WebPolymers are very large molecules compared to water. They have many more atoms than a water molecule--from 10,000 to 100,000 atoms per molecule. The word polymer is derived from the Greek root poly-, meaning many, and mer, meaning part or segment. Many of the same units (or mers) are connected together to form a long chain or polymer. WebFeb 22, 2024 · A DNA or RNA is a polymer made of these long chains of nucleotides. Nucleotide comprises a sugar molecule (deoxyribose in DNA or ribose in RNA) attached to a nitrogen-containing base and a phosphate group. There are different bases such as in RNA the base consists of uracil, ...

WebCorrect option is D) DNA and RNA are the polymers of nucleotides which are made up of sugar, the nitrogenous base and phosphate moiety which makes option D correct. DNA and RNA both have four bases; two purines and two pyrimidines, in the nucleotide chains. The purines adenine and guanine and the pyrimidine cytosine are common to both DNA and … WebDNA is the largest macromolecule with a diameter of 2 nm (20Å or 2 x 10-9 m) and often having 3 length in millimetres. It 15 negatively charged due to phosphate groups. It is a long chain polymer of generally several hundred thousands of deoxyribonucleotides. A DNA molecule has two un-branched complementary strands. They are spirally coiled. the mindshaper

WebNucleic acids are biopolymers, macromolecules, essential to all known forms of life. They are composed of nucleotides, which are the monomer components: a 5-carbon sugar, a phosphate group and a nitrogenous base.The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). If the sugar is ribose, the … WebDNA is a polymer of the four nucleotides A, C, G, and T, which are joined through a backbone of alternating phosphate and deoxyribose sugar residues.
