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?
A)It is likely involved in a universal metabolic function.
B)There is not enough information to conclude anything.
C)It is unique to Arabidopsis.
D)It is part of a large gene family.
E)It is a transgene.
