Question

Note about transcription: b/c of ____, the codons on the RNA strand will be complementary to the triplets on the template side and identical to the triplets on the opposing side, called the coding or sense side

Answer 1

Transcription results in mRNA codons that are complementary to DNA template strand triplets and identical to DNA coding strand triplets. Uracil in RNA replaces thymine in DNA, and these codons dictate amino acid sequence in proteins via translation.

Step-by-step explanation:

Because of transcription, the codons on the RNA strand will be complementary to the triplets on the template strand, and identical to the triplets on the opposite strand, known as the coding or sense strand in DNA. During the process of transcription, an mRNA strand is synthesized using the template strand of the DNA. The RNA nucleotides align opposite their complementary DNA partners, except that uracil (U) replaces thymine (T). For instance, if the DNA template strand has a sequence 5'-AATTGCGC-3', the resulting RNA strand would have the sequence 3'-UUAACGCG-5'. The mRNA codons are then used during translation to specify amino acids, with each codon corresponding to a single amino acid or a stop signal during protein synthesis. This complementarity allows the RNA molecule to accurately copy the genetic information from DNA and carry it to the ribosomes for translation.
