What is the primary purpose of transcription in eukaryotic cells?
A
To translate mRNA into a polypeptide chain
B
To replicate DNA before cell division
C
To modify proteins after translation
D
To synthesize an RNA copy of a DNA sequence
Verified step by step guidance
1
Understand that transcription is the process by which genetic information from DNA is copied into RNA.
Recognize that in eukaryotic cells, transcription occurs in the nucleus where an RNA molecule is synthesized using one strand of the DNA as a template.
Recall that the main product of transcription is messenger RNA (mRNA), which carries the genetic code from DNA to the ribosome for protein synthesis.
Differentiate transcription from other processes such as translation (which converts mRNA into a polypeptide) and DNA replication (which copies DNA before cell division).
Conclude that the primary purpose of transcription is to synthesize an RNA copy of a DNA sequence, enabling gene expression.
