However, recent research seems to challenge certain aspects of Crick’s Central Dogma. Does the Central Dogma still stand today?

Transcription initiation begins when RNA polymerase bind to the transcription start site. B. RNA processing removes exons, adds a 3' cap, and adds and 5' tail. C. Translation terninates when a tRNA carrying methionine binds to a codon. D. The same amino acid may be encoded by multiple different 3-base codons.arrow_forwardHi, Could you please comfirm the following question. I have selected option c) because tRNA is the the complimentary pairs of mRNA so I figured the oppside end of the tRNA would be the same as the mRNA. When I have tired to double check my answer, no tutor has selected this answer. Thank you in advance, Like mRNA, tRNA has a ribose sugar, U instead of T, and is single stranded. Unlike mRNA, which remains a long single strand of nucleotides, tRNA folds so that some areas pair up. The resulting structure has an anticodon on one end and a site for an amino acid to attach on the other end. There is base complementarity (A pairs with U and G pairs with C) between an mRNA codon and tRNA anticodon.If the amino acid lysine attaches to a tRNA, which of the following anticodons could be at the opposite end of the tRNA molecule? a. UUU and UUC b. AGA and AGU c. AAA and AAG d. UCU and UCAarrow_forward
