What are the major chemical components of chromosomes?
The major chemical components of the chromosome are DNA, RNA (nucleic acids), and proteins (histones and nonhistones).
What are the components of a chromosome?
The components of eukaryotic chromosome are DNA, RNA, histone, and non-histone protein, metallic ions, etc. The DNA is the most stable molecule carrying out transfer of genetic information from one generation to the other.
What is the chemical unit of chromosome?
The unit of the chromosome is the gene. A gene is a DNA segment that carries information from parents to children and determines the heredity characters in the offspring.
What is the primary chemical component of chromosomes and genes?
DNA (deoxyribonucleic acid) is the cell’s genetic material, contained in chromosomes within the cell nucleus and mitochondria.
What are the two main components of chromosomes?
The main components of chromosomes are DNA and proteins.
What is chemical composition of gene?
Genes are made of nucleic acids, linear molecules consisting of a string of four nucleotides, which, in deoxyribonucleic acid (DNA), are adenine (A), thymine (T), guanine (G) and cytosine (C).
What are the components of chromosome class 10th?
Chromosomes consist of DNA, histone proteins, non-histone proteins, metallic ions and also some RNA. Chromosomes are called so because they readily absorb certain basic dye stains and can be visualised as dark stained material.
What is the name of the chemical substance which constitutes the genes?
DNA is the chemical name for the molecule that carries genetic instructions in all living things. The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix.
What are the 23 chromosomes called?
The first 22 pairs of chromosomes are called autosomes. The 23rd pair of chromosomes are known as the sex chromosomes, because they decide if you will be born male or female. Females have two X chromosomes, while males have one X and one Y chromosome.
Which of the following chemicals is a component of eukaryotic chromosomes?
Eukaryotic chromosomes consist of a DNA-protein complex that is organized in a compact manner which permits the large amount of DNA to be stored in the nucleus of the cell. The subunit designation of the chromosome is chromatin. The fundamental unit of chromatin is the nucleosome.
What is chromosome morphology?
Chromosome morphology can assign specific groups to specific chromosomes, and for favorable species, genes to a specific chromosome arm. The chromosomes of most fungal species, however, are notoriously small and difficult to count.
