A cloning vector is a small piece of DNA, taken from a virus, plasmid, or the cell of a higher organism, into which a foreign DNA segment can be inserted for cloning purposes. The options provided are:
The Probe is not a cloning vector because it serves a different purpose, primarily used for hybridization experiments to detect the presence of complementary nucleic acid sequences.
A probe is not a cloning vector. It is a short, labeled DNA or RNA molecule used to detect the presence of a complementary sequence in a sample, typically for molecular biology techniques like hybridization. Cloning vectors, on the other hand, are used to carry and replicate foreign DNA fragments in host organisms for various purposes in genetic engineering and molecular biology.
YAC (Yeast Artificial Chromosome), pBR322, and BAC (Bacterial Artificial Chromosome) are examples of cloning vectors.
so, the correct option is (C): Probe
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
Predict the major product $ P $ in the following sequence of reactions:
(i) HBr, benzoyl peroxide
(ii) KCN
(iii) Na(Hg), $C_{2}H_{5}OH$
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
Enzymes are proteins that help accelerate metabolism or the chemical reactions in our bodies. They build some substances and decompose others. All living creatures have enzymes.
Our bodies naturally build enzymes. But enzymes are also in mass produce products and food.
One of the most important roles of enzymes is to succor digestion. The process of turning the food that we eat into energy is called digestion. For instance, there are enzymes in our saliva, pancreas, stomach, and intestines. They decompose fats, proteins, and carbohydrates. Enzymes make use of these nutrients for growth and cell repair.
