DNA consist of a sugar- phosphate backbone and nitrogenous bases. The Sugar- phosphate backbone is made up of Sugar (deoxyribose) and Phosphate. The nitrogenous base is made up of DNA nucleotides (Thymine, Adenine, Cytosine, and Guanine).
DNA
The DNA molecule has two strands connected by a sugar phosphate backbone.
DNA consists of two strands of nucleotides twisted into a double helix.
DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate.
A DNA molecule has two chains of nucleotides. Each chain is usually referred to as a DNA strand. RNA has only one strand.

DNA
A typical DNA molecule consists of two strands.
A DNA molecule typically consists of two strands.
No, first of in total, both RNA and DNA combined have five nucleotides, DNA and RNA, both consists of three of the same nucleotides, and have one that varies between the two. Both DNA and RNA, have the nucleotides, guanine, cytosine and adenine, however DNA, has the additional nucleotide thymine and RNA instead of thymine has uracil. So, DNA's nucleotides are guanine, cytosine, adenine and thymine, while RNA's are guanine, cytosine, adenine and uracil. To specifically answer the question, no DNA consists of four different nucleotides and RNA consists of three of the same nucleotides, with one differing.
Chromosomes
DNA consists of two strands of nucleotides twisted into a double helix.
The DNA molecule has two strands connected by a sugar phosphate backbone.
Having double stranded DNA means that the DNA molecule consists of two strands that are twisted together in a double helix structure. This is the typical structure of DNA found in living organisms. Single stranded DNA, on the other hand, consists of just one strand of DNA. Double stranded DNA is more stable and less prone to errors during replication compared to single stranded DNA.
The subunits of DNA are known as nucleotides. Each nucleotide consists of a sugar (deoxyribose), a phosphate and a nitrogenous base.
DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate.
DNA stands for Deoxyribo Nucleic Acid. It is double stranded and consists of nucleotides, Phosphoric acid and Ribose sugar. In a chromosome there is the presence of long chain of DNA folded together. If, thus folded DNA is stretched it can be 2-3 m long. Segments of the DNA chain to be precise the groups of base pairs are the gens which governs the characters. Hence, chromosome consists of DNA and in DNA, there is the presence of various types of genes.
