Which statements are true? Explain why or why not.1 The consequences of errors in transcription areless severe than those of errors in DNA replication.2 Since introns are largely genetic “junk,” they do nothave to be removed precisely from the primary transcriptduring RNA splicing.3 Wobble pairing occurs between the first positionin the codon and the third position in the anticodon.4 During protein synthesis, the thermodynamics ofbase-pairing between tRNAs and mRNAs sets the upperlimit for the accuracy with which protein molecules aremade.5 Protein enzymes are thought to greatly outnum-ber ribozymes in modern cells because they can catalyzea much greater variety of reactions and all of them havefaster rates than any ribozyme.

Hi, 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 UCA

Which statement is false: A) Each type of protein ( ex: hemoglobin vs trypsionngen) varies in the length and amino acid sequence of its peptide B) After the rpocess of transcription is complete, the mRNA that is produced will continue being tranlsated by ribosomes for the rest of the cells life. mRNA never breaks down C) A ribosome will bind to an mRNA and will translate the sequence by reading one codon at a time and adding one amino acid to the peptide chain. It will stop the translation once it encounters a stop codon D) The gene for a protein provides the information on the legth of the peptide, along w the amino acid sequence so the protein can be synthesized by a ribosome E) Once mRNA has left the nucleus, ribosomes will bind to it and will follow the instructions in its sequence to make the new protien
