Deoxyribonucleic acid (DNA) carries the genetic instruction for the biological development and functioning of all cellular forms of life. It is the blue print which contains the instructions to construct other cell components. Molecular biology experiments often require isolation of DNA for a variety of purposes like construction of DNA libraries, gene cloning, PCR and other marker technology, etc. The extraction of DNA from actively growing tissue is relatively easier yielding higher quantities of DNA.

Principle

The cell wall is ruptured and the proteins associated with DNA are removed by detergent like SDS or by interaction with phenol. Lipids are extracted with alcohol and DNA is precipitated by isopropanol.

Materials Required

Maize seed samples, Liquid nitrogen, CTAB (Cetyl trimethyl ammonium bromide), Chloroform, isoamyl alcohol, Sodium chloride, Glacial acetic acid, Isopropyl alcohol and 70% ice cold ethanol, TE buffer (5X) (24.2 g of Tris base, 5.71 ml of galcial acetic acid, 10 ml of 0.5M EDTA (pH 8.0) , dissolved in 1000 ml of distilled water). Prepare 1X TE as per the requirement.

Habit & Distribution 
It is a shrub (Fig. 55 a), commonly found in forests and distributed in Central and Southern India.

General Characters
The plant is nearly erect, not twining or climbing. Branchlets are hairy. Leaves are simple, opposite, variable in size up to 18 cm long and 10 cm broad with long pointed end. Flowers are white, fragrant, three forked clusters with flowers stalk of 5 mm long. Berry is mostly simple, 1-1.5 cm long, ellipsoid and black when ripe. The plant flowers during March-May and bears fruits during June-July.

STRAWBERRY

White grubs and cut worms

These insects cut the roots and stems of young plants.
 
Hairy caterpillars

Defoliate plants during June-July

Aim: Bending of the lower half of the ring of Thomas splint to an angle 45- 60degree to comfort the limb and to provide free circulation.

Importance

After tieing the ring with bamboo splint and padding the ring with jute and cotton .bending the lower half of the ring upto more than 45 degree angle is highly essential because of placement of the fractured limb within the ring of Thomas splint comfortably, so as to the flow of blood circulation in fractured limb uninterruptedly.

Herbaceous border

In this system plant are arranged in irregular group of a kind for harmonious are contrasting colour effect, either all flowering at one time or successfully in such a way that those flowering latter should grow up and screen the all ready flowered. The planting of annuals in the border of a plot is called as herbaceous border. When the border is to be viewed from both side tall plant are planted in center followed by medium and dwarf planting in both side. Herbaceous border may include all the herbaceous plant including herbaceous perennial (Flowering and non flowering) bulbous and annuals (see plate 20 & 21).

Nereistoxin (NTX) was originated from a marine annelid worm Lumbriconereis heteropoda and its analogue pesticides (table 51) including cartap, bensultap, thiocyclam and thiobensultap have been commonly used in agriculture, because of their low toxicity and high insecticidal activity.

Whenever the daily maximum temperature exceeds more than average values during summer season the heat wave will occur. Similarly, whenever the daily minimum temperature falls below the average values cold wave will occur. The India Meteorological department has developed the criteria to identify the occurrence the heat waves and cold waves.

11.1 Heat Waves

Heat wave is defined as the condition when the daily maximum temperature is 45ºC or more. Based on departure from normal daily maximum temperature of 40ºC onwards the heat waves are defined as follows:

Common name    :    English- Bellyache bush         
        Hindi- Ratanjoti 
        Odia- Baigoba/Baigewa

Family    :    Euphorbiaceae

Habit & Distribution
It is a shrub (Fig. 56 a), very commonly found in waste ground, village hedges, roadsides and scrub forests. The plant is cultivated and naturalized in several parts of India.

General Characters
The plant is a small dark colored glandular hairy shrub, 0.8-1.8 m in height. The leaves are 6-12 cm in diameter, palmatly 3-5 lobed, entire with 3-5 cm long petiole. Flowers are red with yellow centre. The petioles and stipules have glandular hairs. It flowers and bears fruits during July-October.

When a fixed voltage is applied to two electrodes dipping into a solution,a current will flow, depending on the conductivity of the solution. Conductivity measurements do not give information about the nature of the ions in solution. However, they are useful in the quantitative measurement of the ions.

Abstract

Women play a pivotal role in agriculture, in addition to the traditional role of nourishing progeny as mother and attending to the day to day needs of the home as housewife. Women also add to the family income as wage earners. While comprising half of humanity, contributing to two thirds of the world’s work hours, a woman earns only one third of the total income and owns less than one tenth of the world’s resources.  In a country like India which is the home  for over 400 million women, the economic status of women is in pathetic condition and they have always been discriminated against men in human resource development with  utter disregard to their actual and potential contribution to the national progress in general and agricultural progress in particular. The largest sector of India’s economy, agriculture, contributes to 37 percent of the Gross National Product (GNP) and accounts for 60 percent of the employment.

Aim: To know the actual length of a Thomas splint & measurement for an animal.

Procedure

Animal is kept in lateral recumbancy with affected limb upward.

After padding & medical bending of Thomas splint, it is fitted upon the fractured limb.

At the time of measurement, the limb should be kept vertical to body for accurate measurement, otherwise the length of Thomas splint may be shorteror longer if the limb is kept forward or backward respectively.

The ring of the Thomas splint is kept close to the axilla (forelimb), groin (hind limb).

Limb is put downward & Thomas splint is pushed upward keeping both the extension bamboo of Thomas splint in crossed manner, measurement of length of Thomas splint is taken up to the bulb of the heel & mark is recorded.

The excess length is trimmed short (figure-1). Two nicks are made on the distal end for retaining the thread in position.

Both the distal ends are tied together with thread, soft padding is placed at the site where hoof is to be kept & retained in position with bandage (figure-3).

Agarose gel electrophoresis is used for the fractionation and characterization of nucleic acids. It is a simple and highly effective method for separating, identifying and purifying DNA fragments of various sizes. DNA can be checked for size, intactness, homogeneity and purity by this technique. Agarose is a purified form of agar and forms a gel by hydrogen bonding of the agarose monomers. Increasing the Agarose concentration of a gel reduces the migration speed and enables separation of smaller DNA molecules. Shorter molecules move faster and migrate further than longer ones.

Aim: To study the size of the DNA extracted from the fungal culture.

Principle: Ethidium Bromide added to the gel interacts with the bases of DNA and fluorescence orange when irradiated with UV light.

Fungi are achlorophyllus so they have to depend on other organisms hence heterotrophic nutrition. Depending on the nutrition, fungi are classified as Saprophytes, Parasites and Symbionts.

3.1 Saprophyte (sapros = rotten; phyton = plant)

Fungi which get their nutrition only from dead organic are called saprophytes ex: Saprolegnia, Rhizopus, Mucor, Alternaria etc.

3.1.1 Facultative saprophyte (Facultas = ability)

Ability of a fungus to become saprophyte. It is a parasite ex. Ustilago

3.1.2 Obligate saprophyte (obligate = to bind itself)

When they strictly get their food only from dead organic matter and can never become parasites are called obligate saprophyte ex. Mucor.

Slugs and snails occasionally cause serious damage to seedlings, tender, lowgrowing leafy vegetables; or ripening fruit that are on the ground. Feeding damage, hollowed-out areas, can be found anywhere on fruit, but is usually concentrated near the stem. Slugs leave a tell tale slime trail (silvery trail) behind on the surface of fruit or leaves.
