Answers:

1-4. D,B,A,C 5. DNA can not fit through pours in the nuclear envelope, and need to become single stranded to be used in the cell 6. Ribosome. 7. Double / single strands… RNA contains Uracil… RNA can leave nucleolus. 8. Chromosomes are DNA wrapped tightly. 9. A virus can insert coding into the DNA to have more of itself created by the cell. 10. Transcription changes DNA information to RNA. Translation changes RNA information into polypeptide chains. 11. 3 12. Codon is a collection of three bases on RNA. An Anticodon on the tRNA and matches a amino acid that matches the codon code. 13.
