Answer: DNA is a double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins. It's found in the nucleus of the cell.

Explanation: Basically, if you look at DNA, you'll see that it has two strands which seem to twist (making it a helix, hence the term "helical"). If you uncoiled a strand of DNA, it would look like a ladder. The "rungs" of the ladder are called base pairs (adenine-thymine, guanine-cytosine) held together by a hydrogen bond. A goes to T, and G goes to C.

Gemiola [76]

The plasma membrane of the enveloped alga cell serves as the source of the apicoplast's second outermost membrane.

<h3>Where did all chloroplasts come from?</h3>

Chloroplasts were first established in eukaryotes through an endosymbiotic relationship with a cyanobacterium; they later spread through the evolution of eukaryotic hosts and the subsequent engulfment of eukaryotic algae by formerly nonphotosynthetic eukaryotes.

<h3>How did eukaryotic cells develop mitochondria and chloroplasts?</h3>

Chloroplasts and mitochondria most likely developed from engulfed bacteria that once existed as autonomous organisms. An aerobic bacterium was eventually swallowed by a eukaryotic cell, which later established an endosymbiotic bond with the host eukaryote and gradually transformed into a mitochondrion.
