For each of the following items, state: "gram " if it is seen in just gram positive bacteria, "gram -" if it is seen just in gram negative bacteria, or "both" if it is seen in both gram positive and gram negative bacteria.
1) a cell wall that is made of peptidoglycan
2) a cytoplasmic membrane composed of phospholipids and protein
3) an outer membrane that includes lipopolysaccharide (lps)
4) a thick cell wall that causes the bacteria to be purple in the gram stain
5) teichoic acids and lipoteichoic acids embedded in the cell wall
6) a thin cell wall that causes the bacteria to be red in the gram stain

1)A cell wall that is made of peptidoglycan BOTH

2) A cytoplasmic membrane composed of phospholipids and protein BOTH

3) An outer membrane that includes lipopolysaccharide (LPS) GRAM-

4) A thick cell wall that causes the bacteria to be purple in the Gram stain  GRAM+

5) Teichoic acids and lipoteichoic acids embedded in the cell wall GRAM+

6) A thin cell wall that causes the bacteria to be red in the Gram stain GRAM-

Both of them have peptidoglycan layer in their cell wall, but the one in Gram + is thick (multilayered), while the one in Gram- is thin. This is the reason why the crystal violet dye retain in the walls of Gram + causing them to be purple (Gram – stay red). Gram- are more resistant against antibodies because of their impenetrable cell wall.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

answer; i believe the answer is (polygenic inheritance;
