Hint: The inherited material present in an individual’s chromosomes that control a variety of visible characteristics and invisible characteristics is called DNA. They link the amino acids in an mRNA-specified order using tRNA molecules to carry amino acids. They are also used to read the mRNA three nucleotides at a time.

Complete answer: Gene is considered as the basic functional and physical unit of heredity. It consists of a specific sequence of nucleotides that codes for a particular protein at a given position on a given chromosome.
The part that transmits genetic information to proteins is the sequence of nucleotides.
The nucleotide sequence determines the sequence of amino acids in a polypeptide chain. By multiple nucleotide sequences, the expression of each protein within each cell type is selected—these form promoters and various enhancer and repressor sequences.
A base pair is defined as consisting of two nucleo-bases, a fundamental unit of double-stranded nucleic acids. These are bound to each other by hydrogen bonds. The base pair form the building blocks of the DNA double helix. The base pair contributes to the folded structure of both DNA and RNA. The rules of base pairing are: Adenine is complementary with Thymine: the purine adenine always pairs with the pyrimidine thymine, Cytosine is complementary with Guanine: the pyrimidine cytosine always pairs with the purine guanine.
A helical antenna is an antenna wound in the form of a helix consisting of one or more conducting wires. The most common type, A helical antenna made of one helical wire, is called monocular. Antennas with two wires in a helix are called bifilar and with four wires in a helix are called quadrifilar.
Hence, the correct answer is option is A.
