Question

Describe the relationship between DNA, chromosomes, and genes.

Answer 1

Paraphrased answer:

The structures present in the nucleus of cells are called chromosomes. Genes make up chromosomes, which are made up of DNA. Deoxyribonucleic acid (DNA) is an abbreviated form. The nucleotides make up DNA. Nucleotide bases, sugar, and phosphate may all be separated from these nucleotides. Genes are physical and functional units of hereditary information.

Answer 2

Genes are DNA segments that contain the code for a specific protein that functions in one or more types of cells in the body, and genes are found in chromosomes, which are found in the nucleus of the cell.

Chromosomes:

• A chromosome is a long DNA molecule that contains some or all of the genetic material of an organism.
• Histones, which bind to and condense the DNA molecule to maintain its integrity, are found on the majority of eukaryotic chromosomes.
• In the nucleus of each cell, the DNA molecule is packaged into thread-like structures known as chromosomes.
• Chromosomes are DNA-carrying structures found in the center of cells (the nucleus).
• DNA is the material that contains genes.
• Chromosomes also contain proteins that aid in DNA formation.

DNA:

• Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix that contains genetic instructions for all known organisms and viruses' development, functioning, growth, and reproduction.
• DNA and ribonucleic acid are examples of nucleic acids.
• DNA is the information molecule.
• It contains instructions for the synthesis of larger molecules known as proteins.
• These instructions are stored in each of your cells and are spread out over 46 long structures known as chromosomes.
• These chromosomes are made up of thousands of shorter segments of DNA known as genes.

Genes:

• The most fundamental physical and functional unit of heredity is the gene.
• The building block of genes is DNA.
• Some genes act as blueprints for protein synthesis.
• However, many genes do not encode proteins.
• Human genes range in size from a few hundred to over 2 million DNA bases.
