WebThese DNA-associated proteins organize the DNA and help it fit into the nucleus, and they also play a role in determining which genes are active or inactive. The complex formed by DNA and its supporting structural proteins is known as chromatin. You can learn more about DNA, chromatin, and chromosomes in the DNA and chromosomes article. WebNow let’s consider the structure of the two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base ( Figure 9.3 ). There are four types of nitrogenous bases in DNA.

WebSep 30, 2009 · An analogy of a nucleus is that it is like a brain. It controls the rest of the body and what goes on mostly. Without it, you body would get confused and then you would … Stress that when the thread ( DNA) is being used ( during interphase) it is not so tightly coiled or wound and this is analogous to DNA in a working cell. Next, take a colored marker and color over a two foot section of the thread. Equate this to the DNA nucleotide sequence for a particular gene.

The total DNA in the cell is about 5 to 6 feet long which has to fit inside the nucleus of a cell in an orderly fashion. DNA molecules first wrap around the histone proteins forming beads on string structure called nucleosomes. Nucleosomes further [inaudible] and condense/gather to form fibrous material which is called chromatin. how do you clean perky pet hummingbird feeder
