Which statements belong to TRANSCRIPTION and which statements belong to TRANSLATION?   Type “CR” for Transcription or “LA” for Translation on the lines to identify the statements that belong to each process. Or type the full words if you don’t want to use the abbreviations.    Statements:  [BLANK-1] Terminationà  When the stop codon on mRNA gets into the ribosome’s A site, a release factor enters the A site and signals for everything to release.  [BLANK-2] When the amino acids + tRNA gets to the P site of the ribosome, the amino acid chain detaches from the tRNA and that amino acid chain will attach to the amino acid on the tRNA that entered in the A site.  [BLANK-3] Introns are removed by ribozymes because only exons are needed to code for the protein.  [BLANK-4] The ribosome shifts, the tRNA in the P site moves to the E site and exits, the tRNA in the A site moves to the P site, and a new tRNA with amino acid enters at the A site. [BLANK-5] The mature mRNA will exit the nucleus and find a small ribosomal subunit.  [BLANK-6] tRNA, ribosomal subunits, and mRNA separates.  [BLANK-7] The gene that needs to be expressed is located in the DNA. [BLANK-8] The process repeats until the mRNA has a STOP codon.  [BLANK-9] The tRNA and amino acid attach to the mRNA at the P site of the ribosome, and the large ribosomal subunit comes into place.  This is the initiation complex (mRNA + small ribosomal subunit + large ribosomal subunit + first tRNA with methionine).  [BLANK-10] RNA polymerase is the enzyme responsible for assembling the mRNA.  [BLANK-11] RNA polymerase locates the promotor sequence of the gene and begins assembling the mRNA at that point.  [BLANK-12] The process ends at the terminator sequence. [BLANK-13] The mRNA has a start = AUG, which signals for a tRNA molecule with the anti-codon and the corresponding amino acid, methionine.  [BLANK-14] The entire gene is transcribed into mRNA, which is primary mRNA.  [BLANK-15] Water snips the amino acid chain from the complex.  [BLANK-16] The complementary strand of DNA is transcribed into mRNA.  [BLANK-17] The mRNA triplets/codons code for tRNA with anti-codons to bring in the correct amino acids.  [BLANK-18] A 5’ cap and a Poly-A Tail are added to the mRNA.
