Answer:
Histone acetylation or DNA methylation.
Explanation:
The epigenetics may be defined as the genetic phenomena that might cause mutation in the organism's genome. The DNA sequence of the organisms do not get changed in epigenetics.
This phenomena is limited whether the gene is herited from the mother ot the father. The phenomena like acetylation of histones increase the gene expression. The DNA methylation and histone deacetylation at specific residues reduces the gene expression.
Thus, the answer is histone acetylation or DNA methylation.
Answer:
B.) Anaphase II
Explanation:
In metaphase II, the chromosomes line up individually along the metaphase plate. <u>In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.</u> In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.
Answer:
gross anatomy, an anatomical region
Explanation:
Anatomy can be grouped into gross anatomy and superficial anatomy. Gross anatomy is the study of structures that are visible to the human eye i.e. without the aid of a microscope. The anatomical regions are those regions in the body that are easily seen by the unaided eye.
In this case, Luna is trying to study the name and locations of the lumbar, or lower back, area of the body. The lumbar is the vertebrae found at the lower back of the body. Hence, it is an easily visible internal structure when dissected, making it's study a form of GROSS ANATOMY.
Answer:
Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function.
