NEET BIOLOGY

Detailed explanation-1: -DNA molecules are made up of smaller parts called nucleotides. So, a gene is a specific stretch of nucleotides within a chromosome’s DNA. DNA is made up of four types of nucleotides.

Detailed explanation-2: -Gene. A segment of a DNA molecule (a sequence of bases) that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism.

Detailed explanation-3: -A gene is a stretch of DNA that contains the instructions for making or regulating a specific protein. Genes that make proteins are called protein-coding genes. In order to make a protein, a molecule closely related to DNA called ribonucleic acid (RNA) first copies the code within DNA.

Detailed explanation-4: -The segments of DNA that code for specific traits are called genes.

Detailed explanation-5: -The genetic code dictates which proteins the cell manufactures. Proteins are strands of amino acids. The sequence of nucleotides in DNA genes determines the order of amino acids in a protein. This is the direct connection between your genes and your traits.
