The options of the given question are:
method for DNA delivery
gene construct
efficient selection strategy
tissue culture system
Answer: Tissue culture system.
Explanation:
The role of tissue culture system is not much in case of the transgenic plant. The method of DNA delivery, efficient selection strategy and gene construct are involved in the plant transformation.
But plant tissue culture is not directly involved in the plant transformation. The plant tissue culture is the collection of the techniques which is used to maintain the growth of the plant cells and so it does not plays any important role in plant transformation.
The plant transformation is the introduction of the desired characters into the plant and then the growth of transformed plant takes place in the culture medium. This has no role in the plant transformation or has less role.
The correct order of steps in a gram staining procedure is:
(4) the specimen is treated with a stain called crystal violet.
(1) iodine is added as a fixative or mordant.
(3) the specimen is flushed with alcohol to dehydrate peptidoglycans and trap the stain.
(2) the specimen is treated with a stain such as safranin or fuchsin (a pink stain)
Gram staining is a common staining technique which helps to classify the bacteria into two categories: Gram positive and Gram negative. Gram positive bacteria appear violet in color and Gram negative bacteria appear to be pink. This color difference appears due to the difference in the bacterial cell walls.
