Question

14) Which of these is a CORRECT statement about monoderms and/or diderms?

a) All prokaryotes are monoderms.

b) All prokaryotes are diderms.

c) Prokaryotes can be monoderms or diderms.

d) Diderms correspond to the Gram-positive bacteria.

e) Diderms correspond to the Gram-negative bacteria.

15) Which of these is NOT a type of light microscopy?

a) Bright field

b) Phase contrast

c) DIC

d) Electron microscopy

e) Nomarski optics

16) Which of these is NOT required to form a nucleosome?

a) At least ~147 bp of DNA

b) Core Histone H3

c) Core Histone H4

d) Core histones H2A and H2B

e) Linker histone H1

7) Estimate the typical number of nuclear pores in a mammalian nucleus. Show your reasoning/math.

14. C they can be both monoderms and diderms

E is also correct

Monoderms mean gram positive

Diderms mean gram negative

15. D electron microscope

In all of them light is used and in electron microscopy electron beam is used.

16. Linker histone H1 is not a part of nucleosome.

So all of them are a part of nucleosome.

A nucleosome contains DNA wrapped around a protein core H2a,H2b, H3,H4
