You are excited because your lab is studying the first microorganisms retrieved from Mars! Interestingly, their genetic material
Oliga [24]

Answer: The maximum number of amino acids that could be coded is 2

Explanation:

  • A codon in this microorganism is 2 bases instead of 3 bases .
  • In order to encode a protein a sequence requires a start and stop codon
  • If you assume no start codon: then only 2 bases would make up the stop codon.
  • This leaves 4 bases which is 2 codons. This would encode 2 amino acids.

  • If you assume a start and stop codon, then each codon would be allocated 2 base pairs each =  4 base pairs
  • This only leaves 2 base pairs, a single codon which would only code for 1 amino acid

Why does a hormone only act on specific cell types in an organism and not others?
Vilka [71]

Answer:

c) A cell must have the appropriate receptor before it can bind to the hormone.

Explanation:

Hormones are chemical signals that are secreted into the circulatory system acting as regulators within the body, and even though they can reach any part on the body, <em>only certain types of cells are equipped to respond, these cells are known as target cells, when the hormone reaches a cell with an adequate receptors it triggers a signal transduction and then a response.</em>

Therefore the correct answer is c.

I hope you find this information useful and interesting! Good luck!
