There are two possible reasons, and it may help enrich your digest concentrations by looking into these two possible solutions:
1. Incomplete digestion. The migration of an untreated plasmid travels faster that linearized DNA. The apparent band size of a circular DNA may be as much as 500bp smaller than its linearized counterpart.
2. Perhaps the agar wasn't fully melted when the gel was prepared. This can cause resolution problems, and sometimes a smear would show up.
3. The enzyme used is one of the more uncommon enzymes (noted by the volume the enzyme came in), and so these may be more picky at its turnover rate, leading to partial digestions.
Most of the time a restriction enzyme does its job really well if it was allowed to digest 1-2ug of DNA for at least 2 hours for NEB brand of enzymes. If it was just a diagnostic restriction digest, then you can predict what those bands would look like if it was a partial digest.
Good luck.
What else can I help you with?
Which enzyme would cut the plasmid without disrupting the function of?
Perhaps you mean a restriction enzyme, but not disrupting the function of whatever is not too clear. I think if you cut a plasmid with any restriction enzyme I am familiar with the function of that plasmid would be disrupted.
To produce a recombinant plasmid and the foreign DNA are cut with a different restriction enzyme?
When producing a recombinant plasmid, the plasmid and foreign DNA are cut with the same restriction enzyme(s) to generate complementary sticky ends for ligation. Using different restriction enzymes would create incompatible ends that cannot be ligated together effectively, making it difficult to form a functional recombinant plasmid.
What biochemical tool would be use to cut a plasmid?
Restriction enzymes would be used to cut a plasmid. These enzymes recognize specific DNA sequences and cleave the DNA at those sites. This allows for the insertion of desired DNA sequences into the plasmid.
Why do you need to cut the plasmid and cell DNA with the same restriction enzyme?
Cutting both the plasmid and the cell DNA with the same restriction enzyme ensures that they have complementary sticky or blunt ends, allowing for precise ligation. This compatibility is crucial for successful cloning, as it facilitates the insertion of the DNA fragment into the plasmid. If different enzymes are used, the ends would not match, preventing the two DNA molecules from joining effectively. Thus, using the same restriction enzyme increases the efficiency and specificity of the cloning process.
How does ligating the plasmid vector and P. putida DNA in the presence of a restriction enzyme increase recombination?
Ligating the plasmid vector and P. putida DNA in the presence of a restriction enzyme increases recombination by generating compatible ends on both the plasmid and the target DNA. The restriction enzyme cuts the DNA at specific sites, producing cohesive (sticky) or blunt ends that can easily anneal. When the plasmid vector and the P. putida DNA are mixed, these complementary ends facilitate the ligation process, allowing for more efficient insertion of the target DNA into the plasmid. This enhances the likelihood of successful recombination events, enabling the creation of recombinant DNA molecules.

Why is a restriction enzyme that cuts your plasmid more than once unusable?
If a restriction enzyme cuts a plasmid more than once, it may create multiple fragments that can't be easily re-ligated back together. This can result in a mix of different plasmid forms, making it challenging to obtain a pure, single-cut product for downstream cloning experiments.
What is the biochemical tool that scientists use to cut plasmid?
Scientists use enzymes known as restriction endonucleases to cut plasmid DNA at specific sequences. These enzymes recognize and cleave DNA at specific sites, allowing researchers to manipulate the plasmid for various genetic engineering applications.
What are some plasmid mapping practice problems with answers that can help in understanding the concept better?
One example of a plasmid mapping practice problem is to determine the restriction enzyme sites on a given plasmid sequence. Another practice problem could involve identifying the location of a specific gene or marker on a plasmid map. These exercises can help in understanding the concept of plasmid mapping by applying theoretical knowledge to practical scenarios. Answers to these practice problems can be found by analyzing the plasmid sequence and using bioinformatics tools to predict restriction enzyme sites or gene locations.
How can i know if my bacteria contain plasmid or not?
You can determine if your bacteria contain a plasmid by performing a plasmid extraction followed by gel electrophoresis to visualize the presence of plasmid DNA. Other methods include PCR amplification of plasmid-specific sequences or using molecular biology techniques like restriction enzyme digestion to confirm the presence of a plasmid.
What are some plasmid mapping practice problems that can help improve understanding and proficiency in plasmid mapping techniques?
Some plasmid mapping practice problems that can help improve understanding and proficiency in plasmid mapping techniques include identifying restriction sites, determining the size of DNA fragments, predicting the location of genes or specific sequences, and analyzing the results of restriction enzyme digests.
What must researchers know before they begin the process of gentic engineering?
you need to know which restriction enzyme to use. also, who is the doner and the plasmid.
What would happen if you cut both the jellyfish glo gene and puc18 plasmid with the ecor1 restriction enzyme?
If there is a EcoR1 site in either the middle of the Glo gene, or in the middle of the selectable marker site in the plasmid, it would likely disable either Glo, or the plasmid.
