Not exactly sure this is right .Bonking, or “hitting the wall” as it is also known, is a well-known phenomena among marathon and ultramarathon runners which occurs when your body runs out of sugar to burn. Sugar, stored in your liver and muscles bound into large chains called glycogen, is the prime fuel for a distance runner.
Explanation:
<span>The question says,' structurally DNA and RNA are similar although their three basic component differ slightly. One way DNA and RNA differ is in thier ............ DNA is a long chain polymer with deoxyribose and phosphate backbone, it has four different nitrogenous bases: thymine, adenine, cytosine and guanine. RNA is a long chain polymer with a ribose and phosphate backbone, it has four nitrogenous bases: guanine, cytosine, adenine and uracil.</span>
REMEMBER: color blindness is carried on the X chromosome only! The male has to inherit the mutated gene from his mom and her X chromosome to be color blind. Because the male has only 1 X, he has a greater chance to be color blind than a daughter who would have to inherit a bad X chromosome from each parent!
If you follow the family tree, the person 12 (the daughter of 4x5) could be either XX or XX (I'm using bold to indicate the color blind gene on the X chromosome). You cannot tell from this family tree what she is (except that we know her mom (4) is definitely a carrier!
So you need to do two potential crosses:
1. Daughter 12 is not a carrier; so she is XX
Cross XX with XY; you get the possibility of all daughters as carriers XX, or all normal sons XY.
2. Daughter 12 is a carrier; so she is XX
Cross XX with XY; you get the possibility of daughters that are color blind (XX), daughters as carriers (XX), color blind sons (XY) and normal sons.
