Answer:
I believe that it is the lettuce.
Explanation:
it is the fist thing in the graph so it is the start/producer of the chain.
Question
Microarrays allow for
•a comparison of expression of different genes under different growth conditions.
• 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.
