What happens to genes when cells divide?
If a cell divides by mitosis both cells will have the diploid (2N) number of chromosomes. These two cells will have identical DNA If a cell divides by meiosis subsequent cells will have the haploid (1N) number of chromosomes. These cells will have the same basic amount of DNA but the DNA will not be identical. If the sex chromosomes are different sizes (like the X and Y chromosomes of humans) the DNA will vary a bit more dramatically if the meiosis includes the additional variation of the different sex chromosomes.
The chromosomes of eukaryotic cells have more what than do the chromosomes of prokaryotic cells?
The chromosomes of eukaryotic cells have more DNA than the chromosomes of prokaryotic cells. Prokaryotes usually only have 1 circular chromosome and no "junk DNA", while eukaryotes are multi-chromosomal.
Which types of mutation affects more genes a gene mutation or a chromosomal?
a gene is passed on from generations and a chromosome is just found in certain cells
Sex-linked genes are usually found in which chromosome?
Sex linked genes are located on the sex chromosomes.
Which is more complex chromosome or gene?
Chromosome is more complex than gene. Chromosomes contain multiple genes along with other regulatory elements, while genes are specific sequences of DNA that encode for proteins or RNA molecules. Chromosomes also play a role in organizing and packaging genes within the cell nucleus.
What describes the relationship between the number of genes and the number of chromosomes in human skin cells?
There are more genes than chromosomes in skin cells.
The chromosomes of eukaryotic cells have more?
genes
Are there more chromosomes than genes in skin cells?
Yes. That's true for any cell type
How many cells do haploid cells have?
Genes vary but there are 23 chromosome pairs in a haploid cell in humans. 22 are autosomes (chromosomes other than sex chromosomes) and 1 pair of sex chromosomes. There are thousands or more genes in just a section of DNA so I can't answer that. Hopefully that helps.
What does chronic myeloid leukemia affect?
Chronic Myeloid Leukemia affects genes in the blood cells. Abnormal chromosomes develop and create new genes, these genes allow diseased blood cells to survive. You can learn more about Chronic Myeloid Leukemia at the Mayo Clinic website.

Do chromosomes have the same or different genes?
There are many more genes than chromosomes. The Human Genome Project currently has identified about 20,000 protein-coding genes, while there are only 46 chromosomes in the human genome.
Are there more chromosome than genes?
No. Humans have 46 chromosomes " beaded " with about 25,000 genes.
Are like the words that make up the books of instructions called chromosomes?
Chromosomes are structures within cells that contain our genetic information in the form of DNA. They are not like individual words in a book, but rather more comparable to the entire book itself. Each chromosome contains many genes, which are like individual instructions that help determine our traits.
Is the sperm cell Eukaryotic or Prokaryotic cell?
The word prokaryote is interchangeable with the word bacteria. Because sperm cells are not bacteria, it is not a prokaryote, but a eukaryote. In a more complex answer, you cannot make prokaryote from a eukaryote, because sperm cells are made from a eukaryotic cell. That's like saying that your fig tree grows peanuts.
What are two ways that sex cells differ from other cells?
Chromosomes are basically our DNA combined with structural protein. Sex cells contain chromosomes. Chromosomes are packaged genetic information while sex cells are the means by which people reproduce.
The chromosomes of eukaryotic cells have more what than do the chromosomes of prokaryotic cells?
The chromosomes of eukaryotic cells have more DNA than the chromosomes of prokaryotic cells. Prokaryotes usually only have 1 circular chromosome and no "junk DNA", while eukaryotes are multi-chromosomal.
