A rapidly growing bacterial species such as E. coli exhibits a typical phase of growth cycle in liquid nutrient broth (lag phase → log phase → stationary phase → death phase). If a bacterial culture has starting density of 10³ cells/ml has a lag time of 10 minutes and a generation time of 10 minutes, what will the cell density be at (cells/ml) 50 minutes?

Find correct True and False statements

A. Human females have 23 different chromosomes, whereas human males have 24.

B. In the living cell, chromatin usually adopts the extended “beads-on-astring” form.

C. The four core histones are relatively small proteins with a very high proportion of positively charged amino acids; the positive charge helps the histones bind tightly to DNA, regardless of its nucleotide sequence.

D. Nucleosomes bind DNA so tightly that they cannot move from the positions where they are first assembled.
