Identify the correct process of protein synthesis from DNA-
DNA mRNA Protein
According to the Central Dogma of molecular biology: DNA mRNA Protein.
Which of the following nitrogenous bases is not related to DNA?
DNA contains Thymine, whereas Uracil is found only in RNA.
Phenylketonuria is an autosomal recessive disorder in humans. If the frequency of affected newborns is 1 in 14000, assuming random mating, what will be the frequency of heterozygotes?
According to the Hardy-Weinberg equation, . Therefore, . Since , . The frequency of heterozygotes is .
What is sudden genetic change in life called? [LDC - 19.08.2018]
The sudden and inheritable change occurring in the DNA of organisms is called 'mutation'. Mutation was discovered by Hugo de Vries.
Which of the following is a transgenic animal?
The organism created from the embryos of sheep and goat, which is a hybrid breed of sheep and goat, is called GEEP, in which cells of both goat and sheep are present.

Mendel's Law of Independent Assortment is based on the observations of- [RPSC LDC-23.10.2016]
(1) Monohybrid cross
(2) Dihybrid cross
(3) Test cross
(4) Back cross
Mendel's Law of Independent Assortment is based on observations from Dihybrid Cross experiments.
With the help of which dye can DNA fragments be visualized after separation on agarose gel?
DNA fragments can be visualized under UV light using Ethidium bromide dye as it binds to DNA and fluoresces.
Chimeric DNA is called - [RPSC LDC - 17.02.2012]
Recombinant DNA is called Chimeric DNA because in this, DNA from two different sources or species is combined to create new DNA.
What is meant by Biomagnification?
In a food chain, organisms consume each other. In this process, some harmful chemical substances are transferred from one organism to another through the food chain. This is called biomagnification.
The basis of DNA fingerprinting is-
DNA polymorphism means variation in DNA sequence. Since each individual's DNA sequence is unique, it forms the basis of DNA fingerprinting.

What is meant by Bioremediation?
Bioremediation (i.e., treatment by living organisms) is a process in which microorganisms like bacteria or their enzymes are used to try to restore a polluted environment to its original state.
Which of the following is most essential for seed germination?
Water, proper temperature, and oxygen (air) are essential factors for seed germination. Among these, water is the most critical as it activates enzymes within the seed and helps the embryo to swell and rupture the seed coat.
Who gave the 'Theory of Natural Selection'?
The theory of Natural Selection was given by Charles Darwin.
What is a GMO?
A Genetically Modified Organism (GMO) is an organism whose genes have been altered with the help of biotechnology.
Recently in which city of India was Asia's first DNA bank established? [RAS-2009]
The world's first DNA bank is located in America, and Asia's first (second in Asia if viewed globally) DNA bank was established in Lucknow.
Chromosomes are made of- [Tax Assistant-14.10.2018]
(1) DNA
(2) RNA
(3) DNA and RNA
(4) DNA, RNA and Histone
Chromosomes are mainly composed of DNA, RNA, and histone proteins.
Genetic engineering is related to-
The technique in which DNA of one species is introduced into the DNA of another species to obtain recombinant DNA is called genetic engineering or recombinant DNA technology. The term genetic engineering was first used by A.C. Palrb.
Identify the uses of genetically modified (GM) plants from the following:
The benefits of genetically modified (GM) plants include: reducing post-harvest losses, increasing nutritional value (e.g., Golden Rice), and reducing dependency on chemical pesticides (e.g., Bt cotton). Option 4 is incorrect because the goal of GMOs is to increase, not decrease, mineral use efficiency.
Who proposed the Central Dogma of protein synthesis?
The mutual relationship between nucleic acids and proteins is known as the Central Dogma. It was proposed by Crick (1958).
Which of the following transgenic animals are produced in the maximum number?
Mice are used the most in genetic research because their genome is quite similar to humans and they are easy to raise in a laboratory.
