Restriction enzymes (REs), which cut D NA at specific sequences, are classic tools in molecular biology. Because of their specificity in cutting DNA, REs can be used to "map" DNA sequences by analyzing the fragments generated upon restriction digest, as in the example shown in Figure 1. Your task is to study the circular plasmid, pMBBS, through restriction digests. You subjected the PMBBS plasmid to complete digestion by different combinations of three REs (EcoRI, BamHI, and Xhol), and analyzed the results on an agarose gel, shown below. Using the data you can glean from this gel, answer the questions that follow. EcoRI BamHI Xhol DNA size ladder 600 bp 500 bp 400 bp 300 bp 200 bp 100 bp VC 100bp Plus DNA ladder from Vivantis Technologies *The same total amount of DNA was loaded in each lane. 1. What is the total size of the PMBBS plasmid in bp? Answer: bp 2. How many cut sites on the PMBBS plasmid does each RE have? EcoRI: BamHI: Xhol: 3. If the pMBBS plasmid were digested with all three REs together, how many fragments would be observed, and what would be the sizes (in bp) of these fragments? Number of fragments: , Sizes: 4. Draw the actual map of the pMBBS plasmid, following the style of the sample map shown in Figure 1. Make sure you show the following information: (1) relative locations of the RE sites; (2) size in base pairs of the segments of DNA between sites. (The map need not be drawn to scale.) ||
Molecular Techniques
Molecular techniques are methods employed in molecular biology, genetics, biochemistry, and biophysics to manipulate and analyze nucleic acids (deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)), protein, and lipids. Techniques in molecular biology are employed to investigate the molecular basis for biological activity. These techniques are used to analyze cellular properties, structures, and chemical reactions, with a focus on how certain molecules regulate cellular reactions and growth.
DNA Fingerprinting and Gel Electrophoresis
The genetic makeup of living organisms is shown by a technique known as DNA fingerprinting. The difference is the satellite region of DNA is shown by this process. Alex Jeffreys has invented the process of DNA fingerprinting in 1985. Any biological samples such as blood, hair, saliva, semen can be used for DNA fingerprinting. DNA fingerprinting is also known as DNA profiling or molecular fingerprinting.
Molecular Markers
A known DNA sequence or gene sequence is present on a chromosome, and it is associated with a specific trait or character. It is mainly used as a genetic marker of the molecular marker. The first genetic map was done in a fruit fly, using genes as the first marker. In two categories, molecular markers are classified, classical marker and a DNA marker. A molecular marker is also known as a genetic marker.
DNA Sequencing
The most important feature of DNA (deoxyribonucleic acid) molecules are nucleotide sequences and the identification of genes and their activities. This the reason why scientists have been working to determine the sequences of pieces of DNA covered under the genomic field. The primary objective of the Human Genome Project was to determine the nucleotide sequence of the entire human nuclear genome. DNA sequencing selectively eliminates the introns leading to only exome sequencing that allows proteins coding.
