Question 1. Single Answer 1.00 marks, , DNA does not occur in, , (J A. Nucleus, B. Ribosomes, (J C. Mitochondria, , (] D. Plastids, , Y Correct, , Solution, , , , DNA is a genetic material which is mainly, present in the nucleus of the cell in eukaryotes., In prokaryotes, they lie freely in the cytoplasm., The functional segments of the DNA are, , known as genes. Mitochondria and chloroplast, are the only organelles which are semiautonomous which have their own DNA., Mitochondrial DNA is known as mt-DNA and, the chloroplast is known as ct-DNA.So, the, correct answer is option B.

Question 2 Single Answer 1.00 marks, , An anaphase chromosome contains, , CL) A.1DNA molecule, () B.3DNA molecule, C. 2 DNA molecule, , () D.4 DNA molecule, , X Student's answer was incorrect, , , , Solution, , During mitosis, anaphase stage is, characterized by splitting of the centromere., The DNA molecule in each chromosome, replicates in the synthesis or S phase, , of interphase and thus, it possess two DNA, molecules. At anaphase stage, each, chromosome splits at the centromere and, each daughter chromosome thus produced is, left with a single molecule of DNA only.So, the, correct answer is option A.

Question 4 Single Answer 1.00 marks, , Which of the following statements about cell, structure is NOT correct?, , , , A. plant cell have chloroplast, where as, animals cell do not., , , , , , , , , , B. Plant cell have cell wall, where as animal, Cells do not., , , , C. Ribosomes are main site for energy, production of the cells, , 0 D. many cellular organelles are interrelated, through an endomembrane system, , Y Correct, , , , , , , Solution, , e Mitochondria are called the powerhouse, of the cell, as these organelles are where, most of the cell's energy is produced., Ribosomes are the sites in a cell in which, protein synthesis takes place., , So, the correct answer is ‘ribosomes are the, main site for energy production of the cells

Question 5 — Single Answer 1.00 marks, , All are membrane bounded cell organellesexcept, , [_] A. Mitochondria, [_] B. Spherosomes, C. Ribosomes, , [-] D. Lysosomes, , Y Correct, , , , , , , , , , Solution, , , , In the eukaryotic cell, all the organelles are, membrane-bounded but prokaryotic cell, possesses organelles that not bound by the, membranes. The ribosome is the only, organelle found in both prokaryotic and, eukaryotic cells. Thus ribosome is not, bounded by the membrane.
