Best Answer: mRNA carries the transcribed genetic code tRNA carries the amino acids The ribosome translates the code on the mRNA and the appropriate tRNA comes in to affix the specific amino acid.t is synthized by complementary base pairing with DNA (transcription). mRNA is translocated from the nucleus to the cytosol. tRNA then base pairs with the mRNA. Attached to each tRNA is an amino acid (translation). The amino acids in a chain form a polypeptide.
Viruses (e.g., adenovirus, astrovirus, rotavirus, Norwalk virus) are the most common cause of diarrhea in the United States. The most common ones in children are rotavirus and in adults are norovirus. Escherichia coli, Clostridium difficile, and Campylobacter, Salmonella, and Shigella spp. are common bacterial causes.
Causes â Acute Diarrhea. Most cases of acute, watery diarrhea are caused by viruses (viral gastroenteritis). The most common ones in children are rotavirus and in adults are norovirus (this is sometimes called âcruise ship diarrheaâ due to well publicized epidemics). Bacteria are a common cause of travelerâs diarrhea.arasitic intestinal infections such as giardiasis can cause chronic diarrhea. Diabetes mellitus may be associated with diarrhea due to nerve damage and bacterial overgrowth; this occurs mainly in patients with long-standing, poorly-controlled diabetes.
