. The genetic code is a set of rules that determines how the sequence of nucleotides in DNA or RNA is translated into the sequence of amino acids in a protein.

Let's analyze each mRNA sequence and determine the corresponding sequence of amino acids:

a) АУААУУЦЦАУГААУГГЦУЦАЦЦГГЦГ

To decode this mRNA sequence, we can break it down into codons, which are groups of three nucleotides that code for a specific amino acid. Here is the breakdown:

- АУА: This codon codes for the amino acid Isoleucine. - АУУ: This codon codes for the amino acid Isoleucine. - ЦЦА: This codon codes for the amino acid Lysine. - УГА: This codon codes for the amino acid Stop.

Therefore, the sequence of amino acids encoded by this mRNA sequence is Isoleucine-Isoleucine-Lysine-Stop.

b) АЦАУГЦЦЦАААГГГУУУЦГАГГУГГЦУ

Let's break down this mRNA sequence into codons:

- АЦА: This codon codes for the amino acid Threonine. - УГЦ: This codon codes for the amino acid Cysteine. - ЦЦА: This codon codes for the amino acid Lysine. - ААГ: This codon codes for the amino acid Arginine. - ГГГ: This codon codes for the amino acid Glycine. - УУУ: This codon codes for the amino acid Phenylalanine. - ЦГА: This codon codes for the amino acid Serine. - ГГУ: This codon codes for the amino acid Valine. - ГЦУ: This codon codes for the amino acid Alanine.

Therefore, the sequence of amino acids encoded by this mRNA sequence is Threonine-Cysteine-Lysine-Arginine-Glycine-Phenylalanine-Serine-Valine-Alanine.

c) ЦГААУГГЦЦГАУГАГУГАУАЦУАЦУАГ

Let's break down this mRNA sequence into codons:

- ЦГА: This codon codes for the amino acid Arginine. - АУГ: This codon codes for the amino acid Methionine (Start codon). - ГЦЦ: This codon codes for the amino acid Proline. - ГАУ: This codon codes for the amino acid Aspartic Acid. - ГУГ: This codon codes for the amino acid Cysteine. - УАЦ: This codon codes for the amino acid Tyrosine. - УАЦ: This codon codes for the amino acid Tyrosine. - УАГ: This codon codes for the amino acid Stop.

Therefore, the sequence of amino acids encoded by this mRNA sequence is Arginine-Methionine-Proline-Aspartic Acid-Cysteine-Tyrosine-Tyrosine-Stop.

Please note that the provided mRNA sequences are hypothetical, and the actual amino acid sequences in proteins may vary depending on the specific gene and organism.
