Answer:
DNA ligase
Explanation:
<em>The biochemist must have left out DNA ligase enzyme.</em>
<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>
The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.
Hence, the missing component is the DNA ligase.
Answer:
The given statements have been rearranged in the following order to depict the flow of events that account for lipid digestion in the human body:
- Mechanical digestion by chewing breaks food down.
- During digestion, gastric lipases break down fat into fatty acids and triglyceride molecules.
- Gastric lipase digests some triglycerides.
- The pancreas secretes gastric lipase into the small intestine, where the majority of fat digestion occurs.
- Lipid digesting enzymes from the pancreas break down the triglycerides into two free fatty acids and a monoglyceride.
- Lingual lipase is secreted from the pancreas and breaks down triglycerides.
- With the aid of pancreatic lipase, fats are further broken down into free fatty acids and monoglycerides.
- Products of fat digestion are packaged into micelles and transported to the enterocytes.
The process is started in the mouth. Action of the teeth physically breaks down the food and increases it surface area that allows for better access to it for the enzymes to carry out mechanical digestion. Gastric lipases are those in the stomach, most of the lipid digestion takes place in the small intestine with the help of enzymes secreted by the pancreas and the small intestine itself. After digestion, the final products are taken up by the lymphatic system.
Hope that answers the question, have a great day!
Answer:
Nanotechnology has bring up major advances in our everyday life. For example, the use of Nanobots that are extensively used now a days in medicine to make surgeries faster and accurate. By the use of nanotechnology, major problems like cancer can be treated by using cell by cell therapy. It is also utilized in curing genetic defects. Major drug designing and drug delivery has been made easier using nanotechnology.
Nanotechnology doesn't have any visible disadvantages but there always remains a fear like introduction of some extra contaminants and toxins in the environment. But mostly i agree with use of nanotechnology for the betterment. Furthermore we don't have any more advance techniques to fight problems than this technology.
cyanobacteria
it is one of the earliest organisms
