How do the structure and location of a prokaryotic chromosomes differ from that of a eukaryotic chromosome?
because they do
How does a duplicated chromosome differ from a chromatid?
Chromosomes are what make up your genetic material. During interphase when the chromosomes are duplicating, they remain attached to their duplicated with a centromere. When they are connected with their duplicate, each individual of this pair is called a chromatid. So a duplicated chromosome is made up of two chromatids which are identical to each other.
How do cells of people with Down syndrome differ from those of others?
They have an extra chromosome 21.
How does mitosis differ from meiosis in terms of chromosome segregation?
In mitosis, chromosomes are duplicated and then segregated into two identical daughter cells, resulting in cells with the same number of chromosomes as the parent cell. In meiosis, chromosomes are duplicated but then segregated twice, resulting in four daughter cells with half the number of chromosomes as the parent cell.
How does a pair of sister chromosome differ from a single unduplicated chromosome?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
How does a single pair of sister chromatids differ from a single unduplicated chromozone?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
How do boys chromosomes differ from girls?
Boys have one x chromosome and a y chromosome, whereas a girl has two x chromosomes.
How do X and Y chromosome differ?
The X chromosome is larger and carries more genetic information than the Y chromosome. The Y chromosome carries the genes that determine male sex characteristics, while the X chromosome carries genes that are important for both male and female development. Males typically have one X and one Y chromosome, while females have two X chromosomes.
How does the chromosome number in a diploid cell differ from the chromosome number in a haploid cell?
A diploid cell contains two sets of chromosomes, one from each parent, while a haploid cell contains only one set of chromosomes. In humans, a diploid cell has 46 chromosomes (23 pairs), whereas a haploid cell has 23 chromosomes.
How do the cells of people with down syndrom differ from those of others?
People with Down syndrome have an extra copy of chromosome 21 in their cells, leading to 47 chromosomes instead of the usual 46. This genetic condition can result in various physical and cognitive differences, such as distinctive facial features and intellectual disabilities, compared to individuals without Down syndrome.
How does diplonema differ from diakinesis?
Diakinesis is the last stage of prophase during meiosis. Diplonema is the doubled form of the chromosome strand during the diplotene stage of meiosis.
What is the agent that causes male genitals to differ from female genitals prior to birth?
The presence or absence of the Y chromosome is the key factor that determines whether a fetus will develop male or female genitals. The Y chromosome triggers the production of testosterone in male fetuses, leading to the development of male genitalia. In the absence of the Y chromosome, female genitalia develop by default.
