Answer:
Components of DNA includes ribose sugar, phosphate group and four nucleotides(Adenine,cytosine,thymine,guanine).
Step-by-step explanation:
- DNA is made up of two linked strands that are wrapped around each other in a coiled pattern forming the double helix.
- Each strand of the DNA is made of a backbone that consist of a ribose sugar and a phosphate group.
- Each phosphate group is attached to one of the four nucleotides(Adenine,cytosine,thymine,guanine).
- The two strands of a single DNA molecule are linked by the nucleotides.
- Adenine and Guanine are called purines.
- cytosine and Thymine are called pyrimidines.
- Adenine from one strand makes a double bond with Thymine from another strand linking the two strands of DNA molecule.
- Cytosine from one strand makes a triple bond with Guanine from another strand linking the two strands of DNA molecule.
- A picture of DNA and nucleotide structure is attached below.
