उत्तर
- Transcription is the process of synthesis of mRNA from DNA. It takes place in the presence of RNA polymerase.
- During transcription, mRNA is produced as per the sequence of nucleotides present on the DNA.
- This mRNA sequence is always complementary to the DNA strand that is used for its synthesis.
- The thymine in DNA molecule is replaced by uracil in RNA, during the process of transcription.
