Detailed explanation-1: -Each gene’s code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T)-in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.

Detailed explanation-2: -Broadly speaking, a genotype is the genetic constitution of an individual organism. For example, my genotype is my specific genetic make-up – not the genetic make-up of humans in general. A phenotype, on the other hand, is made up of the observable traits of an organism.

Detailed explanation-3: -A genotype is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.

Detailed explanation-4: -In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.

Detailed explanation-5: -Hello students, our next topic for MCQ is ‘Genetic code’. In the living organisms, DNA is a genetic material that carries information. Genetic code is form of information in the mRNA that is needed to direct synthesis of protein.
