Answer:
The nucleotide sequence of a DNA codon is TAG. In an mRNA molecule transcribed from this DNA, the codon has the sequence 5'-<u>AUC-3'</u>. In the process of protein synthesis, a transfer RNA pairs with the mRNA codon. The nucleotide sequence of the tRNA anticodon is <u>3'-UAG-5'</u>. The amino acid attached to the tRNA is <u>Isoleucine</u>.
Explanation:
In the process of protein synthesis the mRNA contains the sequence of nucleotides —transcribed from the DNA— that defines the sequence of amino acids that a synthesized protein will have.
Codons are triplets of nitrogenous bases present in mRNA, which encode an amino acid, as well as the start and end of protein synthesis.
Anticodons correspond to triplets of bases present in transfer RNA (tRNA), which correspond with mRNA codons. tRNA is responsible for coupling amino acids to the polypeptide chain being synthesized. In view of this:
<em>- DNA triplet: TAG</em>
<em>- Codon mRNA: 5'-AUC-3'
</em>
<em>- Anticodon tRNA: 3'-UAG-5'</em>
<em>- Amino acid: Isoleucine</em>
The variation may already exist within the population, but often the variation comes from a mutation, or a random change in an organism's genes.

Answer:
16/64 = 1/4
Explanation:
This is a typical trihybrid cross involving three genes T, P and Y. A plant with genotype TTPpYy is crossed with a plant recessive for all traits (ttppyy).
According to Mendel's law of independent assortment, each allele for each gene will get sorted into the following 8 gametes with only 4 different: TPY, TPy, TpY, Tpy, TPY, TPy, TpY and Tpy.
The recessive parent, ttppyy will produce tpy, tpy, tpy, tpy, tpy, tpy, tpy and tpy.
Hence, using a punnet square, 64 offsprings will be produced with only 16 of them heterozygous dominant for the three traits with genotype (TtPpYy). Hence, proportion is 16/64 equivalent to 1/4.
<span>Amino acids are considered as the building blocks of protein's, so amino acid rich food simply means protein rich food. There are 20 classifications for amino acids but nine of them are essential since our body can't make them. Usually in diet important amino acids are Lysine (C6H14N2O2), Leucine (C6H13NO2), Valine (C5H11NO2), Tryptophan (C11H12N2O2), Isoleucine (C6H13NO2) Phenylalanine (C9H11NO2) and Threonine
(C4H9NO3).</span>
