What is one rod of condensed chromatin called?
Q. What is one half or one rod of the condensed chromatin called? DNA. chromatin.
What is a double rod of DNA called?
Chromatin in the nucleus condenses to form double-rod structures called chromosomes. Looks like an “X”. Each chromosome has two rods because the cell’s DNA has replicated, and each rod in a chromosome is an exact copy of the other.
What is it called when chromatin condenses?
During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.
During which phase does the chromatin condense into double rod structures?
prophase
In animal cells (mostly), a double pair of short, rod-like structures called centrioles, appear, separate and begin to move to opposite sides of the cell, outside the vanishing nucleus. mid-prophase – the chromatin threads are now condensed enough to be distinguished as individual chromosomes.
What is the condensed form of DNA?
chromatin
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus.
What are the two sides of a chromosome called?
Chromatid A chromatid is one of two identical halves of a replicated chromosome.
What is a condensed or compact rod of DNA that carries genetic information?
A double rod of condensed chromatin; contains DNA that carries genetic information. Nitrogen base that only pairs with Guanine when found in DNA and RNA. DNA. Deoxyribonucleic acid; the genetic material that carries information about an organism creates proteins and is passed from parent to offspring.
What metaphase means?
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell.
Is DNA condensed during replication?
During interphase, the cell’s DNA is not condensed and is loosely distributed. A stain for heterochromatin (which indicates the position of chromosomes) shows this broad distribution of chromatin in a mouse cell (upper left). The same stain also shows the organized, aligned structure of the chromosomes during mitosis.
What phases is DNA condensed in?
Chromosomes are most compacted (condensed) when lining up in metaphase and dividing in telophase to keep DNA molecules intact.
