The molecular mechanism by which a gene shows to potential in the phenotype of an organism, is called gene expression. Every gene contains the blue print required for the function of a given polypeptide, in the form of a specific sequence of nucleotides. The transfer of a code present in th..

>Peptiglycons are found in the cell walls of prokaryotic cells. Proteins are polymers of aminoacids arranged in a specific sequence which is decided by the genetic code present in the DNA molecule. The polypeptide chain in a protein may be straight (primary structure) or may form helical ..

>Mitosis occurs in all the living cells of the body of an organism. Hence it is called somatic cell division. Mitosis is described as equational division since the chromosome number of daughter cells will be same as that of the parent cell. Mitosis has an interphase, karyokinesis and cytokinesis. I..

>The homeostatic mechanisms work on a negative feedback. In order to ensure the continuation of species, all living organisms exhibit reproduction. The entire cellular information is stored in the DNA which undergoes replication to transfer the information to the successive generations. T..

>Some hormones such as steroid hormones act by binding to DNA and attering gene expression. Other hormones bind to membrane receptors, where they either open ion channels (usually Ca + + ) or trigger production of other chemical messengers inside the cell. Typically the receptor activates..

. Chromatin network is formed by the long and coiled DNA molecule and histone proteins. The chromatin network condenses into chromosomes at the time of cell division. Nucleolus is composed of ribosomes and RNA. Nucleus is the controlling centre of the cell. It is also involved in the tran..

) to the active living bacterium (recipient), which expresses the character of the donor cell, and so is called a recombinant. Mixture Result R-Type Bacteria + Carbohydrates of S-Type Bacteria R-Type Bacteria R-Type Bacteria + Protein of S-Type Bacteria R-Type Bacteria R-Type Bacteria + DNA..

Summary - Chromosomes are tiny thread-like structures found in the nucleus of a cell. Chromosomes store and transmit the coded information which is responsible for all the life processes of an organism. Hence, chromosomes are commonly described as carriers of heredity. In bacteria, the en..
