B) tRNA carries amino acids to ribosome.
E) mRNA code is read to determine the sequence of amino acids in the protein.
Explanation:
Gametes are the genetically different kind of cells which are produced as a result of meiosis. Meiosis is a reductional division in which the chromosomes are reduced to half. Genetic variation in the gametes is due to crossing over between two non-sister chromatids of a homologous chromosomes during meiosis.
During meiosis, the 2 alleles for each gene stay together.
Answer:
(A) two
Explanation:
A heterodimeric protein consists of two polypeptides (a polypeptide is a chain of amino acids) that differ in amino acid composition, number or order in the chain sequence. Each polypeptide makes a different subunit of the protein.
One gene encodes one polypeptide, so if the protein has two different polypeptides, two genes are required to form this protein.
