Nucleotides

Science > Biology > Gene its Nature, Expression and Regulation > Nucleotides In this article, we shall study structural units of nucleic acid called nucleotides. In 1869, Friedrich Miescher separated cellular substance from the nuclei of pus cell and called it ‘Nuclein’. Due to acidic nature, the substance is further called as nucleic acid. There are […]

Genetic Material

Science > Biology > Gene its Nature, Expression and Regulation > Genetic Material DNA as Genetic Material Griffith Experiment: Background: Meischer isolated nuclein from nuclei of WBCs in 1869. Walter Sutton, Thomas Hunt Morgan established that the hereditary material lies in the nucleus in chromosomes. Chromosomes are formed of proteins and nucleic acid, DNA. For […]

Types of Genes

Science > Biology > Gene its Nature, Expression and Regulation > Types of Genes In the last article, we have studied the meaning of the term gene. In this article, we shall study types of genes. Based on the function and activity, the genes are classified as follows. Housekeeping Genes or Constitutive Genes: Housekeeping genes […]

No Comments on Mendel’s Laws of Inheritance

Science > Biology > Genetic Basis of Inheritance > Mendel’s Laws of Inheritance The first scientific explanation of inheritance was given by Mendel in 1866. He performed a series of experiments on garden pea in a scientific manner and proposed rules. which are called as Mendel’s Laws of Inheritance. His work is known as Mendelism. He laid […]

Polygenic Inheritance

Science > Biology > Genetic Basis of Inheritance > Polygenic Inheritance Mendel performed his experiments with garden pea plant, which has traits or alleles having complete dominance and hence the laws of inheritance were proved. Other scientists performed their experiments on different plants and animals and found deviations to Mendelian ratios. Depending upon these experiments and […]
