Biology 1st sem review Chargaff Rule

Chargaff's experiments showed that the amount of A, T, G and C is the same from species to species

• True
• False

If a section of DNA has 13% thymine, then there is _____ adenine

• 13%
• 26%
• 37%
• 74%

If there is 29% guanine in a section of DNA, then there is _____ thymine

• 21%
• 29%
• 42%
• 58%

The percentage of A + G equals _____.

• 26%
• 50%
• 80%
• 100%

Who said, "The amount of A = the amount of T, and the amount of G = the amount of C"?

• Chargaff
• Avery
• Griffith
• Franklin

If a DNA stand has 32 % guanine before semi conservative replication occurs, what percent thymine will each new strand have after replication? 

• 64%
• 32%
• 18%
• 36%

If a DNA stand has 32 % guanine before semi conservative replication occurs, what percent thymine will each new strand have after replication? 

• A = C
• A=C  & C=T
• A + C = G+T
• G+C = T +A
