Which is true about eukaryotic gene regulation?

Answer 1

Most eukaryotic genes are controlled individually and have regulatory sequences that are much more complex than those of the lac operon.

(this answer above was found in my Biology text book too so it is correct) :)

Answer 2

Genes are regulated in eukaryotes through transcription factors and enhancer sequences. Transcription factors are proteins that bind to the DNA and in turn, help RNA polymerase bind to the DNA to start transcription. Activator molecules bind to the enhancer sequences that are many bases away from the promoter region. The different transcription factors and activator molecules in different cells control which genes are transcribed.

Answer 3

Eukaryotes have non-coding sequences in between the coding sequences (genes) called introns. This characteristic of the eukaryotic genome requires a more complex system gene regulation (or control over gene expression).

Answer 4

Individually. Prokaryote genes are controlled as groups.

Answer 5

Transcription factors regulate the expression of most eukaryotic genes. They are proteins that bind to specific DNA sequences, which controls the flow of genetic information.
