The correct answer is Transfer of RNA.
Transfer of RNA acts as the delivery truck which delivers amino acid to the ribosome for the synthesis of protein and then leaves empty again. Transfer RNA is termed as an adaptor molecule which is composed of RNA which have 76-90 number of nucleotides in length.
It is a link which is between amino acids sequence and mRNA of proteins. The work of tRNA is to specify which sequence from genetic code corresponds to amino acids. mRNA encodes the protein as series of contiguous codons. Its structure can be decomposed into a primary and secondary structure.
To exhibit a recessive trait, an individual must have two recessive alleles responsible for the trait. One recessive allele is from a mother and another is from a father. However, if a person has one dominant and one recessive allele, it will not exhibit the recessive trait. This is because recessive allele will be masked by the dominant allele. So, parents must be heterozygous (one dominant and one recessive allele) and must give their recessive alleles to the offspring so that only offspring exhibit the recessive trait.
