small amount of one of the four ddNTPs to four reaction tubes. You run the reactions in the
thermal cycler, load each reaction into a separate lane of a polyacrylamide gel, and separate
the products by gel electrophoresis. In the figure below, the lanes are labeled according to

Some Steps Involved in Creating Recombinant DNA
1. Plasmid DNA is cut at the restriction site.2. Foreign DNA is cut at the restriction site.3. Plasmid DNA is opened and sticky ends are formed.4. Foreign DNA restriction fragments are isolated5. Target sequence in the plasmid is recognized by the restriction endonuclease.6. Target sequences in the foreign DNA are recognized by the restriction endonuclease.7. Foreign DNA restriction fragment is inserted into the plasmid at the restriction site.8. DNA ligase splices the foreign restriction fragment and the plasmid together.

Part 3. Compare the Specificity of DNA-Cutting Tools
The flexibility and specificity of CRISPR-Cas9 technology offer a large step forward for gene editing.
The first DNA "scissors" were restriction enzymes, which cut DNA at predefined sequences, typically
4-8 base pairs long. For example, EcoRI, a restriction enzyme found in E. coli, will cut double-
stranded DNA at every GAATTC sequence. If EcoRI were added to a sample that contained the entire
human genome, it could cut at every GAATTC sequence.
We can calculate the probability that a particular nucleotide sequence, such as GAATTC, will occur
within a larger sequence. Table 1 below shows the calculated probabilities of finding sequences of
particular lengths. These calculations are based on the assumption that DNA sequences are entirely
random and that every nucleotide position has an equal probability of being A, T, C, or G. Use the
table to answer the following questions.

PCR analysis practice One 1) If you collect samples from crime scene and extract DNA out of each sample. Describe the technologies used to get the below results. 2) Identify which suspect is at the crime scene 3) Among suspect 1-3, who is homozygous for the tested locus and who is heterozygous?

The researchers want to determine if there is a mutation in a carabao farm that leads to high marbling of carabeef marbling. The researchers are knowledgeable and have unlimited funding. In their laboratory they have a PCR, a southern blot chamber and all the materials for DNA extraction. Propose a way to detect if there is a mutation in the carabao marbling.arrow_forward
