Question: Please use the following information to answer the question(s) below. A group of six students has taken samples of their own cheek cells, purified the DNA, and used a restriction enzyme known to cut at zero, one, or two sites in a particular gene of interest.

Analysis of the data obtained shows that two students each have two fragments, two students each have three fragments, and two students each have one only. What does this demonstrate?

Answer:

"The two students who have two fragments have one restriction site in this region."

Explanation:

A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cuts DNA into trashes at or close precise appreciation sites inside particles identified as restriction locations. Restriction enzymes are one session of the wider endonuclease collection of enzymes. In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into minor trashes. The scratches are constantly made at exact nucleotide arrangements. Unlike restriction enzymes recognise and cut diverse DNA sequences.

Studying the folding patterns of protein molecules can help microbiologists better understand cellular processes as well as some

vivado [14]

The statement that best describes the work of these researchers is "As a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done." I hope my answer has come to your help. God bless and have a nice day ahead!

Compare and contrast the two new cells formed in mitosis and cell division

Makovka662 [10]

The parent cell is also making a copy of its DNA to share equally between the two daughter cells. The mitosis division process has several steps or phases of the cell cycle—interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis—to successfully make the new diploid cells
