A DNA sequence that is responsible for the initiation of transcription in a cell-type specific manner is:.

Promoter.

Explanation:

It is promoter because Promoter is a DNA sequence where's the gene transcription begins. It is the

DNA sequence which RNA polymerase binds or join to

so as to begin transcriptionn of a gene . It is a region where the regulatory elements i.e protein will bind to and the Promoter sequences are found directly upstream or at the end of 5' of the transcription initiation site. This can also encode RNA such as mRNA, trans and so on.

not too sure maybe olecranon process

i think the answer is gold im not entirely sure
