Question

Item 3 If part of the DNA gene being transcribed is TGCAAT , what will the mRNA code be for that part?

Answer 1

Answer:

ACGUUA

Explanation:

Transcription is a process that makes mRNA using the DNA template strand. The enzyme RNA polymerase adds ribonucleotides complementary to the sequence of the DNA template strand. RNA lacks the "thymine" and instead has the "uracil". Adenine base in the DNA sequence is transcribed into the “uracil" base in the corresponding RNA. Similarly, "guanine" in the DNA template strand specifies the "cytosine" base in the transcribed RNA.  

Therefore, if a DNA template strand has a sequence "TGCAAT", the corresponding mRNA would have a sequence of "ACGUUA".
