WebThe short answer is that chromosomes found in the nucleus of plant cells are composed of chromatin (optional reading). Chromatin is made up of DNA wrapped around proteins, … WebChromosomes are made of a single molecule of DNA wrapped around a small, spool-like protein called a histone. The wrapping of DNA around a histone is important, as otherwise most DNA molecules would not fit inside of cells.

WebHelicase separates the two template strands of DNA. 2. Binding of proteins to the two template strands prevents them from rejoining. 3. Primase adds short stretches of RNA to the template DNA strand. 4. DNA polymerase adds DNA nucleotides to create the newly synthesized strand. 5. WebDuring the 1980s and 1990s, researchers discovered that multiple proteins act together to fold and condense prokaryotic DNA. In particular, one protein called HU, which is the …
WebThey are the basic unit of DNA packingThe string between the beeds in known as linker DNA. COnsists of DNA wound twice around a protein core consisting of 2 molecules of each type of the 4 main types. The amino end (N terminus) of each histone extends outward from the nucleosome. When do histones go away.
WebThe protein that is coiled around the DNA in chromatin is called histone. When the chromatin condenses, it is referred to as chromosomes. The proteins help package the DNA into the...
