4. The forward primer used in this experiment incorporates part of the HaeIII recognition site, GGCC. How is this different from the sequence of the human TAS2R38 gene? What characteristic of the PCR reaction allows the primer sequence to "override" the natural gene sequence? Draw a diagram to support your contention. The HaeIII recognition site is GGCC, and the forward primer used in the experiment incorporating part of this recognition site means that the primer sequence has a region similar to GGCC. In the context of the human TAS2R38 gene, the natural gene sequence may not perfectly match the primer sequence. The characteristic of the PCR reaction that allows the primer sequence to "override" the natural gene sequence is the ability of DNA polymerase to extend from the primers during DNA amplification. During PCR, the DNA polymerase enzyme synthesizes a new DNA strand using the template DNA and the primers as starting points. If the primer sequence is similar to the target gene's sequence, the polymerase will initiate synthesis at the primer and extend along the template. This allows for selective amplification of the region between the primers. In this case, even if the natural gene sequence does not perfectly match the primer sequence, the DNA polymerase can still initiate synthesis at the primer's binding site and extend along the target gene. This ability of the primer to bind to a region with partial similarity and initiate DNA synthesis is a key feature of PCR.
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.
