DNA Supercoiling observation that polyoma virus DNA preparations had 3 different types of DNA which had uniquely different sedimentation velocities , two are circular, one linear One circular molecule is underwound Negatively supercoiled more than Polytene Chromosomes Balbiani, Certain dipteran cells e. Lampbrush Chromosomes Vertebrate oocytes, some insect spermatocytes Diplotene of meiosis. Look like a brush used to clean kerosene lamp chimneys Useful for studies of crossing over and gene expression. DNA Condensation DNA duplex 2 nm in diameter Nucleosome string about 11 nm in diameter Nucleosomes form coiled solenoid-shaped fiber with 6 nucleosomes per spiral 30 nm fiber.

The sequence of bases within a DNA molecule represents the genetic information of the cell. Segments of DNA molecules are called genes , and individual genes contain the instructional code necessary for synthesizing various proteins, enzymes, or stable RNA molecules. The full collection of genes that a cell contains within its genome is called its genotype. However, a cell does not express all of its genes simultaneously. Instead, it turns on expresses or turns off certain genes when necessary. Genes that are always expressed are known as constitutive genes ; some constitutive genes are known as housekeeping genes because they are necessary for the basic functions of the cell.

The genome organisation: repetitive and unique sequences Recapping…. The plant nuclear genome consists of DNA divided among the chromosomes within the cell nucleus. Genome organization 1. Chloroplasts play a crucial role in sustaining life on earth.

Both types of cells are enclosed by cell membranes plasma membranes , and both use DNA for their genetic information. Prokaryotes include several kinds of microorganisms, such as bacteria and cyanobacteria.

Тогда они оба подумали, что он где-то допустил ошибку, но сейчас-то она знала, что действовала правильно. Тем не менее информация на экране казалась невероятной: NDAKOTA ETDOSHISHA. EDU - ЕТ? - спросила Сьюзан.

Она была убеждена, что именно это качество определило всю его карьеру и вознесло на высшие этажи власти. Уже направляясь к двери, Сьюзан внимательно посмотрела на ТРАНСТЕКСТ. Она все еще не могла свыкнуться с мыслью о шифре, не поддающемся взлому. И взмолилась о том, чтобы они сумели вовремя найти Северную Дакоту.
