Researchers working on Alzheimers disease identify a gene which may help treat the condition., but use a shortened version of the gene ..which codes for all necessary amino acids .. can anyone explain how the shortened version may be obtained ..

If any could flag the main points I should be okay ..

Thanks :-)

To obtain a shortened version of a gene that codes for all necessary amino acids, researchers typically employ a process called gene editing or gene splicing. Here are the main points to understand:

1. Identifying the gene: Researchers first need to identify the specific gene associated with a particular trait or condition, in this case, a gene related to Alzheimer's disease.

2. DNA extraction: Once the gene is identified, DNA is isolated from cells that contain the gene of interest. This can be done using various laboratory techniques.

3. Gene splicing: The DNA sequence is then manipulated in a laboratory to remove or alter specific sections of the gene. In the case of obtaining a shortened version, certain parts of the gene may be deleted or modified.

4. Creating a shortened version: By removing or altering certain portions of the gene, researchers can create a shortened version that still codes for all necessary amino acids. Care must be taken to ensure that the resulting modified gene maintains its essential functionality.

5. Validation and testing: The shortened gene is then tested to ensure it functions as desired. This may involve various methods such as cloning the modified gene into cells and observing the resulting effects.

It is important to note that the specific techniques and tools used for gene editing can vary, and there are multiple methods available, such as CRISPR-Cas9, zinc finger nucleases, and TALENs. Each method has its own advantages and limitations.

Remember, gene editing is a complex and precise process that requires specialized knowledge and equipment.
