Where do the mitotic spindle microtubules attach to the chromosomes

Answered By: Peter Rogers Date: created: Sep 09 2022

The spindle microtubules attached to the kinetochore and the MTOC shorten and pull on the chromosome, which is pulled by the sister chromatids of each chromosome, which have granules called kinetochores that are located somewhere near the centromere.

In which stage microtubules of spindle attach to chromosomes

Answered By: Andrew Gray Date: created: Nov 04 2021

So, “Metaphase II” is the right response.

In what stage of meiosis does the microtubules are attached to centromeres

Answered By: Cameron Perry Date: created: Nov 04 2021

The sister chromatids line up at the equator, or center, of the cell, which is also referred to as the metaphase plate, during which spindle fibers attach to the centromere of each pair of sister chromatids (see Figure below).Mar 5, 2021

What are the microtubules that attach to the centromeres made of

Answered By: Juan White Date: created: Aug 15 2022

Microtubules are made up of just one type of globular protein called tubulin, as opposed to the diverse fibrous proteins that make up intermediate filaments.

Asked By: Evan Campbell Date: created: Apr 11 2022

What is the protein structure where your microtubules attach called

Answered By: Gilbert Murphy Date: created: Apr 12 2022

Some of the microtubules attach the poles to the chromosomes by connecting to protein complexes known as kinetochores, while others extend from the centrioles in all directions to form what is known as a spindle.

Asked By: Neil Campbell Date: created: May 11 2022

What is the name of the attachment point between sister chromatids in a chromosome

Answered By: Blake Phillips Date: created: May 14 2022

Centromeres are the attachment sites for microtubules, which are in charge of directing the movement of chromosomes during mitosis and meiosis, and they hold the two chromatids of a duplicated chromosome together (see figure below).

Asked By: Hugh Russell Date: created: Jan 21 2022

What holds the two sister chromatids together

Answered By: Malcolm Powell Date: created: Jan 24 2022

Cohesin, a tripartite complex that forms ring structures to hold sister chromatids together in mitosis and meiosis, is essential for sister chromatid cohesion.

Asked By: Ian Coleman Date: created: Mar 29 2022

What holds together 2 chromatids

Answered By: Robert Taylor Date: created: Mar 30 2022

The centromere is the point of attachment of the kinetochore, a structure to which the microtubules of the mitotic spindle become anchored, and it is this structure that holds together the two chromatids (the daughter strands of a replicated chromosome).

Asked By: Geoffrey Hill Date: created: Aug 27 2021

What usually occurs during the G1 phase

Answered By: Ashton Young Date: created: Aug 28 2021

This cellular monitoring occurs during the G1 phase, when the cell examines its surroundings and size to make sure that they are suitable for supporting DNA replication. The cell does not exit G1 until it is prepared to do so.

Asked By: Daniel Harris Date: created: May 30 2022

What do microtubules do in meiosis

Answered By: Sean Butler Date: created: May 31 2022

Microtubules attach to kinetochores so that the sister chromatids are pulled apart in mitotic cells and during meiosis II, whereas during meiosis I, they attach so that the homologous chromosomes are pulled apart.

Asked By: Norman Walker Date: created: Nov 28 2021

What anchors the spindle

Answered By: Bruce Moore Date: created: Dec 01 2021

The chromosomes center contains a protein complex called the kinetochore that the spindle fibers will bind to during mitosis. The kinetochore acts as an anchor, allowing the spindle fibers to retract and separate the sister chromatids.

Asked By: Luke Coleman Date: created: Sep 12 2022

What does the metaphase do

Answered By: Caleb Jones Date: created: Sep 14 2022

Metaphase is a phase of cell division (mitosis or meiosis) when the cells chromosomes condense and move toward one another, aligning in the center of the dividing cell. Normally, individual chromosomes are spread out in the nucleus of the cell.

Asked By: Gerld Richardson Date: created: Feb 24 2022

What is the role of centrioles

Answered By: Zachary Rogers Date: created: Feb 24 2022

Animal cell centrioles are paired barrel-shaped organelles that are situated close to the nuclear envelope in the cytoplasm. Centrioles organize the microtubules that make up the cells skeletal system and help to pinpoint the location of the nucleus and other organelles.

Asked By: Alejandro Torres Date: created: Oct 10 2021

During which phase of mitosis do the chromosomes align in the center of the cell

Answered By: Seth Adams Date: created: Oct 13 2021

The chromosomes, known as sister chromatids, which have been replicated and remain joined at a central point called the centromere, align themselves in the middle of the cell during metaphase through a type of cellular “tug of war.”

Asked By: Samuel Peterson Date: created: Jan 25 2022

Where is the mitotic spindle located

Answered By: Adrian Morris Date: created: Jan 25 2022

The dividing cells mitotic spindle, which surrounds the dividing chromosomes, is formed from centrioles during the prophase phase of mitosis.

Asked By: Alex Miller Date: created: Jun 12 2022

Which microtubules attach to the chromosome during metaphase

Answered By: Dominic Wright Date: created: Jun 13 2022

Kinetochores Attach Chromosomes to the Mitotic Spindle

  • Kinetochore microtubules, Figure 18-16.
  • The kinetochores capture of microtubules is shown in Figure 18-17.
  • Chromosomes at a mitotic spindles metaphase plate are shown in Figure 18-18.
  • Kinetochore, shown in Figures 18–19.

Asked By: Bernard Evans Date: created: Sep 25 2021

What structures are joined at a centromere

Answered By: Adrian Miller Date: created: Sep 28 2021

The centromere is the point of attachment of the kinetochore, a structure to which the microtubules of the mitotic spindle become anchored, and it is a structure in a chromosome that holds together the two chromatids (the daughter strands of a replicated chromosome).

Asked By: Douglas Bennett Date: created: Mar 14 2022

What happens in G1 phase

Answered By: Bernard Garcia Date: created: Mar 16 2022

The cell first experiences physical growth in the G1 phase, increasing the volume of both protein and organelles. Next, the cell copies its DNA to create two sister chromatids and replicates its nucleosomes in the S phase. Finally, the cell experiences additional growth and cellular organization in the G2 phase.
