A scientist evaluated a sample of DNA and found that it contained 30% Cytosine (C). How much Guanine (G) must the DNA contain?
30% - Cytosine (C) always pairs with Guanine (G) therefore they must be found in equal amounts.
400
What is the name of the X-shaped structure in the picture:
Chromosome

DNA: AAA GGC CGA
AA: ?
DNA: AAA GGC CGA
mRNA: UUU CCG GCU
AA: Phe- Pro- Ala

Which fragment of DNA is the largest?
E
500
A scientist evaluated a sample of DNA and found that it contained 30% Cytosine (C). How much Adenine (A) must the DNA contain?
20% - Cytosine (C) pairs with Guanine (G). Guanine must also be 30%. 30% + 30% = 60%, that leaves 40% left for Adenine (A) and Thymine (T). 40%/2 = 20%

The phrase "The cat sat and the dog ran" is being used to represent a DNA sequence. Which altered phrase would represent a frameshift mutation?
A) the sat and the dog ran
B) the cat saa ndt hed ogr an
C) The dog sat and the cat ran
D) the cat sat cat sat and the dog ran
B) the cat saa ndt hed ogr an
the "T" was deleted from "sat" shifting all letters to the left
