Following statements were made regarding vulval development in C. elegans:

A. The formation of the anchor cell is mediated by lin-12, the C. elegans homologue of the Notch gene.

B. The formation of the anchor cell is mediated by lin-12, the C. elegans homologue of the Delta gene.

C. The lin-12 gene needs to function only in that cell destined to become the uterine precursor cell.

D. Presumptive Anchor cell also need lin-12.

E. Two cells originally synthesize both the signal for uterine differentiation (the LAG-2 protein, homologous to Delta) and the receptor for this molecule (the LIN-12 protein, homologous to Notch.

F. Only one cell synthesize both the signal for uterine differentiation (the LAG-2 protein, homologous to Delta) and the receptor for this molecule (the LIN-12 protein, homologous to Notch.

You are a scientist who is using genomics to currently study a new bacterial species that no one has ever studied before. The following sequence is a piece of DNA within the coding region of a gene that you have recently sequenced.

You are using shotgun sequencing to determine the DNA sequence of the genome of this new bacterial species. For one strand of a 30-nucleotide long stretch of DNA, you get the following sequences out of your shotgun sequencing reaction.

Choose correct 30-nt-long DNA sequence with the help of above-mentioned fragments
