What happens right after transcription ends? a. rna polymerase binds to the beginning of a gene. b. mrna detaches and moves to the ribosomes. c. the dna double helix unwinds. d. nucleic acids attach to the bases in the dna?

The answer is B: mRNA detaches and moves to the ribosomes.

Explanation:

Transcription is the process of formation of mRNA from DNA. DNA is the genetic material which carries all the information for the formation of mRNA and then protein. Transcription occurs in nucleus, but as soon as the mRNA is formed it unwinds from the template DNA stand and moves into the cytoplasm for the next process i.e. translation. Translation occurs near ribosomes (site of protein synthesis), it is the formation of protein from mRNA strand. Together both transcription and translation are called central dogma of molecular biology.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
