Question

An astrobiologist discovers a new form of life on another planet. Life here appears to have evolved using DNA as the information storage molecule and proteins to carry out cellular function, much like on Earth, however the individual building blocks on this planet are different. On this planet, there appear to be 3 different nucleotides in the DNA and 30 different amino acids in the proteins. 

 

Which of the following conclusions about this form of life would be most justified?

These organisms can produce proteins no more than 30 amino acids in length.

These organisms must produce 30 different forms of mRNA

Amino acids must be coded by sets of 3 nucleotides in the DNA of the organisms on this planet.

Amino acids must be coded by sets of at least 4 nucleotides in the DNA of the organisms on this planet.

These organisms cannot produce more than 30 kinds of protein.
