MRNA section
UGA UUG
Identify the DNA segment from which this section of mRNA was transcribed.
To identify the DNA segment from which the section of mRNA was transcribed, you need to perform a process called transcription, where the mRNA is synthesized from the DNA template strand. During transcription, the mRNA molecule is complementary to the DNA coding (non-template) strand.
Since there is no T base in the provided section of mRNA, we can deduce that the complementary DNA segment would contain an A base instead. Therefore, the DNA segment from which this section of mRNA was transcribed would be:
