Answer:
Purple, spherical-shaped organisms arranged in chain like formations.
Explanation:
Bacteria are the microscopic organisms and included in the prokaryotes as they do not have nucleus. Two main types of bacteria are gram positive bacteria and gram negative bacteria.
The gram positive bacteria has thick cell wall peptidoglycan cell layer and can uptake the crystal voilet stain. These bacteria seems purple under the microscope due to the uptake of stain. The bacteria Streptococcus pyogenes are spherical in shape and occurs in the cluster of chain.
Thus, the correct answer is option (d).
The answer is mRNA. Translation is the process of reading the code in mRNA in the ribosomes to make protein. The ribosome is the organelle responsible for making proteins. The mRNA is translated from the language of nucleic acids (nucleotides) to the language of proteins.
