Question

this model shows the process of transcription. which of these best explains the role of dna and rna in transcription? choose all that apply.
a rna is formed from dna nucleotides.
b dna serves as the template for making rna.
c rna copies a small segment of dna using rna polymerase.
d dna contains the entire genome, but in transcription, a small segment is copied into rna.
e dna contains the entire genome, and the entire genome is copied into rna that can travel to the ribosome.

Explanation:

Transcription is the process where RNA is synthesized using DNA as a template. RNA uses RNA nucleotides (not DNA nucleotides), so A is incorrect. DNA acts as the template (B correct). RNA polymerase catalyzes copying a small DNA segment into RNA (C correct). DNA holds the full genome, but only specific small segments are transcribed (D correct; E incorrect as the entire genome is not copied).

Answer:

B. DNA serves as the template for making RNA, C. RNA copies a small segment of DNA using RNA polymerase, D. DNA contains the entire genome, but in transcription, a small segment is copied into RNA.
