  • Nucleus of human body cell contains about 20,000 genes, half of which being contributed by each parent
  • Term gene was coined by Johannsen in 1909
  • DNA = Deoxy ribose nucleic acid
  • RNA = Ribose nucleic acid
  • Histones are on chromosomes
  • Chromosomes word was coined by Waldeyer in 1888
  • Number of chromosomes in human being is 46
  • Chromosomes in spermatozoa are 23
  • Smallest part of a gene is Mutton
  • Mitochondria are power house of cells
  • Golgi bodies are involved in cell secretions
  • Ribosome are rich in DNA and prepare protein
  • Plastids are found in Plant cells only and contain chlorophyll
  • Centrosomes help in cell division
  • Proteins are synthesized by Golgi bodies.
  • Cellulose respiration is done by Mitochondrion
  • Light energy is stored in the form of chemical energy due to the activity of Chloroplast.
  • Protoplasm is a colloidal solution.
  • Most cells are microscopic but the egg cell of an ostrich is 15-20 cm long and some giraffe nerve cells reach more then 4 m long
  • Mitochondria do work of cell respiration.
  • The nucleus, mitocondria and chloroplast have double membranes
  • Bacteria have no nucleus and no mitochondria they have just a single loop of DNA cell nucleoid as well as food granules and ribosome which produce proteins
  • Each cell has the same set of about 30,000 genes.
  • Genes are arranged along a long and thin thread-like structure called chromosomes.
  • Snakes have 36 chromosomes, horse has 63 while some ferns have 500 or more
  • Humans have a total of 46 chromosomes- 23 pairs in every cell. The only exception are sperm and egg cells which have 23 unpaired chromosomes.
  • Genes are made of a chemical called deoxyribonucleic acid or DNA
  • DNA tells a cell how to make the proteins
  • Every cell in a body contains at least 10,000 different kinds of proteins.
  • The machinery for making these proteins is on structures called ribosome which are outside the nucleus.
  • RNA carries the instructions for making a particular protein to the ribosome.
  • A permanent change to a piece of DNA is called a mutation.
  • Nearly a third of a human being’s genes are the same as the genes of a lettuce.
  • DNA is shaped like a twisted ladder called double helix. The rungs of the ladder are made up of four chemical building blocks Adenine, Guanine, Thymine, and Cytosine
