THE MOLECULAR BASIS OF INHERITANCE

DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What aspect of the DNA molecule encodes hereditary information concerning an organism’s traits?
A
the molecular mass
B
the sequence of base pairs
C
the distribution of electrical charges
D
the folded three-dimensional shape
Explanation: 

Detailed explanation-1: -The sequence of bases pairs encodes hereditary information concerning an organisms trait.

Detailed explanation-2: -DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base-A, C, T, or G-can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.

Detailed explanation-3: -Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder-a shape known as a double helix.

Detailed explanation-4: -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.

Detailed explanation-5: -Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.
