The dude on the top is right his answer is quite good!
Well I believe that
aside from the big ones which are the DNA and RNA:
Some
proteins (such as telomerase) have bits of attached RNA. Ribosomes have a bit
of RNA. <span>
<span>We also have adenosine triphosphate, which is the energy koin
of the cell. </span></span>
Bacteria<span> traits such share many common features, such as: A lack of membrane-bound organelles.
</span>
<span>XXY I believe is the answer</span>
The correct answer is D. Cell Membrane because the cell membrane contains two phospholipid layers with the protein molecules attached to them throughout.
Hope I helped! :)
