Respuesta :
In order for a eukaryotic gene to be engineered into a bacterial colony to be expressed, what must be included in addition to the coding exons of the gene (c) a bacterial promoter sequence
Explanation:
In Genetics, a promoter can be defined as a region of DNA where the process of transcription of a gene is initiated.
In the bacterial cell, the promoter region is present at the transcription start sites of genes ,on the upstream of the DNA and the process of transcription won't occur unless the promoter sequences is present.
Other options like introns are not required because introns are the non- coding sequences and they do not have any role to play in the expression of genes.
Promoters are an important component of expression vectors because they control the binding of RNA polymerase to DNA.
so, in addition to our desired code of exons, a bacterial promoter sequence must be attached for the expression of the genes.
