  1. Molecular cloning

  2. Tissue culture

  3. Protoplasmic fusion

  4. Splicing

Show answer
Correct Option: A

The technique in which the developing embryo (at definite stage) from a pregnant superior breed is removed and transferred to another female with inferior characters, in whose body further development till birth takes place. Such technique is called as

zoology applications of biotechnology cloning process of cloning gene cloning

  1. Embryo transfer

  2. Artificial insemination

  3. Protoplast fusion

  4. Cloning

Show answer
Correct Option: A
Explanation:

  • Embryo transfer is the technique in which the developing embryo from a pregnant superior breed is removed and transferred to another female with inferior characters for establishing the pregnancy and in whose body further development takes place till birth. It is used in humans as well as animals.

So, the correct answer is 'Embryo transfer'.

Offsprings formed by asexual reproduction exhibit remarkable similarity. This is known as

zoology applications of biotechnology cloning process of cloning gene cloning

  1. Clone

  2. Gamete

  3. Androecium

  4. Gynoecium

Show answer
Correct Option: A
Explanation:

Cloning is the production of identical genetic copies. All forms of asexual reproduction are variations of the cell division process of mitosis. Asexual reproduction is sometimes called as cloning and the individual copy produced by cloning method is called as a clone.

The nucleus of a donor embryonal cell/somatic cell is transferred to an enucleated egg cell. Then after the formation of an organism, what shall be true?

zoology applications of biotechnology cloning process of cloning gene cloning

  1. Organism will have extranuclear genes of the donor cell

  2. Organism will have extra nuclear genes of recipient cell

  3. Organism will have extra nuclear genes of both donor and recipient cell

  4. Organism will have nuclear genes of recipient cell

Show answer
Correct Option: B
Explanation:

It is given that the recipient cell has  been enucleated. It means its nucleus or genetic material has been removed. Hence, the organism that will develop from it would have the nuclear genes of donor embryonal/ somatic cell. Hence, the organism will have extra nuclear genes of recipient cell. 

Thus, the correct answer is 'Organism will have extra nuclear genes of recipient cell.'

'Clones' are individuals that have exactly the same ________.

  1. Lifespan

  2. Physiology

  3. Growth rate

  4. Genetic makeup

Show answer
Correct Option: D

Cloning of animals has been possible due to advances in

zoology applications of biotechnology cloning process of cloning gene cloning

  1. nuclear technology

  2. computer technology

  3. biotechnology

  4. autoradiography

Show answer
Correct Option: C
Explanation:

Cloning in biotechnology refers to the process of creating clones i.e. exact copies of an organism. Biotechnology is technology that utilizes biological systems, living organisms or parts of this to develop or create different products. Due to the advancement of biotechnological processes like DNA cloning, amplification, isolation, recombination etc. It has been possible to create clones of animals. 

So, the correct option is 'biotechnology.'

Population of cells derived from a single parent cell is called

zoology applications of biotechnology cloning process of cloning gene cloning

  1. Symmetrical cell

  2. Diploid

  3. Haploid

  4. Clone

Show answer
Correct Option: D
Explanation:
Clone are cells or organism that is genetically identical to the original cell or organism from which it is derived. Many unicellular organisms, such as bacteria and yeasts, are clones of parent cells generated by either binary fission or budding. The body cells of plants and animals are clones ultimately derived from the mitosis (cell reproduction) of a single fertilized egg. More narrowly, a clone can be defined as an individual organism that was grown from a single body cell of its parent and that is genetically identical to it.
So the correct option is 'clone'.

A large number of bacteria produced from a single bacterium is called as 

zoology applications of biotechnology cloning process of cloning gene cloning

  1. Deme

  2. Population

  3. Clones

  4. Offspring

Show answer
Correct Option: C
Explanation:
Cell clones can form by cell division from a single transformed cell and be propagated to produce a large number of cells with an identical foreign DNA molecules that we wish to clone into the cells, a process known as transformation. Amplification process produces a huge number of identical bacterial cell clones, each with the same foreign DNA sequence.
Therefore, the correct answer is option C.

'Cloning' is meant 

zoology applications of biotechnology cloning process of cloning gene cloning

  1. For production of HGH gene is E. coli

  2. To preserve the genotype of organism

  3. To replace the original gene

  4. All of the above

Show answer
Correct Option: B
Explanation:
The clone is a population of cells or individuals which are genetically similar to the donor cell or individual. It can be performed by using the complete organisms or the cells from the single parent through the method of asexual reproduction. Its main purpose is to preserve the genotype of an organism. The cloning is of two types namely: 
i. Gene cloning at the molecular level and
ii. Cloning of the organisms.
Thus, the correct answer is option B.

Two offsprings having the same genetic material and the same body features, produced by one parent through asexual reproduction, are called as
