Question

Select the correct answer. according to the video, what do scientists look for when comparing the sequence of a genome with cancer to the sequence of a normal genome?

Answer 1

Scientists compare cancerous genomes to normal genomes to find mutations and other changes that might explain cancer development and help tailor treatments.

Step-by-step explanation:

When comparing the sequence of a genome with cancer to the sequence of a normal genome, scientists look for differences between them. These differences may include mutations, changes in the number or structure of chromosomes, or alterations in the DNA sequences that structure genes and regulatory elements. By identifying these variations, researchers can better understand the genetic basis of cancer and develop targeted treatments or preventive strategies, contributing to the field of pharmacogenomics.

Answer 2

Scientists look for genetic alterations or mutations when comparing the sequence of a cancer genome to a normal genome.

Step-by-step explanation:

When comparing the sequence of a genome with cancer to the sequence of a normal genome, scientists look for specific genetic alterations or mutations that are associated with the development of cancer. These alterations can include changes in the sequence of DNA bases, such as mutations or chromosomal rearrangements. By comparing the genomic sequences of cancer and normal cells, scientists can identify these alterations and gain insights into the molecular mechanisms of cancer development.
