A phospholipid is a type of lipid molecule that is the main component of the cell membrane. Lipids are molecules that include fats, waxes, and some vitamins, among others. Each phospholipid is made up of two fatty acids, a phosphate group, and a glycerol molecule. When many phospholipids line up, they form a double layer that is characteristic of all cell membranes.
A phospholipid is made up of two fatty acid tails and a phosphate group head. Fatty acids are long chains that are mostly made up of hydrogen and carbon, while phosphate groups consist of a phosphorus molecule with four oxygen molecules attached. These two components of the phospholipid are connected via a third molecule, glycerol.
The process depicted in the diagram is transcription because it clearly shows that an mRNA is attached to the DNA . Since we can see that two bases G and A are not yet paired we can conclude that more Bases will be added to the mRNA.
DNA is a Double helix that has a complementary DNA strand thus we can guess that the mRNA is not the integral part of the molecule but it is being synthesised from the DNA.
The 3' end of DNA is unpaired and hints that the bases will be added to 3' end of the mRNA.
