Answer 1

The structure of DNA and RNA. DNA is a double helix, while RNA is a single helix. Both have sets of nucleotides that contain genetic information. Deoxyribonucleic acid or DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce.

Answer 2

•DNA is Dioxyribose Nucleic Acid.
•It's also referred to as the 'THE MASTER MOLECULE'.
•Chromosomes are made up of DNA.
•It contains 1 phosphate molecule,1 sugar molecule (ribose), 4 nitrogenous bases namely Adenine, Guanine, Cytosine, Thymine.
•It was discovered by Friedrich Michael.
•It's double helix structure was proposed by Watson and Crick.
•Adenine and Guanine are called 'Purines' while Cytosine and Thymine are called 'Pyrimidines'
•Adenine always pairs with Thymine while Cytosine will pair with Guanine.
•DNA carries genetic characteristics
