X 08 Question 6 (3 points) 4) Loten 1080 Which of the following is/are true of the processing of the initial (primary) transcript of mRNA as it becomes the final transcript in eukaryotes? (Please select ALL that apply) the final transcript contains only exon elements Othough the primary transcript consists of RNA nucleotides, the final transcript consists of DNA nucleotides Da modified nucleotide (7mG) cap is added to the 5' end of transcript as it is being processed a string of guanine-containing nucleotides (poly-G) is added to the 3' end of the transcript as it is being processed # F acer 5 - Avagy ✔ 3 14 2 CARIN

11 12 24 15 30- Question 16 (3 points) Ustan Which of the following is/are true of the elongation phase of translation. (Please select ALL that apply) the polypeptide chain grows due to the formation of a peptide bond between amino acids in the "P" and "A" sites ORNA molecules can both interact with the mRNA transcript and add an amino acid to the polypeptide chain more than one type of mRNA codon can encode the same amino acid being added to the polypeptide every six RNA nucleotides in the mRNA transcript lead to one amino acid being added to the polypeptide only the small subunit of the ribosome is involved in the elongation phase of translation the elongation phase will continue until the codon "AUG" is read by the ribosome ad acer 44 5 55 20 1 - WEBCAM
