Answer:
A combination of polypeptides and modified sugars that enclose the entire eubacteria.
Explanation:
A component of bacterial cell walls called peptidoglycan (PGN) promotes innate immune responses. Peptidoglycan, a polymer made of sugars and amino acids, creates the cell wall of the majority of bacteria by producing a layer that resembles a mesh outside the plasma membrane. N-acetylglucosamine and N-acetylmuramic acid residues are alternated in the sugar component. forms a saccules in the cell wall of most bacteria that resembles a bag. It controls bacterial cell shape and is crucial for osmotic stability. A heteropolymer made up of glycan strands carrying small peptides is known as a peptidoglycan.
Answer:
Letter E - exons are cut from the strand and removed
Explanation:
Letter A and B are incorrect because the poly-A tail and guanine cap are added to the 3’ and 5’ end respectively. They aid in translation of the mRNA, while serving as protection. The poly-A tail is repeated adenine nucleotides, while the guanine cap is a modified guanine nucleotide.
Letter C is incorrect because alternative splicing is one mechanism for generating variation, and is thought to be one of the reasons for why humans have smaller genomes than other organisms and still maintain high complexity. Alternative splicing is incredibly important because it produces more than one transcript from a pre-mRNA.
Letter D is incorrect because introns are the non coding portions of the mRNA. They are excised to make a smaller mRNA transcript, and one that contains all the protein genes.
This letter E is the correct answer, because exons are the coding portions of the mRNA, and are not excised during RNA processing.

Answer:
Griffith concluded that the R-strain bacteria must have taken up what he called a "transforming principle" from the heat-killed S bacteria, which allowed them to "transform" into smooth-coated bacteria and become virulent.
