5. What is the size of a fully processed mature mRNA? Assume a poly(A) tail of 250 bp in your calculations. SHOW WORK. Exon 1 Intron 1 Exon 2 Intron 2 Exon 3 Intron 3 Exon 4 150bp 950 bp 250 bp 600 bp 199 bp 1400 bp 200 bp 6. For this experiment, RNA was extracted from either the nuclei or the cytoplasm of hen oviduct cells. The left lane shows mRNA from the cytoplasm and the right lane shows mRNA isolated from the nucleus. EXPLAIN these results based on what you know of eukaryotic transcription.

10. DNA mRNA tRNA / Amino Acids 11. Transcription takes place in the (nucleus/cytoplasm). 12. tRNA is used in (translation/transcription). 13. tRNA uses (anticodons/codons) to match to the mRNA. 14. Proteins are made at the (nucleus/ribosome). 15. (tRNA/mRNA) brings amino acids to the ribosome. 16. tRNA is found in the (nucleus/cytoplasm). 17. (Translation/Transcription) converts mRNA into a protein. 18. Translation takes place in the (cytoplasm/nucleus). 19. (DNA/RNA) can leave the nucleus. 20. (Translation/Transcription) converts DNA into mRNA.
