• the analysis of global gene expression.
•the hybridization of cDNA (converted from mRNA with DNA affixed to a solid-state support.
• all of the above.
Answer:
• all of the above.
Explanation:
Microarray involves the collection and isolation of genetic samples (DNA) from a sample or tissue.
Microarray is composed of a large number of DNA material that is arrange sequentially for easy identification and use.
Microarray is used to compare the expressions of various types of genes that are growing under different conditions. It can also be used for analysis of genes globally.
Answer:
i think its the energy of light
Explanation:
In alpha decay, the nucleus loses two protons. In beta decay, the nucleus either loses a proton or gains a proton. In gamma decay, no change in proton number occurs, so the atom does not become a different element. ... If it loses two protons through alpha decay, it will have 82 protons
