The chain terminator method was used to sequence the following DNA fragment: ACTGGGCATAAGCGGGAACTTTGCAGAACTGGCTGGCCTCAGAGCAGGGA. 1. Predict a band pattern in a gel after sequencing this DNA fragment using a radioactively labeled primer [32P]-5’- TCTGAGGCCAGCCAGTTCTGCAAAGTTC. 2. Due to an experimental mistake, dATP was not added in all four reaction mixtures. How does the band pattern change?

A biochemist was able to sequence a DNA found in a human sample from humans who were first believed to settle in the Philippines. The sequence was identfied to be 3-TACTATTTGCGAGTACGCGATAT TGCATC-5'. 1. What is the complementary strand of sequenced DNA? 2. What is the transcription product of this DNA? 3. What is the sequence of the polypeptide that will be produced from this gene?
HgaI recognizes a specific 5 bp sequence. How frequently would you expect a specific 5 bp sequence to be found in any genome, considering that there are 4 possibilities for each of the 5 nucleotides in the restriction site sequence?
Restriction endonucleases are bacterial enzymes that cleave duplex (double-stranded) DNA at specific nucleotide sequences. The mode of replication of the animal virus SV40 has been investigated by using restriction endonucleases that cleave SV40 DNA into a number of unique segments. Like most viruses, SV40 DNA is circular. The map positions of the 11 fragments produced by a pair of restriction endonucleases are shown on the next page. Immediately following a 5 or 10 minute pulse of radioactively labeled thymidine, labeled SV40 molecules that have completed replication during the pulse are isolated. These newly replicated DNA molecules are digested by the restriction endonucleases and the resulting fragments are analyzed for the relative amounts of pulse label they contain. The results are in the table below. Assume that at the time the label was added there was a random population of replicating SV40 DNA molecules in all possible stages of synthesis. From the information given below,…
The restriction enzymes Kpn I and Acc 65I recognize and cleave the same 6-bp sequence. However, the sticky end formed from Kpn I cleavage cannot be ligated directly to the sticky end formed from Acc 65I cleavage. Explain why.
