A progressive approach to this task can be accomplished using the T-Coffee algorithm. For 10 points each:
[10h] Identify this task that can also be done using MUSCLE. MEME can be used to identify motifs in this task that can also be done via ClustalOmega.
ANSWER: sequence alignment [accept multiple sequence alignment; accept MSA; accept word forms like aligning DNA or protein or amino acid sequences]
[10m] Sequencing has revealed that this ancient group of genes that regulate body plan differentiation are widely conserved. Drosophila contains eight of these genes including lab and Ubx.
ANSWER: Hox genes [or homeobox genes; or homeotic genes]
[10e] Sequence alignments can be used to build phylogenetic trees, which can demonstrate that Archaea split off from this domain of life. Unlike prokaryotes, organisms in this domain have nuclei, including dolphins and yeast.
ANSWER: Eukarya [or Eukaryota; or eukaryotic; or eukaryotes]
