DNA molecules are actually made up of nucleotides, which is the substance that is made up of three parts. Each nucleotide has a phosphate, a ribose sugar (five-carbon sugar) a â¦ nd a nitrogeneous base (purines-Adenine,Thymine or pyramidines-Guanine,Cytosine).NA is made up of a chain of molecules called 'bases' - Adenine, Guanine, Thymine and Cytosine.
Physical. Salmonella bacteria are rod-shaped gram-negative bacteria. Gram-negative bacteria do not retain the crystal violet dye used in the gram staining method due to the fact that they have cell walls that are thin.Gram-negative bacteria are often harmful to a host, which is the case for many of the Salmonella bacteria.Salmonella bacteria are between 2 and 5 micrometers long and 0.7 to 1.5 micrometers in diameter. They have flagella, which are tail-like projections made of proteins that help the bacteria to move.ram-negative bacteria do not retain the crystal violet dye used in the gram staining method due to the fact that they have cell walls that are thin.
