What is the name for the area in which these duplicated strands joined?

What is the name for the area in which these duplicated strands are joined? Duplicated strands of chromosomal DNA are called chromatids, or sister chromatids, and they are joined by a centromere.

During what phase of the cell cycle is the DNA duplicated?

In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase).

What structures are spindle fibers attached to that help pull the paired chromosomes apart?

What structures are spindle fibers attached to that help pull the paired chromosomes apart? The spindle fibers are attached to centrioles that move toward the poles of the cell, pulling the chromatids apart.

What is the name for the spot at my waist where the two chromosomes are joined?

genetics. …of two identical replicas, called chromatids, joined at a point called the centromere.

What are two chromatids together called?

Sister chromatids

A sister chromatid is either one of the two chromatids of the same chromosome joined together by a common centromere. A pair of sister chromatids is called a dyad.

What is DNA replication called?

DNA replication is called semiconservative because an existing DNA strand is used to create a new strand.

How is DNA replicated in a cell?

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. ... Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands.

What structure produces spindle fibers?

Spindle fibers are produced in the centrosome from cylindrical microtubules called centrioles.

Which is the name of the circular strand of DNA found in the prokaryotic cell?

Prokaryotes generally have a single circular chromosome that occupies a region of the cytoplasm called a nucleoid. They also may contain small rings of double-stranded extra-chromosomal DNA called plasmids.

When the genetic material of a cell is loose and stringy it is called?

What is a chromatin? Stringy form of DNA with loose association to proteins. It is the typical state of genetic materials in the nucleus.

Where are centromeres located?

The centromere is a very specific part of the chromosome. When you look at the chromosomes, there's a part that is not always right in the middle, but it's somewhere between one-third and two-thirds of the way down the chromosome. It's called the centromere.

What's the difference between kinetochore and centromere?

The key difference between centromere and kinetochore is that centromere is the region of the chromosome that holds two sister chromatids together after the replication of chromosome while kinetochore is the disc-shaped protein complex of the chromosome that allows spindle fibers to attach during the cell division.

What is interphase mitosis?

Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.

What do you call the duplicated chromosome?

The two identical chromosomes that result from DNA replication are referred to as sister chromatids. Sister chromatids are held together by proteins at a region of the chromosome called the centromere.

What are the two halves of a duplicated chromosome called?

A chromatid is one of two identical halves of a replicated chromosome. During cell division, the chromosomes first replicate so that each daughter cell receives a complete set of chromosomes.

Why are chromosomes replicated?

DNA replication is an essential part of both mitosis and meiosis. It ensures that each daughter cell has the correct number of chromosomes. To replicate the DNA in mitosis, each chromosome replicates so that the new chromosome is attached to the original one at the centromere.

Squirrels lose excess heat to shaded surfaces and camels to cooler night air. A variety of adaptation examples can be seen in desert biome animals. .....
