Chloroplasts - found only in plants and algae. they convert solar radiation energy to chemical energy usable for the cell's metabolism.
mitochondria - found in both plants and animals, they produce energy (in the form of ATP - chemical compound) by decomposing sugars and fats. they use up oxygen to do it.
MRNA or messenger RNA. As the central dogma of biotech goes, DNA is transcribed to mRNA which is translated to tRNA, after which the amino acids form peptide bonds and form proteins. So when you see transcription, the first thing you think of is DNA to mRNA.
Answer: A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1).
