Protein synthesis is vital for cell growth and metabolism. Transcription and translation are known as the central dogma of biology in which proteins are synthesized from DNA. How is transcription similar to translation in terms of base pairing?
Responses
A in transcription, RNA is formed; in translation, a polypeptide is formedin transcription, RNA is formed; in translation, a polypeptide is formed
B transcription starts at the promoter; translation begins at the start codontranscription starts at the promoter; translation begins at the start codon
C in transcription, DNA binds to mRNA; in translation, codons bind to anti-codonsin transcription, DNA binds to mRNA; in translation, codons bind to anti-codons
D in transcription, C pairs with G and A pairs with T to make mRNA; in translation, A pairs with U and G pairs with C to make tRNA
B transcription starts at the promoter; translation begins at the start codon
