Which statement is a feature of both prokaryotic and eukaryotic genes?
a. dna must be unwound from histone proteins before transcription of a gene takes place.
b. the nuclear membrane separates gene transcription and translation. genes are organized into operons.
c. one promoter controls a cluster of genes.
d. dna‑binding proteins influence the ability of rna polymerase to initiate transcription of a gene.

d: DNA-binding proteins influence the ability of RNA polymerase to initiate transcription of a gene

Explanation:

Transcription is the process through which RNA is synthesized using DNA as templates. It can also be described as a process during which the information contained in DNA is encoded as mRNA.

Transcription is an important process in both eukaryotic and prokaryotic cells and consists of 4 major steps:

There exist a number of similarities and differences in the transcription process of eukaryotic and prokaryotic cells. Few of these are;

The correct option is d.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
