Question

From constructing mice with large deletions of gene deserts, researchers were able to conclude that gene deserts function in _______.

1) Gene regulation
2) Protein synthesis
3) DNA replication
4) Cell division

Answer 1

Gene deserts function in gene regulation. They are noncoding DNA regions that play a significant role in controlling the expression of genes, ensuring proteins are produced at appropriate times.

Step-by-step explanation:

From constructing mice with large deletions of gene deserts, researchers were able to conclude that gene deserts function in gene regulation. Gene deserts are long stretches of DNA that do not contain any genes and were once thought to be 'junk DNA'. However, these studies have shown that they play a crucial role in the regulation of gene expression, helping determine when and how much of a protein is produced by a cell.

The regulation of gene expression is essential for cell function, ensuring that proteins are synthesized at the right time and place. Gene deserts may have regulatory sequences that help control this process. Malfunctions in gene regulation can lead to diseases like cancer, underscoring the importance of these areas of the genome.
