During what phase do the chromosomes line up in the middle of the cell

Biology
1 answer:
devlian [24]4 years ago
5 0

Answer:

This phase is referred to as metaphase.

Explanation:

Initially, as the chromosomes line up in the middle, they are still connected to the centrioles via fibers. During the four phases -- prophase, metaphase, anaphase, and telophase -- the cell and genetic material begins to split evenly so that each new cell has the same genetic information.

In eukaryotes, there are two main types of DNA organization present in chromosomes:
kupik [55]

Answer:

The two main types of DNA organization present in chromosomes are the extended DNI and the condensed DNI

Explanation:

In eukaryotes, the complete chromosome is composed of only one lineal and extremely long DNA molecule. DNA is intimately associated with two types of proteins: <u><em>histones</em></u>, which are structural proteins, and <em>non-histone</em> proteins that mediate different functions of DNA.

DNA associated with histones is called <u><em>chromatin</em></u>. Histones are responsible for packaging DNA molecule, and the fundamental unit of packaging is known as a <em><u>nucleosome</u></em>. As chromatin must be condensed, nucleosomes generate regular structures between themselves forming a <em><u>chromatinic fiber</u></em>, in which DNA is very condensed. A superior level of condensation is the structural <em><u>ringlet-shaped domain</u></em>. At this level, a chromatinic fiber is folded and a protein is responsible for keeping joined the two regions of DNA that form the ringlet. The next condensation level is the rolling of the ringlet-shaped domain composing the <u><em>chromosome</em></u>. The typical chromosome in the metaphase is formed by <u><em>two chromatids</em></u> joined by a centromere. Each chromatid is composed of a sequence of chromatin ringlets domains. In the interphase, <em>before cellular division</em>, chromatin is in a diffuse, lax, uncondensed state, known as extended DNA. When <em>cellular division</em> is about to happen, chromatin begins to condensate. At the beginning of the <em>prophase</em>, DNA is condensed in a well-defined chromosome formed by two sisters chromatids.

The cornea, a boundary between the air and the aqueous humor, has a 3.0 cm focal length when acting alone
Yuliya22 [10]
If the cornea were to work alone, the image formed would be blurred as the point of image formation would be behind the retina. Therefore, with the help of the lens in the eye, the focal length is reduced to 1.7 cm so that the image forms on the retina.
