A certain bacterial mRNA is known to represent only one gene and to contain about 800 nucleotides. If you assume that the average amino acid residue contributes 110 to the peptide molecular weight, the largest polypeptide that this mRNA could code for would have a molecular weight of about _______.
A) 800.
B) 5,000.
C) 30,000.
D) 80,000.
E) An upper limit cannot be determined from the data given
Answer:
c. 30,000
Explanation:
The gene has a total of 800 nucleotides and would be transcribed into an mRNA having about 800 nucleotides. The nucleotides of mRNA are read in the form of genetic triplets. This means that the mRNA with 800 nucleotides would have about 800/3= 266.66 or 266 genetic codes. This mRNA would be translated into a polypeptide chain having around 266 amino acids.
One amino acid contributes 110 to the molecular weight. The total molecular weight of the largest possible polypeptide that can be encoded by the said gene would b 266 x 110= 29260 (around 30,000).
There are three species of wolves: the Red Wolf, the Gray Wolf, and the Ethiopian Wolf.
There are a lot more subspecies of wolves, such as:
Mexican Wolf
Eastern Wolf
Maned Wolf
Arctic Wolf
Iberian Wolf
Eurasian Wolf
Alexander Archipelago wolf
Alaskan Wolf
Alaskan Tundra Wolf
Greenland Wolf
Kishida Wolf
Manitoba Wolf
Plains wolf
Timber Wolf
Tundra Wolf
I could come up with multiple examples!
•Coal
•Natural gas
•Nuclear energy
•Petroleum
Hope this helped!
Did you make a mistake? I don't really understand what you are asking, but if you post this again with proper pronunciation, I will gladly try to answer your question.
