In the process of transcription, the DNA sequence is transcribed to create mRNA. Each triplet of nucleotides in DNA corresponds to a codon in mRNA, where adenine (A) pairs with uracil (U), cytosine (C) pairs with guanine (G), and vice versa.
For the given DNA triplets ATG TCG:
- ATG transcribes to UAC (A becomes U, T becomes A, G becomes C).
- TCG transcribes to AGC (T becomes A, C becomes G, G becomes C).
This gives us the mRNA codons: UAC for ATG and AGC for TCG.
So the mRNA codons are: UAC AGC.
