Document Summary
Host cell a cell that is infected by viruses. Host range the amount of types of cells that a virus can infect. Bacterial genome content: singular circular chromosome, structural genes densely packed regions of the chromosome that contains the. Dna sequences that encode bacterial proteins: repeatitive sequences small amounts of repetitive dna sequences that are found in multiple copies in the chromosome; are rarely transcribed but are important for replication. Chromatin a mixture of the dna that makes up the chromosomes along with an array of proteins that organize and compact the dna. Dnases digest fragments of 150-200bp which is in accordance with core. Dna and the such: 30nm fiber the most common form of chromatin condensation, solenoid structure. Nucleosome distribution and synthesis during replication: current model for nucleosome distribution and synthesis as replication fork passes, nucleosomes break down into protein subunits, but almost instantly rejoin on one of the daughter strands. 11. 4 chromatin compaction varies along the chromosome.
