Question

Scientists have found a new function of the nuclear membrane, the envelope that encases and protects DNA in the nucleus of a cell—it fixes potentially fatal breaks in DNA strands. Previously, the nuclear membrane was thought to be mostly just a protective bubble around the nuclear material, with pores acting as channels to transport molecules in and out. But a recent study has documented how broken strands of a portion of DNA known as heterochromatin are dragged to the nuclear membrane for repair. The reason why we don't experience thousands of cancers every day in our body is because we have incredibly efficient molecular mechanisms that repair the frequent damages occurring in our DNA.

The main idea of the passage is

Answer 1

a) to present the findings from new research .

Step-by-step explanation:

The term "main concept" refers to the idea that dominates a paragraph or phrase. Setting the tone of a paragraph or chapter is an important part of the writing process. Paragraphs often begin with a key idea, which is subsequently restated or emphasized at the conclusion.
