What describes the DNA of cancer cells?
Select all that apply.
A) Often single stranded instead of double stranded
B) Often contains mutations that affect DNA polymerase genes
C)Often contains more than one different mutation
D)Often contains mutations that affect genes involved in the cell cycle
I am hella late my fault...
But the answer is C and D
Thanks
Well, if cancer cells could talk, they would say "I'm a DNA-rebel!" So let's see which descriptions suit their wild nature:
A) Often single stranded instead of double stranded - Nope, cancer cells still like to have a double-stranded DNA party.
B) Often contains mutations that affect DNA polymerase genes - Absolutely! Cancer cells are known for their funky mutations in DNA polymerase genes.
C) Often contains more than one different mutation - Oh yes, variety is the spice of life, even for cancer cells. Multiple mutations are their thing.
D) Often contains mutations that affect genes involved in the cell cycle - Absolutely! Cancer cells have their own sense of rhythm and love to mess with the genes involved in the cell cycle.
So, the correct answers are B, C, and D. Keep an eye on those mischievous cancer cells and their DNA shenanigans!
The correct options that describe the DNA of cancer cells are:
B) Often contains mutations that affect DNA polymerase genes
C) Often contains more than one different mutation
D) Often contains mutations that affect genes involved in the cell cycle
To determine which options describe the DNA of cancer cells, we need to understand some basics about cancer cell biology.
Cancer cells are characterized by their uncontrolled growth and division, which is caused by genetic mutations that disrupt the normal regulation of the cell cycle. These mutations can occur in various genes involved in DNA replication, repair, and cell cycle control.
Now let's analyze each option:
A) Often single stranded instead of double stranded: This option does not describe the DNA of cancer cells. DNA is typically double stranded in both normal and cancerous cells.
B) Often contains mutations that affect DNA polymerase genes: This option accurately describes cancer cells' DNA. Mutations in DNA polymerase genes can lead to errors in DNA replication and contribute to genetic instability in cancer cells.
C) Often contains more than one different mutation: This option is also correct. Cancer cells often accumulate multiple genetic mutations over time, leading to increased genomic instability and heterogeneity.
D) Often contains mutations that affect genes involved in the cell cycle: This option is true as well. Mutations in genes responsible for regulating the cell cycle, such as tumor suppressor genes or oncogenes, can disrupt the normal control mechanisms and contribute to the uncontrolled growth of cancer cells.
Therefore, the correct options are B), C), and D) - often contains mutations that affect DNA polymerase genes, often contains more than one different mutation, and often contains mutations that affect genes involved in the cell cycle.
