Chapter 17.1, Problem 1LO
Summary Introduction
To describe: The way in which the ligases and restriction endonucleases are used to make recombinant DNA.
Introduction: Deoxyribonucleic acid (DNA) is the hereditary material present in humans and almost all organisms. It contains the genetic information required for the development and functioning of living organisms. A single DNA molecule formed using DNA from two different sources is called as the recombinant DNA.

b) Describe how DNA is digested by different restriction enzymes
c) Describe how gel electrophoresis is used to estimate the size of DNA fragments.
Describe how restriction enzymes like EcoR1 are used to create recombinant plasmids and what the process is for using these plasmids to replicate a piece of target DNA. Include information about how to create sticky ends, the makeup of the bacterial plasmid and how to tell if the gene was successfully inserted in the plasmid and if the plasmid has been transformed by the bacteria. You may use a drawing to enhance your description.
Explain what restriction enzymes are, how they function and how they can be used to make recombinant DNA

- Restriction endonuclease and ligase are two types of enzymes used in the process of genetic engineering, i.e., the manipulation of genes. The restriction endonuclease differs from ligase in that it breaks the DNA at ends, while ligase causes the breaks in DNA from interior joins the fragments of DNA, while ligase breaks the DNA into fragments breaks the DNA at specific points, while the ligase joins the fragments of DNA breaks the DNA apart at each nucleotide, while ligase use the pieces to translatearrow_forwardDescribe the role of restriction enzymes in the process of transformation.arrow_forwardCompare CRISPR-based endonucleases with restriction endonucleases.arrow_forward

Restriction maps are important when generating a construct for experimental use. Digesting the DNA sequence with the restriction enzymes will result in fragmented DNA of predictable sizes, based on the restriction map, that allow a researcher to analyze if his or her construct was generated correctly when visualized using gel electrophoresis. Use the linear restriction map to predict where bands would be expected on a gel if a digest is performed using the specified restriction enzymes. Assume that there is enough restriction enzyme that every possible restriction site on each molecule of DNA will be cut.arrow_forward
