1. Organic molecules are the living components made
of carbon rings and to which hydrogen, oxygen, and nitrogen are
attached. They play a vital role in the building blocks of life as
every organism for their survival on earth needs these organic
molecules. The basic unit of life DNA and RNA are also made of
organic molecules. The basic structure of DNA is composed of carbon
to which phosphate and nitrogen base are attached.
Nucleic Acids are made of nucleotides mainly purines and
pyrimidines. The two purines Adenine and Guanine and three
pyrimidines Cytosine, thymine, and, Uracil are the bases that carry
genetic information from one generation to another. DNA and RNA are
composed of nucleic acid. The structure of DNA contains a pentose
sugar which is deoxyribose, a phosphate group, and a nitrogen base.
RNA consists of Ribose sugar, a phosphate group, and a nitrogen
base. The main difference between DNA and RNA is in the nucleotide
base in DNA thymine is present and in RNA instead of thymine,
Uracil is present.
