GATE Biotechnology Mock Test - 7 - Question 3

Let m and n be positive integers such that m is less than n. What will be the value of ?

Detailed Solution for GATE Biotechnology Mock Test - 7 - Question 3

Since the result must work no matter what positive integers m and n we choose with m < n, We can try m = 1 and n = 2.

GATE Biotechnology Mock Test - 7 - Question 4

In my basket of fruits, there are apples and oranges. The ratio of apples to oranges is 3 : 8. After I take out one apple, the ratio changes to 1 : 3. How many oranges are present in the basket?

Detailed Solution for GATE Biotechnology Mock Test - 7 - Question 4

Suppose there are initially m apples and n oranges in the basket.
Since m : n = 3 : 8, it follows that 8m = 3n. After removing one apple, the ratio becomes (m – 1) : n = 1 : 3.
So, 3(m – 1) = n.
Putting these two equation together,
8 m = 3 × 3(m – 1)
8 m = 9 m – 9
m = 9

Hence, there are 24 oranges in the basket.

GATE Biotechnology Mock Test - 7 - Question 5

How many solutions exist for the following set of linear equations?
–x 5y = –1
x – y = 2
x 3y = 3

Detailed Solution for GATE Biotechnology Mock Test - 7 - Question 5

–x + 5y = –1
x – y = 2
x + 3y = 3
The average mented matrix is 
Using gauss-elimination on above matrix we get,
Rank [A|B] = 2 (number of non zero rows in [A|B])
Rank [A] = 2 (number of non zero rows in [A])
Rank [A|B] = Rank [A] = 2 = number of variables
Hence, unique solution exists. Correct choice is (c).

GATE Biotechnology Mock Test - 7 - Question 6

Examine the subsequent set of equations involving three real variables x1, x2, and x3.
2x1 – x2 3x3 = 1
3x1 – 2x2 5x3 = 2
–x1 – 4x2 x3 = 3
This set of equations possesses

Detailed Solution for GATE Biotechnology Mock Test - 7 - Question 6

The augmented matrix for the given system is 
Using gauss-elimination method on above matrix we get,

Rank ([A|B]) = 3
Rank ([A]) = 3
Since, Rank ([A|B]) = Rank ([A]) = number of variables. The system has unique solution.

GATE Biotechnology Mock Test - 7 - Question 12

Identify the statement that is incorrect regarding protein kinase C (PKC).

GATE Biotechnology Mock Test - 7 - Question 13

Which characteristics of human DNA are utilized in the process of DNA fingerprinting?

Detailed Solution for GATE Biotechnology Mock Test - 7 - Question 13

Within a species, the nucleotide sequences of the repeat units composing VNTR are highly conserved among individuals. However, differences in the number of repeats, and thus in the length of simple-sequence tandem arrays containing the same repeat unit, are quite common. This feature of VNTR's is exploited by DNA fingerprinting.

GATE Biotechnology Mock Test - 7 - Question 14

Which of the following represents a model for predicting the secondary structure of proteins?

Detailed Solution for GATE Biotechnology Mock Test - 7 - Question 14

(Given that sin 30 = 0.5 and sin 60 = 0.866). Utilize Abbe's formula and Rayleigh correction to determine the resolution.

GATE Biotechnology Mock Test - 7 - Question 22

What is the enthalpy of 130 g of formic acid at a temperature of 70°C and a pressure of 1 atm, compared to its enthalpy at 25°C and 1 atm? The specific heat capacity (Cp) for formic acid within the relevant temperature range is 0.524 cal g–1 °C–1.

Detailed Solution for GATE Biotechnology Mock Test - 7 - Question 22

ΔH = (130 g) (0.524 cal g–1 °C-1) (70-25)°C
ΔH = 3065.4 cal
