4. Deoxyribonucleotide is a nucleic acid. The building block that form nucleic acid are nucleotides.
5. A nucleotide in DNA is made up of a phosphate, pentose sugar and a base (A,T,G,C)
6. Adenine, thymine, Guanine and Cytosine area the nitrogenous bases found in DNA.
7. DNA is a double helix, it has sugar deoxyribose, phosphate group backbone and it is double-stranded.
8. According to base-pairing rules, percentage of Adenine is equal to Thymine and the percentage of cytosine is about the equal of Guanine.

10. The DNA to the left is replicating via semi-conservative replication because the parent strand is acting as a template for daughter strand.
11. Nucleotide, DNA Chromosome.
Explanation:
DNA is a nucleic acid that stores genetic information of an organism. It is made up of a pentose sugar deoxyribose, phosphoric acids and nucleosides. These together are called nucleotides. Nucleosides are nitrogenous base+pentose sugar.
The four bases present in DNA are two purine bases they are Adenine and Guanine and two pyrimidine bases Thymine and cytosine.
Watson and Crick gave Double-helix structure of DNA. Each strand has an alternating groups of sugar and phosphate. The two bases from the complementary strands are connected via hydrogen bonds. The structure has a key role in replication and protein synthesis.
According to Chargaff rule A+G=C+T
The adenine will always be equal to Thymine and Guanine will always be equal to Cytosine in a DNA molecule.
The DNA base-pairing is complementary as A with T and G with C will pair.
Chromosomes are made up of proteins and DNA, carry genetic information as genes. DNA is made up of nucleotide. A Nucleotide is nitrogenous base+sugar+phosphate group.
The semi-conservative replication is the one in which each daughter strand has one of the parent strands.
