Question

A scientist is studying the action of RNA polymerase during transcription. He wants to know what type of bases are added to the growing mRNA by RNA polymerase. A:bases complementaryto the template DNA. B:bases the same as those in the template . C:bases similar to the template DNA

Answer 1

The scientist wants to know what type of bases are added to the growing mRNA by the RNA polymerase then it would be bases complementary to the template DNA.

Step-by-step explanation:

Answer 2

During DNA sequencing, the codon created is paired by its complementary called the anticodon. The codon is made up of nitrogen bases. Adenine is paired with uracil; uracil paired with thymine, thymine paired with adenine, glycine paired with cystine. The answer is A.
