The nucleosome core particle: a) contains about 145 based of DNA b) contains 6 histone proteins  c) contains histone H1 d) none of the above

A previously undiscovered single celled organism was found living at a great depth on the ocean floor. Its nucleus contains only a single, linear chromosome consisting of  7x10^6 nucleotide pairs of DNA coalesced with three types of histone-like proteins. The analysis of individual nucleosomes revealed that each unit contained one copy of each protein and that the short linker DNA had no protein bound to it If the entire chromosome consists of nucleosomes (discounting any linker DNA), how many are there and how many total proteins are needed to form them?

In prophase genetic material condenses and coils into what form of genetic material?

Consider two different proteins that are leaving from the Golgi in order to arrive in their common destination, a lysosome. In order for these two different proteins to be sent to the same place, what should they have in common? A) They must have the same primary structure B) They must have been imported into the cell by endocytosis. C) They must have the same tertiary structure D) They probably have the same glycosylation pattern. ..
