Question

Durante la expresión génica, el ADN se transcribe en ARN en el núcleo. Luego, el ARN se traduce en proteínas en el citoplasma. ¿A través de qué barrera física debe pasar el ARN cuando pasa del núcleo al citoplasma?

Answer 1

Transcription is the process in which the DNA sequence of a gene is copied (transcribed) to make an RNA molecule.
RNA polymerase is the main transcription enzyme.
Transcription begins when RNA polymerase binds to a sequence called a promoter near the start of a gene (directly or through auxiliary proteins).
RNA polymerase uses one of the DNA strands (the strand or template strand) as a template to make a new complementary RNA molecule.
The transcript ends in a process called termination. The termination depends on sequences in the RNA that signal the end of transcription.
