In salivary gland chromosomes/polytene chromosomes, pairing is:
1 Absent
2 Occasional
3 Formed between non-homologous chromosomes
4 Formed between homologous chromosomes.
Explanation:
Exp:D In salivery gland chromosomes/polytene chromosomes, pairing is formed between homologous chromosomes. A characteristics feature of these chromosomes is that somatic pairing occurs in them and hence their number appears half of normal somatic cells. Polytene chromosomes develop from the hromosomes of diploid nucleic by successive duplication of each chromosomal element without their segregation.

A conspicuous rounded body present in nucleoplasm and attached to a particular chromosome at a definite place is
1 plasmid
2 karyolymph
3 nucleolus
4 nuclear reticulum
Explanation:
Exp:C Nucleoplasm is a spherical body attached with nucleolar organizing chromosome on definite position is called nucleolus. It is largest nuclear organelle \& primary site of ribosome subunit biogenesis in eukaryotic cells.

Structure present over the chromosomes is
1 nucleolus
2 centromere
3 centrosome
4 Golgi complex
Explanation:
Exp:B Centromere is also called kinetochore. It is the primary constriction at which spindle attaches during cell division. It is the last part to get duplicated in dividing chromosomes. Centromere contains highly repeated satellite DNA. Position of centromere describes shape of chromosomes.

Which of the following is stained using carmine?
1 Bacteria
2 Diatoms
3 Chromosomes
4 Viruses
Explanation:
Exp:C Carmine is the basic dye used to stain nucleic acid and chromosomes given pink colour. Acetocarmine is saturated solution of carmine in \(45 \%\) acetic acid used for sapid staining of fresh unfixed chromosomes. It is used to study stages of cell division. Carmine is prepared by coccus cacti(insect)
