| Descriptor in English: | DNA Sequence, Unstable |
| Descriptor in Spanish: | Secuencia de ADN Inestable |
| Descriptor in Portuguese: | Sequência de DNA Instável |
| Descriptor in French: | Séquence instable d'ADN |
| Entry term(s): |
DNA Sequences, Unstable Sequence, Unstable DNA Sequences, Unstable DNA Unstable DNA Sequence Unstable DNA Sequences |
| Tree number(s): |
G05.360.340.024.189 |
| Scope note: | A region of DNA that is highly polymorphic and is prone to strand breaks, rearrangements or other MUTATIONS because of the nature of its sequence. These regions often harbor palindromic, or repetitive sequences (REPETITIVE SEQUENCES, NUCLEIC ACID). Variability in stability of the DNA sequence is seen at CHROMOSOME FRAGILE SITES. |
| Allowable Qualifiers: |
