Homework Answers
1.Option C is the answer.
Recent studies in Antarctica found that double strand DNA plasmid,has ability to transfer on it's own from one cell to another.
2.Option C is the answer.
polycistronic mRNA is mRNA which can produce multiple proteins upon translation,thus coding for different genes.

Please help with 1-16!!! (two pictures are attached) Thanks!
Transcription . Although both prokaryotes and eukaryotes put a cap and a tail on the mRNA, only eukaryotes have introns that have to be spliced out. (T/F) 2. The poly A tail on cukaryotic mRNA protects the RNA from rapid degradation in the cytoplasm. (T/F) 3. The polyA tail is added to eukaryotic mRNA immediatel after transport of the message from the nucleus. (T/F) 4. is usually a single stranded molecule....
