what are the subunits of nucleic acids such as dna and rna?

Nucleic acids (DNA, RNA) are large polymers, made out of monomer building blocks called nucleotides. The nucleotides have a similar structure with three 'subunits': A phosphate group. ... A nitrogenous base : adenine, cytosine, guanine, thymine or uracil.

​Nucleotide RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).

I think the simplest unit of a nucleic acid is a nucleotide. It is an organic molecule that serve as the monomer of nucleic acid such as DNA and RNA. It is referred to as the building block of nucleic acid and is composed of a nitrogenous base, a five carbon sugar and at least one phosphate group.

A nucleic acid is an organic compound, such as DNA or RNA, that is built of small units called nucleotides. Many nucleotides bind together to form a chain called a polynucleotide. The nucleic acid DNA (deoxyribonucleic acid) consists of two polynucleotide chains.

However, unlike DNA, RNA is usually a single-stranded molecule. Also, the sugar in RNA is ribose instead of deoxyribose (ribose contains one more hydroxyl group on the second carbon), which accounts for the molecule's name. RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine.

The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell's activities, while RNA converts that code into proteins to carry out cellular functions.

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. ... DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans.

DNA and RNA are two different nucleic acids found in the cells of every living organism. They both each have significan roles to play in cell biology. 2) ﻿DNA also has uracil as its base while the DNA base is thymime. 3) DNA is composed of deoxyribose sugar while RNA is made up of ribose sugar.

Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: Nitrogenous Base. Purines and pyrimidines are the two categories of nitrogenous bases. ...

Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three components: a purine or pyrimidine nucleobase (sometimes termed nitrogenous base or simply base), a pentose sugar, and a phosphate group.

DNA is a double-stranded molecule, while RNA is a single-stranded molecule. ... DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine.

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U).

RNA is somewhat similar to DNA; they both are nucleic acids of nitrogen-containing bases joined by sugar-phosphate backbone. How ever structural and functional differences distinguish RNA from DNA. Structurally, RNA is a single-stranded where as DNA is double stranded. DNA has Thymine, where as RNA has Uracil.

There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are composed of nucleotides. ... DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous base thymine, while RNA contains the nitrogenous base uracil. The diagram below shows the structure of a DNA nucleotide.

Each nucleotide consists of a heterocyclic base linked via a five-carbon sugar (deoxyribose or ribose) to a phosphate group (see Figure 4-1). DNA and RNA each contain four different bases (see Figure 4-2). The purines adenine (A) and guanine (G) and the pyrimidine cytosine (C) are present in both DNA and RNA.

As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA is a single-stranded nucleic acid. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
