Question

What makes up the sides of a DNA molecule? Question 4 options: phosphates and ribose sugar bases and deoxyribose sugar phosphates and deoxyribose sugar

Answer 1

Answer:

Phosphates and deoxyribose sugar makes up the sides of a DNA molecule.

Explanation:

• DNA is the storage for the gene and hereditary information in an organism that has the double helix structure.
• DNA ladder is compromised of the sequential alteration of phosphates and sugar.
• Deoxyribose is the sugar that is found on the side and between them lies the nitrogen bases A T C G (adenine , thymine , cytosine , and guanine ).

Answer 2

DNA is the genetic material that codes for proteins vital for cell functioning and signals. They get inherited from the parents to their offspring via reproduction methods.

Phosphates and deoxyribose sugar construct up the sides of a DNA molecule.

What is DNA composed of?

• DNA is composed of a hexose sugar molecule called deoxyribose,  inorganic phosphates groups and nucleotide bases of purines and pyrimidines.

• The nucleotide bases are seen on the inside of the helical structure of the molecule while the sugar and the phosphates are on the sides of the molecules.

Therefore, option c. phosphates and deoxyribose sugar are correct.
