Explain how you would use a DNA microarray to compare the genes expressed in human brain cells with those expressed in human liver cells. The key difference between symmetric and asymmetric karyotype is that symmetric karyotype shows a smaller difference between the smallest and largest chromosomes in the set while asymmetric karyotype shows a larger difference between the smallest and largest chromosomes in the set. The outside of a DNA consists of alternating sugar (deoxyribose) and phosphate atoms whereas the interior "rungs" of the DNA "ladder" and consist of the either adenine, thymine, cytosine, or guanine. Using the database, it is straightforward to calculate the average chromosome length (L avg = L tot /2n) and the average DNA content per chromosome (c avg = 4C/2n). The benefit would be that people could access the information easier, the danger would be that anyone might be able to find the information.

The program should have as much security on it, as the white house does. Also, the chromosomes differ in size and the positions of the centromeres. The sex chromosomes of human beings and other mammals are designated by scientists as X and Y. DNA is shaped as a double helix and is made of nucleotides. Suppose that there is no atmosphere to get in the way of this one molecule bouncing up and down on the desk. A gene is therefore composed of many pairs of nucleotides. Thus, this explains the key difference between symmetric and asymmetric karyotype. Nirogenous base 3. A chromosome is a long strand of DNA which is coiled up with various proteins.
