The correct answer is - B-DNA is the most common form of the DNA present in the cell and a good approximation of the structure of DNA in the cell.
Explanation:
The B- DNA is a form of the DNA that is explained by Watson and crick by the double-helical structure model. B-DNA is the predominant form of the DNA out of the three forms of the DNA which are B-DNA, Z-DNA, and A-DNA.
B-DNA is is provide a good approximation of the structure of DNA in a cell and its most common form of DNA in a cell that makes it the most studied and focused form of DNA.
Thus, the correct answer is - B-DNA is the most common form of the DNA present in the cell and a good approximation of the structure of DNA in the cell.
B-DNA is the helical form most commonly found in nature.
Explanation:
Even though there are three different helical forms of DNA, molecular biologist primarily focus on B-DNA because is the most commonly found in nature. A very small proportion of Z-DNA is found in negatively supercoiled DNA, and A-DNA is formed when the DNA is facing dehydrating conditions. However, B-DNA is the prominent and active form found in nature, therefore is the most studied.
The pattern of organization is used by the writers to organize their ideas to effectively communicate the message.
The pattern of organization used can vary depending on the purpose of writing a statement.
The organizational pattern that is used in the sentence "The three parts of an insect's body are the head, the thorax, and the abdomen" is a spatial pattern.
Spatial organizational pattern organizes the information given in a sentence based on the physical relation of objects with each other. This pattern of organization is widely used by the writers to strike up an image of how the various parts are physically located.
Since in the given sentence the head, thorax, and abdomen are located one after the other in a cockroach's body, the pattern of organization used is spatial.
