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.
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 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.
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 Sin a negative function or positive?
negative
Which the function's values become very positive or negative numbers?
The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero). The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).
What does the absolute value function do?
It removes the negative from a negative number making it positive and it does nothing to a positive number or zero.
Are high beams positive or negative on 1997 crown Victoria?
They need both a positive connection and a negative connection to function.
What is cos of a negative angle?
The cosine function is an even function which means that cos(-x) = cos(x). So, if cos of an angle is positive, then the cos of the negative of that angle is positive and if cos of an angle is negative, then the cos of the negative of that angle is negaitive.
Why negative numbers don't have logarithim?
The logarithmic function is not defined for zero or negative numbers. Logarithms are the inverse of the exponential function for a positive base. Any exponent of a positive base must be positive. So the range of any exponential function is the positive real line. Consequently the domain of the the inverse function - the logarithm - is the positive real line. That is, logarithms are not defined for zero or negative numbers. (Wait until you get to complex analysis, though!)
How would you explain to a seventh grader the difference between the domains of an odd root radical function and an even root radical function?
To start with, when you multiply an even number of negative numbers, the answer is positive. When you multiply an odd number of negative numbers, the answer is negative. When you multiply any number of positive numbers, the answer is always positive. For positive numbers, the value of a power is always positive. For negative numbers, the value of an odd power is negative, and the value of an even power is positive. Finding roots is the inverse of taking powers, so that an odd-root function can be evaluated for any value of x. An even-root function, however, cannot be evaluated when the value of x is negative, since an even power can never result in a negative answer. The domain of an odd root function is all real numbers; the domain of an even root function is the non-negative real numbers.
