Which type of nucleotide contains a base, a monosaccharide, and a phosphate group?

Ribonucleotide

What is the significance of the hydrogen bonds in DNA and RNA?

They provide stability to the double helix structure.

Which of the following statements accurately reflects the role of NAR (Nucleic Acid of Ribonucleotide)?

NAR serves as the primary molecule for the storage and transmission of genetic information in cells.

What did scientists in the late nineteenth century believe about the molecules within the nucleus related to heredity?

They believed that the molecules within the nucleus actively controlled heredity and genetic traits.

What is the significance of identifying the structure of NAR (Ribonucleic Acid) within the nucleus?

It helps in unraveling the mysteries of gene regulation and expression.
