Re: AIPMT Old Question

As you Asking for the Question Paper of the AIPMT Examination let me tell you that the AIPMT Examination is Replaced by the NEET Examination Here I am giving you the Question Paper of the NEET Examination Biological Section

Which one of the following does not differ in E.coli and Chlamydomonas?
Cell wall
Cell membrane
Ribosomes
Chromosomal organization


Question 2
Select the correct statement from the following regarding cell membrane

Lipids are arranged in a bilayer with polar heads towards the inner part.
Fluid mosaic model of cell membrane was proposed by Singer and Nicolson.
Na+ and K+ ions move across cell membrane by passive transport.
Proteins make up 60 to 70% of the cell membrane


Question 3

What is true about ribosomes?

These are found only in eukaryotic cells
These are self-splicing introns of some RNAs.
The prokaryotic ribosomes are 80S, where "S" stands for sedimentation coefficient
These are composed of ribonucleic acid and proteins.
Question 4
Ribosomal RNA is actively synthesized in :

Nucleoplasm
Ribosomes
Lysosomes
Nucleolus


Question 5
E. Coli about to replicate was placed in a medium containing radio active thymidine for five minutes. Then it was made to replicate in a normal medium. Which of the following observation shall be correct?


Both the strands of DNA will be radio active
One strand radio active
Each strand half radio active
None is radio active


Question 6

Assertion: A cell membrane shows fluid behaviour.
Reason: A membrane is a mosaic or composite of diverse lipids and proteins.
Both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
Both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion.
Assertion is true statement but Reason is false.
Both Assertion and Reason are false statements.

Question 7
A nucleosome is a portion of the chromonema containing ______.
both DNA and histones
only histones
both DNA and RNA
only DNA


Question 8
If a cell has twice as much DNA as in a normal functional cell, it means that the cell ______.

has completed division
is preparing to divide
has ceased to function
has reached the end of its lifespan

Question 9
What is the common point of similarity between DNA and RNA?

Both are double stranded
Both have identical sugar molecules
Both have identical pyrimidine bases
Both are polymers of nucleotides


Question 10
Cell wall consists of
Lignin, hemi cellulose, pectin and lipid
Lignin, hemi cellulose, pectin and cellulose
Lignin hemi cellulose, protein and lipid
Hemi cellulose, cellulose, tubulin and lignin


Question 11

Cytoskeleton is made up of
Proteinaceous filaments
Calcium carbonate granules
Callose deposits
Cellulosic microfibrils

Question 12
Vacuole in a plant cell :

Lacks membrane and contains water and excretory substances
Is membrane-bound and contains storage proteins and lipids
Is membrane-bound and contains water and excretory substances
Lacks membrane and contains air

Question 13
Polysome is formed by

Ribosomes attached to each other in a linear arrangement
Several ribosomes attached to a single mRNA
Many ribosomes attached to a strand of endoplasmic reticulum
A ribosome with several subunits

Question 14
The rough endoplasmic reticulum (RER) in the cells are because of the presence of

Mitochondria associated with ER
Ribosomes on the surface of ER
Volutin granules on the surface of ER
Sulphur granules on the surface of ER

Question 15

Assertion: Eukaryotic cells have the ability to adopt a variety of shapes and carry out directed movements.

Reason: There are three principal types of protein filaments-actin filament, microtubules and intermediate filaments, which constitute the cytoskeleton.

Both assertion and reason are true and the reason is the correct explanation of the assertion

Both assertion and reason are true but the reason is not the correct explanation of the assertion.

Assertion is true statement but reason is false.
Both assertion and reason are false.
