The sequence UUA on an mRNA chain is a codon that codes for the amino acid leucine. In the genetic code, each codon consists of three nucleotides, and UUA is one of several codons that specify leucine. This means that during protein synthesis, if the ribosome encounters UUA, it will incorporate leucine into the growing polypeptide chain.
To determine the anticodons for the given mRNA sequence (AUGAAUGGCUGAUCUGA), we first identify the codons by breaking the sequence into groups of three nucleotides: AUG, AAU, GGC, UGA, CUG. The corresponding anticodons for each of these codons, using the base pairing rules (A-U and C-G), are UAC, UUA, CCG, ACU, and GAC. Thus, the sequence of the anticodons is UAC UUA CCG ACU GAC.

The sequence of amino acids in the polypeptide will be Phenylalanine-Leucine-Isoleucine-Valine-Proline. This is because each group of three mRNA bases (codon) corresponds to a specific amino acid, as determined by the genetic code.
In mRNA, the base pairing for the DNA sequence AATCGTA is determined by the complementary RNA bases. The correct pairing would be UUA CGUA, where adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G), while guanine (G) pairs with cytosine (C) and thymine (T) pairs with adenine (A).
No, there is not just one mRNA code for each amino acid. In the genetic code, multiple codons (three-nucleotide sequences) can specify the same amino acid, a phenomenon known as redundancy or degeneracy of the genetic code. For example, the amino acid leucine is encoded by six different codons (UUA, UUG, CUU, CUC, CUA, CUG). This redundancy helps mitigate the effects of mutations in the DNA sequence.
If the tRNA has the sequence UUA, then the mRNA it reads from will have the sequence complementary to UUA, which is AAU. RNA uses the nucleic acid uracil instead of the DNA counterpart, thymine.

AAT in mRNA codon represents the sequence adenine-adenine-thymine, which codes for the amino acid asparagine in protein synthesis. This codon is recognized by the corresponding tRNA molecule carrying asparagine during translation in the ribosome.

A possible base sequence for the DNA strand could be: TAC GCT TGA ACT GGC ACC TCA. This complementary sequence would transcribe into mRNA with the message for glutathione production.
Before we look at the complimentary mRNA sequence of the given DNA sequence, let us remember that RNA contains uracil (U) in place of Thiamine (T) The querry sequence is: t-a-c-c-t-c-g-c-a-a-c-t So the mRNA sequence would be: A U G G A G C G U U G A

G is paired with C, U with A orT with A, U is used in RNA and T is used in DNA.Now just replace the letters with their paired letter.C G C U A U A G C-beforeG C G A U A U C G-aftertherefore your answer is GCGAUAUCG.hope this helps :)
