Use the following information to answer the questions
below.
You have isolated a gene sequence from the mustard plant
Arabidopsis and have BLAST searched the NCBI database.
Your sequence hit several EST sequences that were identified as
transcription factors. These sequences were found in
E.coli, Chlamydomonas (a green algae), yeast,
mice, and humans and only had a few base pair differences.
What can be surmised about your transcription factor?

Correct option is second one.
Since, there are expressed sequence tags(EST's) of the gene of interest in several organisms ranging from the most primitive one to the recent ones. Therefore, we can conclude that the gene is most probably be involved in a universal metabolic function.

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
