Question

cell piece #4, that part that uses dna to build all of the cells necessary parts, is...
a ribosome.
dna.
cytoplasm.
the plasma membrane.

Explanation:

Answer:

None of the above options are correct. The part of the cell that uses DNA to build all of the cell's necessary parts is the nucleus. If we must choose from the given options, the closest - related is a ribosome as it is involved in protein - synthesis using the information from DNA (but it is not the part that "uses DNA" in the overall sense of directing all cell - part building). However, if we assume no other options, the best answer from these would be a ribosome. So, A. a ribosome
