Scientists manipulate DNA in living cells to study gene function, create genetically modified organisms, develop new treatments for diseases, and enhance agricultural crops. By altering DNA sequences, scientists can understand the role of specific genes in biological processes and potentially harness these insights for various applications.
Scientists can manipulate DNA through techniques like PCR (polymerase chain reaction) to amplify specific DNA sequences, genetic engineering to introduce new genes into an organism, and gene editing tools like CRISPR-Cas9 to make precise changes in the DNA sequence. These techniques allow scientists to study genes, create genetically modified organisms, and potentially treat genetic diseases.
Bacteriophages are good cloning vectors because they can carry foreign DNA into bacterial cells, where the DNA can be replicated and studied. This allows scientists to easily manipulate and study specific genes.
A restriction enzyme is a protein that cuts DNA at specific sequences, allowing scientists to manipulate and study DNA by cutting it into smaller fragments.
Scientists can obtain DNA from various sources such as blood samples, saliva, hair roots, skin cells, and tissue samples. These samples contain cells that can be used to extract and analyze DNA. Additionally, DNA can also be obtained from organisms such as bacteria, plants, and animals for research purposes.

Yes. Bacteria are living organisms. All living organisms have DNA.
Yes. Everything that was made has DNA in their cells.
No, DNA is a molecule, a helical one. It is contained in all living cells. Even cells in animals living on the bottom of the ocean where there is no sun.

All living cells contain both RNA and DNA. RNA is involved in gene expression and protein synthesis, while DNA stores genetic information. These molecules are essential for cellular function and replication.
Not true. They both do. DNA is contained in all living cells.

One reason why scientists may use bacterial DNA over human DNA in biotechnology is because bacterial DNA is often easier and cheaper to manipulate and study given its simpler structure compared to human DNA.
