Image
CHAPTER 6: MOLECULAR BASIS OF INHERITANCE Search for genetic material and DNA as genetic material; Structure of DNA and RNA; DNA packaging: DNA replication; Central dogma; transcription, genetic code, translation; gene expression and regulation lac operon; genome and human and rice genome projects; DNA fingerprinting. Anticodon: A sequence of three nitrogenous bases on tRNA which is com plementary to the codon on mRNA. Genome : Sum total of genes in haploid set of chromosomes. DNA Polymorphism: The variations at genetic level, where an inheritable mutation is observed, in a population at high frequency. Satellite DNA: The repetitive DNA sequences which form a large portion of genome and have high degree of polymorphism but do not code for any proteins. Operon: A group of genes which control a metabolic pathway. Exons: The regions of a gene which become part of mRNA and code for  different regions of proteins. Introns: The regions of a gene which ...

NEURAL CONTROL AND COORDINATION Coordination: Process through which two or more organs interact and  complement the functions of one another surrounding the brain.  Action potential: A sudden change in the electrical charges in the plasma  membrane of a nerve libre. Aqueous humour: The thin watery fluid that occupy space between lens  and cornea in eye. Blind spot: A spot on retina which is free from rods and cones and lack the ability for vision. Cerebrospinal fluid: An alkaline fluid present in between inner two layer of meninges, surrounding the brain and spinal cord. Cerebellum: A part of hind brain that controls the balance and posture of  the body. Cochlea:  A spirally coiled part of internal ear which is responsible for hearing. Corpus callosum: A curved thick bundle of nerve fibres that joins two  cerebral hemisphere. Depolarisation: A condition when polarity of the plasma membrane of  nerve fibre is reversed.  Endolymph: The fluid f...
