Copy number changes is considered as genetic changes which does not lead to the formation of oncogenes.
Copy number change- The cytogenetic level of resolution, known as copy number variation (CNV), involves both duplications and deletions of sequences that generally have lengths between 1,000 base pairs and 5 megabases.
Genetic Change- Genetic mutations, which occur as our cells divide and generate duplicates of themselves, are modifications to your DNA sequence.
Base Pairs- The DNA molecule is made up of two bases (or nucleotides) that contain nitrogen. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four bases of DNA (T). These bases come in certain pairings (A with T, and G with C).
