Bacteria can be used to produce human growth hormone (HGH-a peptide/protein) through genetic engineering. The human gene for HGH is inserted into a plasmid, which is then taken up by a bacterial cell, which divides and multiplies into a clone of cells, all of which contain the plasmid with the HGH gene. The bacteria express the HGH gene, producing HGH which can be harvested and used for treatment of humans. (See figure below) Which of the following statements is NOT true about this process? DNA pla bacterium PO Bo Ⓒ Ⓒ None of the other four answers (All are true statements) The bacterium taking up the plasmid DNA is an example of transduction Once the HGH gene has been inserted into the plasmid, this is an example of a cloning vector O Expression of a human gene by a bacterial cell is possible because the genetic code in mRNA is the same for all organisms Because HGH is a peptide (protein), the bacterial cell can make it by transcribing the HGH gene and translating mRNA on bacterial ribosomes
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.
