Answer:
New cells take the place of old or damaged cells as they die. Cancer disrupts this process and leads to abnormal growth in cells. It's caused by changes or mutations in DNA. DNA exists in the individual genes of every cell.
Explanation:
When more calcium moves into cells,less lead can go on.
Answer:What do banding patterns indicate?
Banding patterns are patterns of light and dark transverse bands on chromosomes. The light and dark bands become apparent by staining the chromosome with a chemical solution and then viewed under a microscope. These bands describe the location of genes on a chromosome.
Explanation:
Why are banding patterns important?
Banding Patterns Reveal the Structural Details of Chromosomes. Without any treatment, structural details of chromosomes are difficult to detect under a light microscope.
What does each stained band represent?
bands are the horizontal "bars" which are actually stained DNA molecules embedded in the gel. As the DNA molecules migrate through the gel, they are sorted according to their molecular weight, so that each band represents DNA of a specific molecular weight.
