This is because the melanocytes are located in the stratum basale. Lighter-skinned people usually have low basal levels, and exposure to UV radiation causes an increase which makes skin darker.
A medical researcher measured the diastolic wall thicknesses of the arteries in a young, healthy test subject. The test subject came back 20 years later to have the measurements repeated. The measurements revealed that the subject's artery walls were half as thick as they were originally. Which of the following is the most likely long-term effect if the measured trend continues?
b) Arteries will be unable to withstand the pressure exerted by the heart, causing an aneurysm
Viral DNA can be inserted into the genome of bacteria by manipulating a specific enzyme known as DNA ligase.
<h3>What is DNA ligase?</h3>
This is a special enzyme found in humans and other forms of DNA. The role of the DNA ligase enzyme is to fuse together distinct strands of DNA. By manipulating this enzyme, scientists have achieved genetic modification.
Therefore, we can confirm that due to the successful manipulation of an enzyme known as DNA ligase, scientists have been able to insert viral DNA into the genome of bacteria.
