Question

The liver of a dog has been found to have higher than normal cell death because the dna is damaged. What part of the cell failed to do its job of protecting the dna of the cell

Answer 1

Nuclear Envelope

Step-by-step explanation:

The Nuclear Envelope

The nuclear envelope is a membrane that surrounds the nucleus and offers an extra layer of protection to it. This extra layer provides an important barrier from potentially harmful bacteria, enzymes, and pathogens. It’s necessary to protect the nucleus, given that it houses the cell’s only copy of DNA; if that were to become damaged, the cell could die or produce damaged or inviable daughter cells when it comes time for cellular reproduction.

Answer 2

This is a slightly vague question because there are many reasons why DNA can be damaged and determining which organelle was at fault is generally a case by case matter. but the only part of a cell that you could considered to be tasked with protecting genetic material is the nuclear envelope which is simply a phospholipid bilayer surrounding the nucleus and/or the nucleolus so I would say the answer is the nuclear membrane and/or nuclear envelope.
