The best answer is C.
Plasma membranes are mainy made up of lipids and proteins. The lipids are glycerophospholipid, molecules composed of glycerol, a phosphate group and two fatty acid chains. Glycerol is a three-carbon molecule that functions as a backbone of these membrane lipids.
Within each glycerophospholipid, fatty acids are attached to the first and second carbon, while the phophate group is attached to the third carbon of the glycerol backbone.
Proteins such as glycoprotein are attched to the glycerophospholipids in the cell membrane. They are used for cell recognition and also act as receptors and antigens.
The nucleus is located in the center (approximately) of a eukaryotic cell. It is kept separate from the rest of the cell with a plasma membrane,
The chromosome is the one that carries the genetic information. The gene is the basic unit of heredity, meaning, this is the one that we carry from our parents. Genome is the collection of genes that is present in an organism. Therefore, if we arrange this from simplest to the most complex, the arrangement would be GENE, CHROMOSOME, GENOME.
Answer:
The human mitochondrial DNA (mtDNA) is a double-stranded, circular molecule of 16 569 bp and contains 37 genes coding for two rRNAs, 22 tRNAs and 13 polypeptides. The mtDNA-encoded polypeptides are all subunits of enzyme complexes of the oxidative phosphorylation system.
