Questions & Step-by-Step Solutions
What is a key advantage of using yeast artificial chromosomes (YACs) as cloning vectors?
Step 1: Understand what a cloning vector is. A cloning vector is a tool used to insert and replicate DNA in a host organism.
Step 2: Learn about yeast artificial chromosomes (YACs). YACs are a type of cloning vector that is derived from yeast cells.
Step 3: Recognize the size of DNA fragments YACs can clone. YACs can clone very large pieces of DNA, often up to 1 million base pairs.
Step 4: Identify why cloning large DNA fragments is important. Cloning large fragments allows scientists to study entire genes or genomic regions, which is crucial for understanding complex traits and diseases.
Step 5: Conclude that the key advantage of YACs is their ability to clone large DNA fragments, making them valuable for genomic research.
