A certain bacterial mRNA is known to represent only one gene and to contain about
Brut [27]

Answer:

C) 30,000

Explanation:

According to the given information, the bacterial mRNA consists of about 800 nucleotides. Three consecutive nucleotides together make one genetic codon which in turn codes for one specific amino acid in the protein encoded by this mRNA.  

So, an mRNA with 800 nucleotides will have total 800/3 = 266.67 or 266 genetic codes. The protein encoded by this mRNA would have a total of 266 amino acids.  

Given that one amino acid imparts 110 units to the molecular weight of the protein, the protein with 266 amino acids have the molecular weight= 266 x 110 = 29260, that is about 30,000.

You are examining a rigid plant tissue; it does not flex or bend. Tests show that it is not consuming oxygen gas, as would be ex
siniylev [52]

Answer & Explanation:

The examined tissue could be cortex, due to the fact that it's rigid and does not require oxygen, so metabolic processes, like respiration, are not happening. The cortex, or wood, is dead tissue that no longer develops metabolic processes. It starts growing as the plan also grows, and the cambium tissue is in charge of this process.
