Insertion Mutations and Reading Frame Shifts — NEET Biology
📚 Practice ConceptSimilarly, if we now insert two letters at the same place, say BI'. Now it would read,
Which of the following statements about DNA strands during transcription are NOT correct? S1: The strand that acts as a template for RNA synthesis has a 3'→5' polarity. S2: The coding strand is the DNA strand whose sequence is identical to the newly synthesized RNA, with the exception of thymine being replaced by uracil. S3: RNA polymerase reads the coding strand in a 5'→3' direction to synthesize RNA. S4: If both DNA strands were to act as templates simultaneously, it would lead to the formation of two RNA molecules with identical sequences. S5: The coding strand is identical in sequence to the template strand, only differing in the base thymine and uracil.
