Mutation is the primary cause of all genetic variation. Mutation is important as the first step in evolution, as it produces a new sequence of DNA for a particular gene, producing a new allele. Recombination, through intragenic recombination, may also generate a new DNA sequence (a new allele) for a particular gene.
Answer:
option A
Explanation:
In Recombinant DNA technology which involves DNA molecules formed by recombination to bring together genetic material from different sources, producing sequences that would normally not be found in the genome. Some basic steps are to be followed in the formation of your recombinant DNA. The restriction enzyme used in cutting the gene of interest from the pine tree DNA should also be the same used in cutting open the plasmid to make complementary sticky ends. Then integration of the isolated gene of interest into the cut plasmid and then this is treated with ligase to join the cut sticky ends. This construct is then introduced into bacterial cells.
The role of the liver in waste removal is to filter urea out of the blood and into the bladder. Thus, option A is correct.
<h3>What is liver and its function?</h3>
The liver is a very important organ of human body and the weight of liver is 1.5 kg and width of liver is 15 cm. The colour of liver is reddish - brown.
The main functions of liver are it carries out the function of protein's metabolism and it excretes bile and it is also responsible for excreting cholesterol, hormones, bilirubin and drugs.
The liver also stores vitamins, glycogen, and minerals so it the center of storage also.
As liver is a very important organ so to maintain it's health a person have to maintain a healthy weight, take a balanced diet, regular exercise, avoiding toxins, and less use of alcohol leads to keep the liver safe and healthy.
Therefore, the role of the liver in waste removal is to filter urea out of the blood and into the bladder. Thus, option A is correct.
