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.
Answer:
Cells are the basic building blocks of living things. Cells provide structure for the body, take in nutrients from food and carry out important functions. Cells group together to form tissues, which in turn group together to form organs, such as the heart and brain. balls:D
Explanation:
true, because it is called rotation on google
Answer:
D) found in a limited time span
Explanation:
Index fossils are the remains of living organisms for which we have already established relative age. These are fossils that only existed during a limited period of geologic time and are easily identified, found in large volumes, and found in many different locations around Earth. Due to these factors, index fossils may be used as a guide for comparison in determining the relative age of an unknown object.
have a nice day and mark me brainliest! :)
