Sequence of amino acids in a polypeptide chain of protein molecule coresponds to the sequence of nucleotides on mRNA for that pr

tamaranim1 [39]

Answer:

330

Explanation:

A codon is the sequence of three nucleotides on mRNA that refers for particular amino acid during translation (protein synthesis) process. The four nucleotides arrange themselves in various combinations to produce different codons. The tRNA with corresponding anticodon attach the particular amino acid to polypeptide chain during translation.

Remember there is always a stop (UAA) and start codon (AUG) for the synthesis of polypeptide and stop codon does not contribute for any amino acid. It just terminate the polypeptide chain synthesis. We know that a codon is made up of three nucleotide so our calculation will be.

993-stop codon =990

990/3=330

So that's why 330 amino acid will be incorporated in the polypeptide chain.

If 2 parents-both heterozygous for particular traits in a dihybrid cross are mated, how many different phenotypes will result in

andrezito [222]

If the parents are both heterozygous for particular traits their genotype would be: AaBb x AaBb ( this cross would be the F1 generation while the P generation is the one that originated the parents).
This cross would result in the folowing genotypes:
AABB
AaBB
Aabb
aaBB
aaBb
aabb
Dominant for A and B: 9/16
Dominant for A but recessive for B: 3/16
Recessive for A but dominant for B: 3/16
Recessive for A and B: 1/16
ratio: 9:3:3:1
To answer you the possible phenotypes is difficult because your question is missing information about what each gene does, but I know it would be 4 different phenotypes.
