What are nucleic acids made up of?
A nucleic acid is a long molecule made up of smaller molecules called nucleotides. Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a new compound from the nuclei of white blood cells.
Why is A nucleic acid A monomer?
Nucleic acids are just groups of nucleotides that bonded together by hydrogen-bonding. So we say that nucleotides are monomers of nucleic acids. A nucleotide is made up of three components, a nitrogenous base, a phosphate (PO3−4) group, and a 5 -carbon sugar.
What monomers make up nucleic acid strands?
Which monomers compose the strands of nucleic acids? Explanation: The strands of nucleic acids are composed of monomeric units called nucleotides. Nucleic acids are mainly the storage sites for genetic information and also have structural and catalytic functions.
What is A monomer of A nucleic acid?
Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.
Is nucleic acid made up of nucleotides?
Nucleotides are the units and the chemicals that are strung together to make nucleic acids, most notably RNA and DNA. And both of those are long chains of repeating nucleotides. There’s an A, C, G, and T in DNA, and in RNA there’s the same three nucleotides as DNA, and then the T is replaced with a uracil.
What monomers make up lipids?
Glycerol and fatty acids are the monomers that make up lipids.
Is nucleic acid a monomer or polymer?
Nucleic Acids – polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group. Carbohydrates – polymers are polysaccharides and disaccharides*; monomers are monosaccharides (simple sugars)
What is the polymer of a nucleic acid?
The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). If the sugar is ribose, the polymer is RNA; if the sugar is the ribose derivative deoxyribose, the polymer is DNA.
What is a lipid monomer?
Glycerol and fatty acids are the monomers of lipids. Lipids include waxes, oils and fats. Let’s take a brief look at how fatty acids are composed. A fatty acid is made of a carboxyl group with a chain of carbons attached.
What kind of nucleic acid is made during transcription?
During transcription, a portion of the cell’s DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.)
What is the monomer and polymer for nucleic acid?
In case of nucleic acids, monomers are the nucleotides composed of nitrogenous base, pentose sugar, and phosphate group whereas DNA and RNA are considered as polymer of nucleic acids. DNA and RNA are composed of monomers termed as nucleotides.
