    00:01 Here's another straightforward one, "Which of the following cells in the blood do not have a nucleus?" Well, let's see. We got A, B, C, D, down on your paper.

    00:12 Okay. Now let's look at white blood cells.

    00:15 I always like to start at the top and work my way down.

    00:18 But you don't have to. You can start in the middle. You can start in the bottom.

    00:21 Whatever is comfortable for you, but I kind of get -- I'm a creature of habit. I like to start at the top.

    00:26 So, which of them don't have a nucleus? So I'm going to say, "Does the white blood cell have a nucleus?" Oh, yeah, they're the ones that have like -- they even have PMNs, the polynuclei.

    00:38 They have lots of them, so I'm going to eliminate A.

    00:42 What about basophils? Do they have nucleus? Yeah, they do.

    00:46 What about platelets? Do platelets have a nucleus because I'm looking for the one that doesn't have a nucleus? They do.

    00:55 So, I'm left with red blood cells.

    00:57 I sure hope that's the right answer, because I've eliminated all 3.

    01:01 Red blood cells, do they have a nucleus? No, they don't.

    01:06 Remember, red blood cells are just like a sack for carrying around the hemoglobin.

    01:11 So the correct answer is D.

    01:13 Now, once I've eliminated 3, I have my final answer.

    01:18 You go back up to the stem of the question and say, "Does this make sense?" When I look at this, and I say, "Which of the following cells in the blood do not have a nucleus?" Right. I agree. "Red blood cells" is the right answer.

    01:33 Okay. We're done with the warm up.

    01:35 Now let's go to some serious questions.
