the challenge of folding the 6 billion base pairs in the chromatin into the tiny nucleus. It doesn't just have to fit, you have to be able to find what you need! Question: Some of the structure is conserved across species and some structure changes cell to cell. Can you explain that?
Which of the following statements concerning eukaryotic chromatin is true. Histones have an overall negative charge. Euchromatin is more condensed then heterochromatin. After replication nucleosomes are made up of a mixture of old and new histone proteins. Euchromatin is associated with the centromere and telomere regions. Heterochromatin are regions of active transcription.
What is the structure of telomeres? short, repetitive DNA sequences found at the ends of linear eukaryotic chromosomes long, repetitive DNA sequences found at the ends of linear eukaryotic chromosomes short, repetitive DNA sequences found at the ends of linear prokaryotic chromosomes long, unique DNA sequences found at the ends of linear eukaryotic chromosomes
For the question "4. 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 7x 106 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?" I was given the answer below: As per question the chromosome contains 7×106 base pairs of DNA, The number of nucleosomes, each containing 7 × 102 base pairs, is equal to : 7 × 106 /7 × 102 = 104 nucleosomes I was wondering how they knew each nucleosome contains 7 × 102 base pairs?

Malaria, one of the most pervasive and destructive of all infectious diseases, is caused by protozoan parasites of the genus Plasmodium, which are transmitted from person to person by mosquitoes. Plasmodium parasites are able to evade the host immune system by constantly altering the expression of their var genes, which encode Plasmodium surface antigens (L. H. Freitas-Junior et al. 2005. Cell 121:25–36). Individual var genes are expressed when chromatin structure is disrupted by chemical changes in histone proteins. What type of chemical changes in the histone proteins might be responsible for these changes in gene expression?
