Which statement best summarizes the process of transcription in cells?
A
Transcription is the process by which RNA is translated into a polypeptide chain.
B
Transcription is the process by which a DNA sequence is copied into a complementary RNA molecule.
C
Transcription is the process by which DNA is replicated to produce two identical DNA molecules.
D
Transcription is the process by which proteins are synthesized from amino acids.
Verified step by step guidance1
Step 1: Understand the definition of transcription in molecular biology. Transcription is the process where the genetic information in DNA is copied into RNA.
Step 2: Recognize that transcription involves creating a complementary RNA strand from a DNA template strand, meaning the RNA sequence is complementary to the DNA sequence.
Step 3: Differentiate transcription from other processes such as translation (RNA to polypeptide), DNA replication (DNA to DNA), and protein synthesis (amino acids to proteins).
Step 4: Note that transcription specifically refers to the synthesis of RNA from DNA, not the synthesis of proteins or replication of DNA.
Step 5: Conclude that the best summary of transcription is: 'Transcription is the process by which a DNA sequence is copied into a complementary RNA molecule.'
