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

When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of _____, which means
nordsb [41]

a. parsimony; simplest; fewest

When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.

Explanation:

Phylogeny describes the evolutionary history of on organism or group of organisms.  

A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.  

The Principle of Parsimony is best applied while constructing phylogenetic tree.  

This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.  

This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.
