A Basic Guide to Answers to the Question, Which of the Following Statements About the DNA in One of Your Brain Cells is True?
DNA is responsible for creating all of the cells in your body. It is a genetic material that codes for the characteristics of each cell that makes up your body. For example, every red blood cell is created from DNA that has the same code as all other red blood cells. This is the basis of what scientists refer to as “population” genetics. Every aspect of life including human reproduction has a component of population genetics.
So we know that the DNA that is responsible for creating all life on earth is passed down from generation to generation. And we also know that every generation has a different set of DNA, which means that we are all different. Now, back to the original question, which of the following statements about the dna in one of your brain cells is true? Well, the answer is: all of them. As long as you have the necessary DNA for creation, every one cell in your body will create the same exact result.
However, there are things that can change this. For example, if you are African American and you have inherited a large portion of Europeans DNA from a spouse who was Hispanic, then your DNA will be very different than if you were to have an identical twin. Another example is if you are Asian and your parents were both men. Your Y chromosome will contain a lot more Asian DNA than your autosomes. And just think about having children of both parents…your child will be more likely to have Asian DNA than his/her parents. So it’s important that you realize the potential for differences when it comes to which of the following statements about the dna in one of your brain cells is true?
So what are the answers to these questions? The truth is that the answer depends upon how much DNA you actually have from each parent. If you have more DNA from one of the parents than the other, then the DNA is more likely to be from that parent than the other one. The reason for this is that more DNA means a more complex set of cells, and therefore more likelihood of having errors. However, if you have less DNA from one of the parents than the other, then the chances of the error being present in the cells are lessened.
Hopefully, now you understand why there are two statements about the DNA in one of your brain cells being true. And hopefully you also understand why it is possible for both of these statements to be false. But the important thing here is not to stop worrying because, even though the DNA may prove one or the other of these statements to be false, it does not mean that either one of those statements is necessarily true. What it means is that we need to continue to study DNA and find out all we can about this subject! After all, without a solid foundation for DNA studies, the field will truly be a blank slate.
