Hi, I'm Michael Maidaa, and this is "the genetic structure located within the nucleus of each cell." This genetic structure is called a chromosome. Chromosomes are basically long stretches of DNA that are compacted very tightly and stuffed into the nucleus. So, here, we have a strand of DNA. The DNA consists of several different genes. Genes are segments of the DNA. So, a chromosome is basically a bunch of different genes packed together to form the shape of a chromosome. The chromosome then has all of the DNA necessary for a cell, and humans have 23 of these chromosomes. And, the majority of them are located in the cell, but specifically in the nucleus of the cell. So, in the nucleus of each cell, we have these 23 pairs of chromosomes all tightly packed together and stuffed into the nucleus. I'm Michael Maidaa and this has been "what genetic structures are located within the nucleus of each cell?"
