These are very fine thread-like, coiled filaments uniformly distributed in the nucleoplasm. At the time of cell division, the chromatin becomes thick and ribbon like and are known as chromosomes. The chromosomes contain genes, which are composed of DNA (deoxy-ribonucleic acid). Genes are responsib..

A source of emf is connected across one pair of opposite junctions (A and C), and a galvanometer G across the other opposite pair (B and D). The key K 1 is closed first and then K 2 . The value of R is varied till the galvanometer shows no deflection, i.e., I g = 0. Then, the..

Aromatic hydrocarbons are called arenes. When one or more hydrogens are removed from the aromatic hydrocarbons, the residues left behind are termed as aryl groups (similar to alkyl groups in the case of aliphatic hydrocarbons). The aryl groups are represente..

The univalent hydrocarbon unit derived from an alkane by the loss of one hydrogen atom is termed as alkyl group. Thus, an alkyl group ay be represented by the general formula C n H 2 n + 2 and denoted by R (an alkane is denoted as RH). The alkyl groups..

In many electrical circuits, capacitors are to be grouped suitably to obtain the desired capacitance. The two most common modes are: 1. Capacitors in series 2. Capacitors in parall..

. There are two types of antibodies, corresponding to the types of antigens. The two antibodies are: antibody a antibody b Anti-body a reacts to the antigen A and antibody b reacts to the antigen b. Thus, the blood of A group that contains antigen A will contain antibody b and not antibod..

When a molecule contains more than one similar functional groups, then, the word di (for 2), tri (for 3), etc., is added before the secondary suffix, of the functional group. While adding such words, the vowel 'e' of primary suffix is retained. For example: ..

Root word: but C=O preferred over the OH group (so lowest number) Prefixes are: methyl and hydroxy Primary suffix: ane Secondary suffix: one Name of the compound is: 3-hydroxy-3-methylbutan-2-one..
