Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these stores information?
A
lipids
B
carbohydrates
C
proteins
D
DNA
Explanation: 

Detailed explanation-1: -The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

Detailed explanation-2: -Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life.

Detailed explanation-3: -Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.

Detailed explanation-4: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Detailed explanation-5: -DNA is genetic material that contains plans for the design of living things, but DNA can also be used to store data created by living things. DNA is an attractive material for data storage – it is stable, writable, readable, and information dense.
