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:
1.tissue
2.organ system
3.organ
4.cell
5.tissue
Explanation:
1.Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body. Many organs working together to accomplish a common purpose is called an organ system.
2.Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body. Many organs working together to accomplish a common purpose is called an organ system.
3.Cells grouped together to perform a specialized function are known as a tissue. Tissues arranged together to perform a special function are known as an organ. Organs that together to perform the many functions of the body as a whole are called a system. ... Any abnormal development of tissues or organs.
4.Molecules are the chemical building blocks of all body structures. A cell is the smallest independently functioning unit of a living organism.
