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?

It is unique to Arabidopsis.
It is likely involved in a universal metabolic function.
It is a transgene.
There is not enough information to conclude anything.
It is part of a large gene family.

Answer #1

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...
