Question

transcribe this dna sequence into mrna (remember that thymine is replaced by uracil in mrna) aat - cga - act (1 point) uua - gcu - uga tta - gct - tga aau - cga - acu ggc - uag - guc

Explanation:

In transcription, DNA bases pair with complementary RNA bases. Adenine (A) in DNA pairs with Uracil (U) in mRNA, Thymine (T) pairs with Adenine (A), Cytosine (C) pairs with Guanine (G), and Guanine (G) pairs with Cytosine (C).
For the DNA sequence AAT - CGA - ACT:

• AAT: A (DNA) → U (mRNA), A (DNA) → U (mRNA), T (DNA) → A (mRNA) gives UUA.
• CGA: C (DNA) → G (mRNA), G (DNA) → C (mRNA), A (DNA) → U (mRNA) gives CGU.
• ACT: A (DNA) → U (mRNA), C (DNA) → G (mRNA), T (DNA) → A (mRNA) gives UGA.

Answer:

UUA - CGU - UGA (First option)
