The complementary mrna strand synthesized from the dna sequence of ctgac would be

Answer;

GACUG

Explanation;

-Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps.

-First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes. The process relies on Watson-Crick base pairing, and the resultant single strand of RNA is the reverse-complement of the original DNA sequence. The pre-messenger RNA is then "edited" to produce the desired mRNA molecule in a process called RNA splicing.

-The nucleotides pairing follows the same base pairing rules as in DNA to form the correct sequence in the mRNA. However, during transcription, uracil (U) pairs with each adenine (A) in the DNA.

im back lol i heard you where asking for me
