What are the macromolecules made of?
Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules. Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.
What are macromolecules and give examples?
Macromolecules are large complex molecules present in colloidal state in intercellular fluid. They are formed by the condensation of low molecular weight micromolecules and hence are polymeric in nature. Polysaccharides, proteins, and nucleic acids are common examples of macromolecules.
What are the 5 macromolecules?
Biological macromolecules, the large molecules necessary for life, include carbohydrates, lipids, nucleic acids, and proteins.
What is the monomer found in proteins?
What is a monomer of DNA?
The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.
What are the different types of monomer that make up DNA?
All nucleic acids are made up of the same building blocks (monomers). Chemists call the monomers “nucleotides.” The five pieces are uracil, cytosine, thymine, adenine, and guanine. No matter what science class you are in, you will always hear about ATCG when looking at DNA.
How many different monomers are there in DNA?
four different monomers
What are the two components of the backbone of DNA?
DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T).
What are the four nitrogen bases contained in DNA?
There are four different DNA nucleotides, each defined by a specific nitrogenous base: adenine (often abbreviated “A” in science writing), thymine (abbreviated “T”), guanine (abbreviated “G”), and cytosine (abbreviated “C”) (Figure 2).
What is the complete name of DNA?
