Answer:

B. Nucleosomes

Explanation:

Chromatin is made up of certain repeating units called nucleosomes. Each nucleosome has a stretch of DNA that is wound around a complex of eight histone molecules. The eight histone molecules together make histone octamer. A DNA of 146 base pairs is wrapped around this scaffold made up of histone molecules.

A stretch of DNA called linker DNA joins the adjacent nucleosomes together. The DNA wound around the histone scaffold appears as a beadlike structure. One nucleosome scaffold has two copies of each of four different histone types. These are called H2A, H2B, H3, and H4. Histone H1 is joined to the linker DNA.

As in most areas of biology, the study of mitosis and the cell cycle involves a lot of new terminology. Knowing what the differe
puteri [66]

1. DNA replication produces two identical DNA molecules, called sister chromatids, which separate during mitosis.

2. After chromosomes condense, the centromeres is the region where the identical DNA molecules are most tightly attached to each other.

3. During mitosis, microtubules attach to chromosomes at the Kinetochores.

4. In dividing cells, most of the cell's growth occurs during Interphase

5. The mitotic spindle is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division.

6. During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed form called ,chromatin.

7. In most eukaryotes, division of the nucleus is followed by cytokinesis, when the rest of the cell divides.

8. The centrosomes are the organizing centers for microtubules involved in separating chromosomes during mitosis.

Which of the following is not a type of asexual reproduction?
insens350 [35]

Answer:

Fertilization

Explanation:

Binary fission is when single parent cell doubles it’s DNA, then divides into two cells. (usually in bacteria).

Budding is the small growth on surface of parent breaks off, resulting in formation of two individuals. (ex: yeast)

Fragmentation is when organisms break into two or more fragments that develop into a new individual. (occurs in many plants and some animals like starfish)
