Comments from Questionnaire What is the purpose of a DNA library? I'm not really sure how to go about figuring out how much 1X of the genome would be. How much what? Is this referring to nucleotides or contigs? What do you do think is the better option for everyday sequencing use in the real world: Dideoxy or shotgun genome? I don't understand the purpose of mates.
Shotgun Sequence of a Genome Drosophila genome (~100 million nt)
Shotgun Sequence of a Book Marley was dead, to begin with. There is no doubt whatever about that. The register of his burial was signed by the clergyman, the clerk, the undertaker, and the chief mourner. Scrooge signed it. And Scrooge's name was good upon 'Change for anything he chose to put his hand to. Old Marley was as dead as a doornail.

Shotgun Sequence of a Book Marley was begin wit dead, to be ad, to begi There is no doub Marley was dead …you would have to oversample a sequence for the shotgun approach to work?

Study Question 4What is high-quality sequence? Could you explain in more detail the fluorescence chart with the waves. To determine high quality sequences,… How do you know when a peak stops being high enough?
Dideoxy sequencing How sure are you? To determine high quality sequences,… How do you know when a peak stops being high enough?
For SQ3, I have been unable to identify the organism/molecule by using BioBIKE. I have tried the function SEQUENCES-SIMILAR-TO.
DNA replication Primer How to provide a primer to an unknown sequence?
Myers et al SQ6 primer primer Why read pairs? Scaffolds? What is the purpose of a DNA library? mates G A T C ~2000 nt insert plasmid
How to connect contigs primer Why read pairs? Scaffolds? Mate pairs dead, to begin with. There is no doub insert ~40 letters plasmid
Myers et al SQ6 ~ 150,000 nt . . . mates Why read pairs? Scaffolds? What is BAC used for again?. Bacterial Artificial CHROMOSOME Marley was dead. God bless us every one. I don't understand the purpose of mates.
