Wouldn't be surprised if it reached $80-100 even for a one bedroom those months. Can't tell you much about the others, except that water and sewer are generally small everywhere (hot water costs, but with gas). You should be aware that in some big buildings, your cost doesn't depend on your usage.
Okazaki fragment. Definition. noun, plural: Okazaki fragments. Relatively short fragment of DNA synthesized on the lagging strand during DNA replication. Supplement. At the start of DNA replication, DNA unwinds and the two strands splits in two, forming two prongs which resemble a fork (thus, called replication fork).
You now know that Okazaki fragments are the fragments of DNA that are created when the complementary strand to the lagging strand is created. They occur because of the fact that the lagging strand is exposed in the 3' - 5' direction, while DNA synthesis has to occur in the 5' - 3' direction. You know that the fragments were named after Reiji Okazaki, the scientist who discovered the fragments.
