The unique characteristic of Gram-positive bacteria. Introduction: A Danish physician Hans Christian Gram developed a technique of staining that determines two groups of bacteria that differ from each other. Gram-positive and Gram-negative bacteria differ due to the differences in the peptidoglycan layer of the cell envelope. Cell envelope is composed of two or three layers that are cell membrane, cell wall and the outer membrane (in some bacteria).

To determine:

The unique characteristic of Gram-negative bacteria.

Introduction:

Bacteria are the prokaryotes that do not possess organelles. Their cell wall has peptidoglycan and they reproduce by binary fission. All bacteria possess cell membrane, cytoplasm, nucleoid, and ribosomes, but there are some specific structures that are possessed by some bacteria.

Students have asked these similar questions

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW). If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?

None

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
