Hello,

I would like to tell you that the chapter biomolecules as a whole has a weightage of 3% which is around 1-2 questions.

There isn't any particular structure repeating but you can always look for previous papers for more info.

For more info on weightage, I would suggest you to visit the career360's link given below which contains the list of weightages of all chapters which will help you to study efficiently.

The link for the same is:https://medicine.careers360.com/articles/neet-chapter-wise-weightage-and-important-topics

Hope this helps and all the very best Kiran!
