A) protein
B) nucleic acid
C) plasmids
D) amino acids
Correct Answer: D
Solution :
The three successive bases in the genetic code signifies amino acids. It is the relationship of amino acid sequence in a polypeptide and nucleotide/base sequence in mRNA. If the sequence of base pair changes or added or deleted the amino acid coded by it also changes. Proteins are the building blocks of cells. A particular protein is coded by particular sequence of nucleotides. Nucleic acid is a complex organic compound in living cells that consists of a chain of nucleotide. They are of two types: DNA (Deoxy ribonucleic acid) and RNA (Ribo Nucleic Acid). Plasmid is a structure in bacterial cell consisting of DNA that can exist and replicate independently of the chromosome. It provides genetic instruction for certain cell activities.
