what is located in DNA and signals the RNA polymerase to begin transcribing?

Answer 1

Transcription starts at a promoter, a base sequence in DNA that signals the start of a gene. Proteins help position an RNA polymerase on the DNA so it binds to the promoter. The enzyme then moves along the DNA strand, joining nucelotides one after another.

Answer 2

the initiator sequence is where the RNA polymerase attaches and does not transcribe that. it only transcribe the coding region. the terminator sequence tells the RNA polymerase to stop and detach.

EDIT: whoops, that gil above me is right, it's a promotor. i keep mixind it up with the process of the ribosome translating the mRNA to amino acids.

Answer 3

the be conscious nucleus potential kernel or center, and it comes from an historic greek be conscious meaning nut. as a time-honored rule, the nucleus is so extreme that the encompassing shape can't stay to tell the tale devoid of it. the nucleus is a small shape placed contained in the cells of eukaryotic organisms. the cellular nucleus is unquestionably between the defining traits of eukaryotes, because of the fact the form enables cells and organisms to realize an extremely extreme point of complexity. this shape devoid of the cellular is composed of the organism's DNA, and the nucleus is in charge for regulating gene expression, duplicating DNA as mandatory, and passing on hereditary traits, interior the case of egg and sperm cells. :)

Answer 4

enzymes. start and stop enzymes im pretty shure
