Both the wine marker and a molecular biologist who has developed a recombinant vaccine claim to be biotechnologist. Who in your opinion is correct?

Biologist who has been called the "Dawrin of the 20 century" was:

Two questions consist of two statements each, printed as Assertion and Reason. While answering these questions, you required to choose any one of the following four responses. If both Assertion and Reason are true and Reason is a correct explanation of Association. If both Association and Reason are true and Reasons is not a correct explanation of Assertion. If Assertion is true but Reason is false. If both Assertions and Reason are false. Assertion: DNA segments can be excised by 'molecular scissors or chemical scalpels' what biotechnologists call restriction enzymes. Reason: Restriction enzymes are synthesized by microbes as a defence mechanism are specific endonucleases which are cleave double stranded DNA.

In a class of 25 students, 12 have taken Mathematics. 8 have taken Mathematics but not Biology. Find the number of students who have taken both Mathematics and Biology and the number of those who have taken Biology but not Mathematics. Each student has taken either Mathematics or Biology or both.

These questions consist of two statement each, printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses. A. If both Assertion and Reason are true and Reason is a correct explanation of the Assertion. B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion. C. If Assertion is true but Reason is false. D. If both Assertion and Reason are false. Assertion: A person who has received a cut and is bleeding needs to be given anti-tetanus treatment. Reason. Anti-tetanus injection provides immunity by producing antibodies for tetanus.

A factory owner purchases two types of machines, A and B fo his factory. The requirements and the limitation for the machines are as followes : He has maximum area of 9000 m^2 available, and 72 skilled labourers who can operate both the machines. How many machines of each type should be buy to maximise the daily output ?

The questions given below consist of an Assertion and Reason. Use the following key to choose of the appropriate answer. If both assertion and reason are CORRECT and reason if the CORRECT explanations of the assertion. If both assertion and reason are CORRECT but, reason is NOT THE CORRECT explanation of the assertion. If assertion is CORRECT explanation of the assertion. If both assertion and reason are INCORRECT. Assertion: Camphor is usually used in molecular mass determination Reason: Camphor has low cryscopic constant and therefore, causes greater depression is freezing point.
