Human insulin molecule is composed ofone α-chain having 21 amino acids andone β-chain having 30 amino acids. How many functional insulin genes occur in adult humans? Correct Answer One

In some animals there are two insulin genes; however, in most others, including humans, a single gene is present. The insulin gene present on chromosome 11 in humans. The insulin is synthesized as 'proinsulin', which is modified to make two functional polypeptides.

A insulin producing company starts the production with 4 kg of insulin, the next day the amount of insulin was increased to 12 kg. If the amount of insulin on the n + 1th day : amount of insulin on nth day ∷ amount of insulin on nth day : amount of insulin on the n – 1th day and once the amount of insulin crosses 100 kg, 90 kgs of the insulin is removed. What will be the total production of insulin in 23 days?
"Too often we try to solve human problem with non-human tools and in terms of non-human data. It is my simple thesis that a human problem requires a human solution. First we have to learn to recognise a human problem when we see one; and second, upon recognising it, we have to learn to deal with it as such and not as it were something else. A human problem to be brought to a human solution requires human data and human tools". Who said this?

Consider the following statements regarding genetic code and choose the correct answer:
1. The genetic code is degenerate
2. In all amino acids the first two bases are the same in all the codons that represent a particular amino acid
3. The number of codons an amino acid can claim is proportional to the frequency of the amino acid in proteins
4. Amino acids with codons ending in U or A also have codons ending in C or G respectively
Consider the following four relational schemas. For each schema, all non-trivial functional dependencies are listed. The underlined attributes are the respective primary keys. Schema I: Field ‘courses’ is a set-valued attribute containing the set of courses a student has registered for. Non-trivial functional dependency: rollno → courses Schema II: Non-trivial functional dependencies: rollno, courseid → email email → rollno Schema III: Non-trivial functional dependencies: rollno, courseid → marks, grade marks → grade Schema IV: Non-trivial functional dependencies: rollno, courseid → credit courseid → credit Which one of the relational schemas above is in 3NF but not in BCNF?
Humans and robots can both perform a job but at different efficiencies. Fifteen humans and five robots working together take thirty days to finish the job, whereas five humans and fifteen robots working together take sixty days to finish it.

The following sentences form a paragraph. These four parts are numbered as P, Q, R and S. They are not given in their proper order. Read the sentences and choose the alternative that arranges them in correct order. P. The hypothesis was proposed as an explanation for the increased prevalence of type-2 diabetes in certain populations by American geneticist James V. Neel. Q. Thrifty genes refers to a scientific hypothesis which states that obesity in some human beings can be explained by the existence of a ‘thrifty gene’ that aided the storage of excess energy as fat. R. The same genes, however, turned into a biological liability that led to obesity in some people. S. According to the hypothesis, certain genes, by helping in the storage of energy as fat, might have enabled human ancestors live through periods of famine, thus enhancing their chances of survival.
