BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment. For example, scientists can use sequence information to determine which stretches of DNA contain genes and which stretches carry regulatory instructions, turning genes on or off.

Detailed explanation-2: -Concept 23 A gene is a discrete sequence of DNA nucleotides. Mendel described a gene as a discrete unit of heredity that influences a visible trait. Beadle and Tatum defined a gene as the discrete directions for making a single protein, which influences a metabolic trait.

Detailed explanation-3: -DNA sequencing refers to the general laboratory technique for determining the exact sequence of nucleotides, or bases, in a DNA molecule. The sequence of the bases (often referred to by the first letters of their chemical names: A, T, C, and G) encodes the biological information that cells use to develop and operate.

Detailed explanation-4: -DNA is responsible for building and maintaining your human structure. Genes are segments of your DNA, which give you physical characteristics that make you unique. Together, your body has a complete instruction manual that tells your cells how to behave.
