Re: Taxi transfer from Havana airport to Varadero. Jan 19, 2006, 8:39 AM. There will be no problems in getting a taxi at Jose Marti airport in Havana. A ride to Varadero will cost you in the area of 80 to 100 CUC (Cuban Convertible Peso). You should exchange some money to CUC while you wait for your baggage. There are two CADECA money booths on the arrivals level.
Chromosomal DNA and Its Packaging in the Chromatin Fiber. The most important function of DNA is to carry genes, the information that specifies all the proteins that make up an organismâincluding information about when, in what types of cells, and in what quantity each protein is to be made.lthough long strings of nucleosomes form on most chromosomal DNA, chromatin in a living cell probably rarely adopts the extended âbeads on a stringâ form. Instead, the nucleosomes are packed on top of one another, generating regular arrays in which the DNA is even more highly condensed.
Best Answer: A chromosome is an organized structure of DNA and protein (Chromatin) that is found in cells. Chromosomes contain DNA-bound proteins, which serve to package the DNA and control its functions. The essential unit of DNA packaging is the nucleosome. A nucleosome consists of a small amount of DNA wrapped up with protein. The proteins that interact with DNA to form chromatin comprise a family of basic proteins called histones. There are five different types of histone protein: H1, H2A, H2B, H3, and H4. Of these, two molecules each of H2A, H2B, H3, and H4 combine to form a histone octamer. DNA wraps around the octamer, making 1 3/4 turns around the protein complex. The octamer plus the DNA comprise what is called the nucleosome core. A small stretch of DNA runs between adjacent nucleosome cores, and is known as the linker. A single nucleosome consists of one core plus a linker.
