The two different colors indicate that one chromosome came from the father and one chromosome came from the mother. Duplicate chromosomes are formed through the process of DNA replication, which occurs before mitosis begins.
What is the difference between the red and blue chromosome?
The blue chromosome gets split in half correctly so that each identical sister chromatid ends up in the final, divided cell. The red chromosome, on the other hand, does not split like it should.
What colors are present inside the cell on the chromosomes?
DNA can be wound around proteins and create large visible structures in the nucleus called chromosomes. Color the chromosomes dark green. The interior of the cell is made of a fluid called cytoplasm. Embedded in the cytoskeleton are microtubules that help the cell maintain its shape and form.
Why are the chromosomes colored red and blue in this figure what does red or blue represent?
Answers to questions about the mitosis figure: The two daughter cells are the same as each other, and same as the parental cell. Each rod represents a chromatid, and DNA replication results in two sister chromatids joined at their centromeres. … Red and blue are chromosomes inherited from the male and female parents.
What does N mean in mitosis?
If a haploid cell has n chromosomes, a diploid cell has 2n (n represents a number, which is different for every species – in humans, for example, n = 23 and 2n = 46). … Therefore, if a diploid cell undergoes mitosis, the result is two identical diploid cells (2n →2n).
Is chromatin made of DNA?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Each nucleosome is composed of DNA wrapped around eight proteins called histones. …
What can happen if cells do not duplicate correctly?
The cell cycle controls the four major phases of cell growth and division. … If the cell has not properly copied its chromosomes, an enzyme called cyclin dependent kinase, or CDK, will not activate the cyclin, and the cell cycle will not proceed to the next phase. The cell will undergo cell death.
Do chromosomes have color?
Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). … Scientists gave this name to chromosomes because they are cell structures, or bodies, that are strongly stained by some colorful dyes used in research.
Is DNA unique to each person?
Although each organism’s DNA is unique, all DNA is composed of the same nitrogen-based molecules. So how does DNA differ from organism to organism? It is simply the order in which these smaller molecules are arranged that differs among individuals.
