The first ________ was given in 1990 to a 4-year old girl with adenosine deaminase (ADA) deficiency.

Read the passage carefully and answer the given questions.
Recombinant DNA Technology
Asexual reproduction preserves the genetic information, while sexual reproduction permits variation. Traditional hybridization procedures used in plants and animals breeding very often lead to inclusion and multiplication of undesirable genes along with the desired genes. The techniques of genetic engineering, which include creation of recombinant DNA, use of gene cloning and gene transfer, overcome this limitation and allow us to isolate and introduce only one or a set of desirable genes without introducing genes into the target organism.
In Recombinant DNA Technology, what is the role of the "selectable marker gene"?

Baculoviruses are -

Which enzyme is used to join DNA fragments during recombinant DNA formation?

Study the human pedigree chart given below and choose the correct
conclusion.

Which one of the given assisted reproductive technologies (ART) involves transfer of fertilized egg into the fallopian tube?

Identify the incorrect feature of human genome.

A plane electromagnetic wave of frequency 75 Hz travels in free space along the X -direction. At a particular point in space and time \(\vec{E}=9.6 \hat{j}\). What is \(\vec{B}\) at that point ?
( \(E=\) Electric field, \(B=\) Magnetic field)

Arrange the given steps involved in gel electrophoresis used for separation of DNA fragments?
(A) Exposure to UV light
(B) Staining with ethidium bromide
(C) Movement of DNA fragments towards anode
(D) Elution
Choose the correct answer from the options given below:

A cell supplies a current of 0.6 A through a 3 \( \Omega \) resistor and a current of 0.2 A through a 10 \( \Omega \) resistor. The internal resistance of the cell is :

Value of \(\int \frac{2}{(x-3) \sqrt{x+1}} d x\) is : (Here \(C\) is an arbitrary constant)

If the temperature of a metallic conductor is increased, then the product of resistivity and conductivity

From a container full of orange juice, 7.5 liters was drawn out and replaced by soda water.
This process is repeated 5 more time.
The ratio of quantity of orange juice and soda water left in the container is 4:5.
How much liter of orange juice did the container originally had?
(Use \((0.44)^{1 / 6}\) = 0.802)
