Answer:
The two important conditions that must be met before gram staining are-
1. The age of the culture should not exceed 24 hours.
2. Over heating, decolonization should be avoided.
Explanation:
Gram staining is a technique developed to distinguish the bacteria on the basis of the composition of the cell wall around the bacteria.
The gram stain is a sensitive technique so must be performed carefully. The precautions should be taken to avoid any error while gram staining that is-
1. Age of the culture- The culture should be freshly prepared just 18-24 hours before the experiment as above 24 hours bacteria lose their ability to retain the color so one would not be able to differentiate between the cultures.
2. While performing the experiment one should avoid overheating and decolorization with ethanol as both the factors lead to the loss of crystal violet stain from the cell and they take pinkish color after safranin staying.

Explanation:
tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.
The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.
