Cultures of a bacterial species were incubated on the shelf of a refrigerator (5 C), out on a lab bench top (22 C), on the shelf
Setler79 [48]

D) Psychrotrophs.

Explanation:

  • Psychrotrophs are those bacteria which can tolerate cold temperature and have optimum growth above 15 degree Celsius.
  • Halophiles prefer high salt concentration.
  • Mesophiles prefer temperatures with a average of 37 degree Celsius.
  • Anaerobes grow in absence of oxygen.
  • In the given experiment, none of the bacterial cultures were placed in saline or anaerobic conditions. So, the bacterial species is not an anaerobe or halophile.
  • Again the cultures did not show growth at 37 degree celsius so they are not mesophiles.
  • Maximum growth at 22 degree celsius and a little growth in refrigerator make it obvious that the species is a Psychrotroph.

Which best summarizes the process of protein synthesis?
Tpy6a [65]

Answer:

RNA moves the DNA code to the ribosomes for protein synthesis

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA genetic message and assembles the brand-new polypeptide chain. tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
