In the Upstream Promoter of Some Human Genes, a Regulatory

Multiple Choice

In the upstream promoter of some human genes, a regulatory sequence of eight nucleotides, TGACGTCA, has been shown to regulate a number of cAMP responsive genes. Based on this knowledge, you conduct a genome search and identify 250 of these identical sequences that occur. Could you then conclude that these sequences coincide with genes that are cAMP responsive?

A) Yes, because each of those regulatory regions containing that sequence would only be found near genes.
B) Yes, because this sequence would be unlikely to occur randomly.
C) No, because this sequence, in the context of 3 billion base pairs, would occur fairly regularly and may or may not be associated with a gene.
D) No, because there must be other regulatory sequences present as well.
