Characteristics of Genetic Code
The genetic code is a triplet code: Three adjacent bases, termed as codon, specify one amino acid Non-overlapping: Adjacent codons do not overlap. No punctuation: The genetic code is comma less. The genetic code is universal i.e., a given codon specifies the same amin..
Biomolecules
Biomolecules are complex organic molecules. These molecules form the basic structural constituent of a living cell. The organic compounds such as amino acids, nucleotides and monosaccharides serve as building blocks of complex biomolecules. The important biomolec..
Matrix
Matrix of blood is known as plasma. Nearly 90% of the plasma is represented by water. The organic substances account for about 9% and the remaining 1% is represented by inorganic substances. The organic substances in the plasma occur in a wide variety of forms. There are carbohydrates mos..
Nitrogen fixation
The different steps involved in nitrogen fixation are as follows: 1) Atmospheric nitrogen is reduced by the addition of hydrogen atoms. 2) As a result the there bonds between the two nitrogen atoms are broken down resulting in the formation of ammonia. 3) Nitrogen fixation thus requires the followi..

Sulphur occurs in the earth's crust to the extent of 0.05% mostly as metal sulphides and sulphates. It also occurs in the elemental form in large underground beds. Another major source of sulphur is H 2 S present in the natural gas and crude oil. Sulphur exists in combined state in ..
Preparation
Nylon-66 is obtained by the condensation polymerization of adipic acid and hexamethylene diamine. The carboxyl group [-COOH] of the adipic acid reacts with the amino group [-NH 2 ] of hexamethylene diamine and forms a long-chain amide [-CO-NH] structure with..

Leading Strand - The enzyme forms one new strand in a continuous stretch in the 5'-3' direction and is called leading strand. On the other parent strand, the enzyme forms short stretches of DNA once again in the 5'-3' direction starting from an RNA primer. These s..

Amines are formed by replacing one or more hydrogen atoms of ammonia (NH 3 ) with alkyl groups. These are further classified as primary, secondary and tertiary amines according to one, two or three hydrogen atoms of ammonia being replaced by alkyl groups. For example, Primary (aminoh..

The rRNA molecule is greatly coiled. In combination with proteins, it forms the small and large subunits of the ribosomes, hence its name. It forms about 80% of the total RNA of a cell. A eukaryotic ribosome is 80S; with a large 60S subunit consists of 28S, 5.8S and 5..
