Ans.

Dideoxyribonucleotide chain termination method is a method of DNA sequencing, by which the order of nucleotide present in a DNA molecule, can be identified. This method was developed by Sanger that involves use of dideoxyribonucleotides (nucleotide that lack both 2' and 3'-OH groups).

The chain termination method is based on the selective incorporation of dideoxynucleotides during in vitro DNA replication of that gives idea about sequence of DNA of interest.

Thus, the correct answer is option B). 'sequencing DNA.'

Explanation:

- The cell is the simplest, basic and functional unit of life.

- Tissue is a collection of similar cells e.g brain tissue

- Organ is a collection of similar tissues e.g Liver, Lungs

- Organ system refers to a group of closely related organs performing the same function in an organism.

- Organism comprises of well-coordinated organ systems.

- Population refers to the total number of organisms living and breeding together.

Answer to Question 2

Cell --> Genome --> Gene --> Nucleotide

Explanation:

A cell consists of a nucleus and other organelles. Within the nucleus & other organelles like mitochondria lies the total genetic material of the cell known as GENOME.

- The genome contains several functional sequence of bases known as GENE.

- A gene is made of triplets of nucleotides (codons)
