MAKE CONNECTIONS Although the proteins that cause the E. coli chromosome to coil are not histones, what property would you expect them to share with histones, given their ability to bind to DNA (see Figure 5.14)?

Hello everyone. And in today's video we have the following problem in the nuclear some complex what what makes the D. N. A. And his sense strongly adhere to each other. So let's keep in mind these terms strongly a deer. It means that they're attracted to each other and it is going to be very important in order to solve the problem. So before we jump into the answer choices, let us quickly be reminded of what the nuclear some complex is and there's nothing more than D. N. A. Wrapped around a core of proteins in the nucleus. And so this is going to be very important because it is mostly composed of DNA and histone proteins. And so very important characteristic of D. N. A. Is that it's made up of these phosphate groups that make up its skeleton or just help support it. These phosphate groups as we can see are very much negatively charged. On the other hand, we have his stints also being part of that nuclear some complex and these histamines are proteins and they are made up since their proteins are made up of amino assets and there is many amino assets such as arginine and licensing that make up these histamines and so they're very much positively charged. And since the histamines are positively charged or overall positively charged and the D. N. A. R. Are negatively charged, they're going to attract each other, they're going to strongly adhere to each other. Getting this nucleus and complex. And so we're going to highlight answer choice B because of their opposite charges as it is going to be the reason why these two molecules are able to stick to each other so strongly, so it's going to be the end of the video. I really hope this video helped you.
