Explanation / Answer

47. Answer. Euchromatin is lightly and heterochromatin is darkly stained regions of DNA in chromosome. Heterochromatin contains non-translating short DNA sequences with multiple repeats known as STRs.

49. Answer:

2.      Metaphase in mitosis and meiosis-II will be similar but difference will be there in no. of chromosomes.

3.      In meiosis-I metaphase sister chromatids will remain attached at centromere and homologous chromosomes will be allowed to separate by moving towards poles. Whereas in mitosis and meiosis-II, sister chromatids will be detaching from centromere and moving towards poles.
