What is the difference between negative supercoiling and positive supercoiling in DNA structure?
Negative supercoiling refers to the twisting of DNA in the opposite direction of its natural helical structure, resulting in a more compact and twisted form. Positive supercoiling, on the other hand, involves the twisting of DNA in the same direction as its natural helical structure, leading to a more relaxed and unwound form.

What is the difference between positive supercoiling and negative supercoiling in DNA structure and how do they impact gene expression?
Positive supercoiling in DNA structure refers to the overwinding of the DNA helix, while negative supercoiling refers to the underwinding. Positive supercoiling can hinder gene expression by making it difficult for enzymes to access the DNA, while negative supercoiling can promote gene expression by making the DNA more accessible.
What is the impact of negative vs positive supercoiling on DNA structure and function?
Negative supercoiling in DNA involves the twisting of the double helix in the opposite direction of its natural spiral, while positive supercoiling involves twisting in the same direction. Negative supercoiling helps in compacting DNA and promoting transcription and replication, while positive supercoiling can hinder these processes. Overall, negative supercoiling is more beneficial for DNA structure and function compared to positive supercoiling.
What are the effects of positive and negative supercoiling on DNA structure and function?
Positive supercoiling in DNA causes the molecule to twist tighter, which can help with gene regulation and compaction. Negative supercoiling, on the other hand, can lead to DNA strand separation and affect processes like transcription and replication. Both types of supercoiling play important roles in DNA structure and function.
How does positive supercoiling affect the structure and function of DNA?
Positive supercoiling in DNA occurs when the double helix is overwound, leading to increased tension and coiling. This can affect the structure and function of DNA by promoting tighter packaging, which can impact gene expression and DNA replication. Additionally, positive supercoiling can influence the stability of DNA and its ability to interact with proteins, ultimately affecting various cellular processes.
What is the difference between positive staining and negative staining based on the structure external to the cell wall?
positive stain stick with specimen and gives it's color where as negative dye doesn't stick with the specimen but settle around it's outer boundary and forming a silhouette. that negative stain produce a dark back ground around the cell.

Is the difference of a positive integer and a negative integer always negative?
No, because if the positive was 8, and the negative was -4, the difference would be positive four.
Is the difference of a negative integer and negative integer always a positive?
No, because if the positive was 8, and the negative was -4, the difference would be positive four.
