MICROANATOMY

Detailed explanation-1: -The nucleotide sequence of a gene, through the medium of mRNA, is translated into the amino acid sequence of a protein by rules that are known as the genetic code. This code was deciphered in the early 1960s. The sequence of nucleotides in the mRNA molecule is read consecutively in groups of three.

Detailed explanation-2: -It’s also critical to understand that the specific sequence of A, T, C, and G nucleotides within an organism’s DNA is unique to that individual, and it is this sequence that controls not only the operations within a particular cell, but within the organism as a whole.

Detailed explanation-3: -DNA molecules are composed of four nucleotides, and these nucleotides are linked together much like the words in a sentence. Together, all of the DNA “sentences” within a cell contain the instructions for building the proteins and other molecules that the cell needs to carry out its daily work.

Detailed explanation-4: -Genetic Code Genes are sequences of DNA nucleotides that carry and transmit the information specifying amino acid sequences for protein synthesis. Each DNA molecule contains many genes. The genome refers collectively to the total genetic information coded in a cell.
