Answer 1

1) cell bursting is referred to as cell lysing so the answer is a) lysing

2) DNA is the genetic molecule that passes hereditary information along generations so the answer is b. hereditary

3) DNA is condensed during mitosis, DNA which remains as chromatin condenses to chromosome in Prophase of mitosis so the answer is c. mitosis

4) In humans there are 23 pairs or 46 chromosomes so the answer is c) 46

5) DNA is wrapped around histone proteins which helps to pack long DNA molecules within nucleus so the answer is e) histones

6) to collect the DNA from the cell, the cell membrane must be disrupted using detergent so the answer is a) phospholipid bilayers
