Which of the macromolecules make up chromosomes?

Each chromosome in a eukaryotic cell is made up of DNA which is coiled and condensed around an octamer of basic proteins called histones.

Is chromosome a macromolecule?

The DNA which carries genetic information in cells is normally packaged in the form of one or more large macromolecules called chromosomes.

What are chromosomes mainly made up of?

What is a chromosome? Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).

Is lipid A macromolecule?

Carbohydrates, nucleic acids, and proteins are often found as long polymers in nature. … Lipids are not usually polymers and are smaller than the other three, so they are not considered macromolecules by some sources 1,2start superscript, 1, comma, 2, end superscript.

Is lipid A macromolecule or Micromolecule?

(I) Lipids are macromolecules but obtained under-macromolecular fraction due to their insoluble nature in the aqueous medium of a cell.

What are the chromosomes are mainly made up 3?

Answer: (3)

Each chromosome is made of proteins and a single molecule of deoxyribonucleic acid (DNA). Chromosomes have been defined as bundles of tightly coiled DNA located within the nucleus of almost every cell in our body.

Which are the two main parts that make up a chromosome?

Chromosomes mainly constitute DNA and histone proteins. DNA is wrapped around a core of histone octamer to form a nucleosome. Nucleosomes are the repeating unit present in the chromatin.

What is chromosome made up of Class 9?

Each chromosome is made up of two components (i) Deoxyribonucleic acid (DNA) (ii) Proteins (e.g.; his tones and acidic proteins) These consist of two (unreplicated) or four (duplicated) arms and a primary constriction or centromere which gives them a particular shape due to its position.

Is glucose a macromolecule?

A biological macromolecule is a polymer that occurs naturally in living organisms. Examples of biological macromolecules include carbohydrates and proteins, both of which are essential for life to survive. … Glucose is a carbohydrate monomer. Glucose is the molecule that is needed for cellular respiration.

What macromolecule is triglyceride?

Triglycerides are macromolecules called lipids, better known as fats or oils. Triglycerides are named for the monomer components they contain. “Tri” means three, and triglycerides are built from monomers of three fatty acids bonded to a glycerol.

What macromolecules make up lipids?

Types of biological macromolecules

Biological macromolecule Building blocks Examples
Lipids Fatty acids and glycerol Fats, phospholipids, waxes, oils, grease, steroids
Proteins Amino acids Keratin (found in hair and nails), hormones, enzymes, antibodies
Nucleic acids Nucleotides DNA, RNA

What are the 4 major macromolecules?

11.1 Introduction: The Four Major Macromolecules

These are the carbohydrates, lipids (or fats), proteins, and nucleic acids.

Is nucleic acid a macromolecule?

Nucleic acid is an important class of macromolecules found in all cells and viruses. The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.

What are the macromolecules give example?

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.
