Answer:
A
Explanation:
Because it is way more logic
1- Preparing the cDNA:
a- Using two different tissue samples (such as control and cancer cells), isolate mRNA.
b- For each sample, prepare complementry DNA (cDNA) from the isolated mRNA. Then fluorescent label cDNA of each sample with a different color and then mixed.
2- preparing the microarray:
a- Bind DNA fragments of different genes to microarray wells.
b- Attach ssDNA (single-stranded DNA) to microarray wells.
3- Combine the probe and the microarray samples:
Add labeled cDNA to the microarray wells.
Let's take the example of touching something hot:
there's sensory nerves in all our body, including our hands and fingers. When a finger touches something hot. a nerve impulse will be born due to the stimulus and will be transmitted from the sensory nerves in the finger to the CNS (central nervous system)
The CNS will integrate the information, then transmit nerve impulses through the motor nerves which goes to the muscles of the finger (which are skeletal muscles) to order them to contract, to avoid the contact between the finger and the hot thing. (the same map for the blinking eye)
Answer:
Conclusion. Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
