Types of DNA
Understand the Problem
The question is asking about different types of DNA, likely referring to the various forms that DNA can take, such as genomic DNA, mitochondrial DNA, and more. This inquiry could also touch upon their structures or functions within living organisms.
Answer
A-DNA, B-DNA, and Z-DNA
The final answer is A-DNA, B-DNA, and Z-DNA.
Answer for screen readers
The final answer is A-DNA, B-DNA, and Z-DNA.
More Information
A-DNA is right-handed and forms under dehydrating conditions. B-DNA is the most stable and common form found in living cells. Z-DNA is left-handed and can form under high salt conditions or negative supercoiling.
Tips
A common mistake is confusing the structural types of DNA with the two types found in cells (nuclear and mitochondrial DNA). Remember, A-DNA, B-DNA, and Z-DNA refer to the structure, not location.
