It is mRNA because RNA, which stands for ribonucleic acid, is a polymeric molecule made up of one or more nucleotides. ... During the process known as transcription, a RNA copy of a segment of DNA, or messenger RNA (mRNA), is made. This strand of RNA can then be read by a ribosome to form a protein.
Thin, flexible barrier around a cell; regulates what enters and leaves the cell
- contains the cytoplasm (all interior cell organelles and the cytosol) - allowing the chemical reactions in the cell to occur
<span>- semipermeable (or selectively permeable) - allows certain substances in, keeps others out </span>
<span>- offers limited protection</span>
The best answer is B.
The endosymbiotic theory states that mitochondria and chloroplasts have striking similarities to bacterial cells:
1. they have their own DNA, which is separate from the DNA found in the nucleus of the cell.
2. Both organelles use their DNA for to produce many proteins and enzymes required for function.
3. They are both surrounded by a double membrane.
4. They reproduce just the way bacteria do, replicating their own DNA and directing their own division.
