DNA is made of two strands (chains) of DNA nucleotides that are twisted, forming a double helix, often compared to a twisted ladder. The two strands are held together by hydrogen bonds between the nitrogen bases.

Why RNA and dna termed nucleic acids?

RNA and DNA are nucleic acids because they are composed of chains of nucleotides, which make up nucleic acids.


Nucleic acids are long chains of amino acids?

Actually, nucleic acids are long chains of nucleotides, not amino acids. They are the building blocks of DNA and RNA, carrying genetic information in the form of sequences of nucleotides. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

What substances make up DNA?

DNA is made up of four types of nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). These nucleotides form long chains that combine to create the genetic code that determines an organism's traits.


Are genes are made up of smaller molecules known as chromosomes?

Genes are segments of DNA, not smaller molecules like chromosomes. Chromosomes are long chains of DNA that contain multiple genes. Genes are specific sequences of DNA that encode information for making proteins, while chromosomes are structures that help organize and package the DNA in the cell.

What are the two long chains in the DNA called?

The two long chains in DNA are called nucleotide strands. These strands are made up of smaller units called nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. The nucleotide strands are complementary and form a double helix structure.
