Answer:
The best answer to the question, given the research found on this particular process in E. Coli specifically, would be: D) It identifies hemimethylated base pairs and methylates the unmodified base.
Explanation:
According to research on this pretty complicated topic, in E. Coli specifically, and other gram negative prokaryotes, it has been found that the presence, or absence of methylation will initiate MutS, which is a protein both in prokaryotes and eukaryotes responsible, in a full complex, of initiating and carrying out the full mechanism of DNA mismatch repair. As the daughter DNA strands are produced from parent strands, these first ones arise with several deletions and mismatches which need to be repaired and they are recognized due to the fact that daughter strands are hemimethylated. This circumstance activates MutS in E. Coli, who will then bind to the DNA strand that needs to be repaired and together with other members of the complex, like MutH and MutL, begin the process of repair.
In eukaryotes and other prokaryotes, the exact process by which DNA is repaired by MutS is still not totally known.
The best answer would be letter D. C<span>ompare the average number of tomatoes that are produced by 10 tomato plants that are grown in clay soil to the average number of tomatoes that are produced by 10 tomato plants that are grown in sandy soil.
It would be best to grow more than one tomato plant in each soil to truly represent the tomato's growth in them. To average the number of tomatoes yielded by each soil sample would also allow a sample that is more representative of the tomato plants than merely comparing single tomato plants.

Answer:
True
Explanation:
A plane mirror always forms a virtual image (behind the mirror). The image and object are the same distance from a flat mirror, the image size is the same as the object size, and the image is upright.
Answer:
A. Column 1
Explanation:
The information in column 1 is correct for all galaxy but information in coulmn 2 and Column 3 has some incorrect information about Elliptical galaxy.
Information about spiral galaxy is correct in all three columns that spiral galaxy has pinwheel shape and made up of several stars, dust and gas particles hold together by gravitational force.
Elliptical galaxy has round or oval shape and made up of mostly old stars and do not have much gas and dust particles which are hold together by gravitation force and not by electrical force.
Irregular galaxy has no defined shape as of spiral and elliptical and are made up of large amount of gas and dust and forms new stars which allow them to look brighter.
Hence, information in coulmn 1 is correct for all the galaxy.
Hello!
The correct answer would be A. A pie chart is best for percentages, a timeline is best for dates and history, a bar graph is better for set data, and a line graph is the best population changes and comparisons. I hope I helped!
