- Recognizes the triplet codon present in the m RNA
- Base sequence of anticodon arm – complementary to base sequence of mRNA codon
- Due to complimentarity it can bind specifically with mRNA by hydrogen bonds
- A hydrometer is an instrument used to measure the specific gravity or relative density of liquids, i.e. the ratio of the density of the liquid to the density of water.
- Hydrometers are usually made of glass and consists of a cylindrical stem and a bulb weighted with a heavy material to make it float upright.
- Fermentation occurs in yeast cells and bacteria and also in the muscles of animals. It is an anaerobic pathway in which glucose is broken down.
- The respiration that happens at the minute level in our body, viz., in the cell is called the cellular respiration.
- It occurs in the presence or absence of oxygen.
- Any type of cellular respiration begins with glycolysis where a 3-C molecule, pyruvic acid is formed as the end product.
- Cycas leaves are dimorphic and show habitual heterophylly.
- The two types of leaves are scale leaves and foliage leaves.
- Foliage leaves are spirally borne on a terminal crown.
- These are unipinnate and paripinnate compound and fairly large.
- These are attached to the stem by rhomboidal leaf bases.
- It has stout rachis on whose lateral side 50-100 pairs of leaflets are arranged.
- Each leaflet is sessile, straight, linear-lanceolate .

Rickets is a disease that mainly affects children with vitamin D deficiency. It is also caused by a lack of calcium and phosphorus. Vitamin D deficiency is a disease in which the bones (bones) become soft and weak. Curved bones in the legs and small bell-shaped tumours on the ribs are common symptoms in children with cataracts.

March 24 is World Tuberculosis Day. This day is celebrated since 1992. Effective medicine and vaccine for tuberculosis have been available for more than fifty years.
-
Prevention and control efforts against tuberculosis are ongoing throughout the world.
-
But tuberculosis remains the world’s number one killer even today.
- Immunoglobulin M (IgM) is also one of the first antibodies recruited by the immune system to fight infection.
- IgM populations rise very quickly when the body is first confronted with an infectious organism, and then they plummet as IgG antibodies take over.
- IgM is also produced by B cells and, when bound to a pathogen, will spur other antibodies and immune cells into action.
- Allergic reactions are the result of the production of specific IgE antibody to common, innocuous antigens.
- Allergens are small antigens that commonly provoke an IgE antibody response.
- Cross-linking IgE bound to its receptor on cells by multivalent allergens initiates a chain of events resulting in allergic immune responses.
- Monoclonal antibodies are used widely in research and diagnostics.
- They are used in various clinical situations, such as treatment of cancer and autoimmune diseases.
- They are used in inducing immune suppression in transplant surgery, and in the prevention of infectious diseases.
