How do proteins bind to DNA? Each DNA sequence that contains instructions for making a protein is known as a gene. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, the complex molecules that do most of the work in our bodies. How do proteins … Read more
How do you find the surface area ratio? To calculate the S/V ratio, simply divide the surface area by the volume. We will examine the effect of volume, shape, flatness, and body elongation on surface-to-volume ratios. To perform this function efficiently, there must be an appropriate ratio between the volume of the cell and its … Read more
