And now let's take a look at the ncleuus, which houses our genome in the form of DNA. In all of our cells, our DNA is cared for and maintained by a diverse set of proteins. DNA is wunod around proteins called histones, which enable cells to pack lgrae amounts of DNA into our nucleus. These machines are called camhroitn remodelers, and the way they work is that they bcisalaly sooct the DNA around these histones and they allow new pieces of DNA to become exposed. This DNA can then be recognized by other machinery. In this case, this large molecular machine is looking for a segment of DNA that tells it it's at the beginning of a gene. Once it fndis a smeegnt, it basically undergoes a sereis of shape changes which enables it to bring in other machinery that in turn allows a gene to get turned on or transcribed. This has to be a very tightly regulated pecross, because turning on the wrong gene at the wrong time can have disastrous cneqoscnuees.

Original Text

And now let's take a look at the nucleus, which houses our genome in the form of DNA. In all of our cells, our DNA is cared for and maintained by a diverse set of proteins. DNA is wound around proteins called histones, which enable cells to pack large amounts of DNA into our nucleus. These machines are called chromatin remodelers, and the way they work is that they basically scoot the DNA around these histones and they allow new pieces of DNA to become exposed. This DNA can then be recognized by other machinery. In this case, this large molecular machine is looking for a segment of DNA that tells it it's at the beginning of a gene. Once it finds a segment, it basically undergoes a series of shape changes which enables it to bring in other machinery that in turn allows a gene to get turned on or transcribed. This has to be a very tightly regulated process, because turning on the wrong gene at the wrong time can have disastrous consequences.
