If a researcher looks at a cell and notices a straight line of sister chromatids, which phase are they viewing? a. interphaseb. prophasec. prometaphased. metaphasee. anaphasef. telophase

D. metaphase

Explanation:

Cell cycle comprises 2 phases (1) Inter phase & (2) Mitotic phase.

In interphase, a cell prepares itself for cell division while in mitotic phase, a cell undergo changes which result in cell division.

Mitotic phase further contains 4 main phases which are mentioned as under:

(1) Prophase

(2) Metaphase

(3) Anaphase

(4) Telophase

In metaphase particularly, all the sister chromatids get arranged along the equitorial plate in the middle of the cell so that the replicated chromatids could be separated from each other with the help of spindle fibers. After separation, each cell i.e. mother cell and daughter cell get one copy of the duplicated chromatids.

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4

~ use this opportunity to get more so you can thrive in the classroom
