Many drugs used to treat cancers inhibit DNA replication, whereas some will inhibit the pathways required to synthesize proteins from certain genes. Which one of the following accurately describes a step leading from DNA replication to the synthesis of a protein?
选项：

A:Translation of a gene generates a single-stranded RNA that is complementary to both strands of the DN
A:
B:Transcription of a gene generates a single-stranded RNA that is complementary to one of the DNA strands.
C:tRNA encodes the proteins during translation.
D:mRNA encodes the proteins during transcription.
E:rRNA encodes the proteins during transcription.
