How to use Chargaff s rule in order to solve DNA composition Chargaff's rules state that DNA from any cell of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA. Youtube video: https://lnkd.in/dc9WdaQj \#nikolays_genetics_lessons

Color blindness and ABO blood group inheritance problem and solution Color blindness occurs when you are unable to see colors in a normal way. It is also known as color deficiency. Color blindness often happens when someone cannot distinguish between certain colors. This usually happens between greens and reds, and occasionally blues. The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes. In human blood transfusions it is the most important of the 38 different blood type classification systems currently recognized.
