Doubtful Questions

There are three questions about which doubts are being raised and students are saying that NTA official keys are wrong. There are 3 such questions in Biology.

Question No 1: Cells in G-O phase

  1. Enter the cell cycle
  2. Suspend the cell cycle
  3. Terminate the cell cycle
  4. Exit the cell cyle

The correct answer for this question is option b) not d) as claimed by a lot of coaching institutes. This question was also asked in WBJEE few years back. Answer key provided by NTA is perfectly okay here.

Question No 2: Which of the following statements is correct

  1. Cornea consists of dense connective tissue of elastin and can repair itself.
  2. Cornea is convex, transparent layer which is highly vascularized.
  3. Cornea consists of dense matrix of collagen and is the most sensitive portion of the
  4. Cornea is an external, transparent and protective proteinaceous covering of the eye-ball.

The correct answer for this question is c) as well as d). Official answer-key released by NTA is c) and so, students can challenge the official key released for this question.

Question No 3: Consider the following statements:

  1. Coenzyme or metal ion that is tightly bound to enzyme protein is called prosthetic group.
  2. A complete catalytic active enzyme with its bound prosthetic group is called apoenzyme.

Select the correct option.

  • A is true but B is false
  • Both A and B are false
  • A is false but B is true.
  • Both A and B are true.

NTA official key  for this question is 1) as opposed to answer provided by coaching institutes which is 2). In this case too, answer provided by NTA seems correct and challenging it would not yield much benefit.

Apart from this, there are few other questions too about which objections are being raised. But, they seem okay on closer scrutiny and so, there won’t be much benefit in challenging those questions.
