Answer:
The average size of the DNA fragments produced when this new DNA is cut by a restriction endonuclease with an eight-base recognition sequence would be 1679616.
Explanation:
Restriction enzymes can be described as the enzymes which are specific to certain DNA sites and cut the DNA from that particular site.
Normally, the average size of a DNA fragment cut by a restriction enzyme is calculated by the formula 4^{no.of base recognition sequence}.
As the number of bases has changed to 6 and the restriction enzyme has eight base recognition site then the formula will be:
6^{no.of base recognition sequence}
i.e
6^{8} = 1679616
Answer:
Carbon: basis for all living things, every living things contain this element.
Explanation:
Carbon is the element that is the major basis of all living things on Earth. Carbon occur natural on Earth. It represent 45 to 50% of total dry mass. Carbon is versatile and has ability to come stable bonds with other elements. Every biological molecules contain carbon. It is the main components of sugars, fats and proteins which are important biomolecules needed for living things proper cell functioning. It is the backbone of organic compound which forming living matter.
Answer:
Mhm
Explanation:
Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. This heat trapping is known as the greenhouse effect. ... Putting so much new CO2 into the air has made Earth warmer.
The essential molecule that comprises an average of 60% of any living organisms' cells is water. Water is a molecule made up of two hydrogen atoms and one oxygen atom. Water is an essential part that makes up the matrix of the inside and outside membranes of, for example, tissues in the human body. Water, to a certain degree, also helps maintain balance of electrolytes and solutes that go in and out of the cell. It also maintains hydrostatic pressure in the circulatory system of the body via the balance of Starling Forces. These are just a few examples of the importance of water and hence why living things need so much of them. This is also why water is one of the first things astronauts look for in planets to determine if life is possible there or if there was life before.
Other important elements that make living things are nitrogen (N) and calcium (Ca). To serve as a reference point, we can look at the human body. The amount of nitrogen (N) in the body is about 3.2%. Calcium (Ca) on the other hand, is about 1.5%
