What else can I help you with?
Are chromosomes now visible during prophase?
In prophase there's just the condensation of the chromatin material into chromosomes...& nuclear membrane disappears but the chromosomes aren't clearly visible,they are better visible during metaphase..!
Is iit true or false that our sex cells have the same amount of dna in as your heart cells?
That is false. All body cells, including heart muscle cells have 46 chromosomes. Sex cells have 23 chromosomes.
What kind of cell involves chromosomes?
Eukaryotic cells, which make up plants, animals, and fungi, have chromosomes within their nucleus that contain genetic information in the form of DNA. Prokaryotic cells, such as bacteria, do not have a true nucleus or chromosomes.
Why do chromosomes become more visible during prophase?
During prophase, chromosomes condense and become more visible because they coil tightly to form shorter and thicker structures. This condensation helps prevent tangling and facilitates the movement of chromosomes during cell division. Additionally, the condensation of chromosomes helps ensure that each daughter cell will receive the correct number and type of chromosomes.
What is made of DNA and is the storage area for all genetic information?
Chromosomes are where DNA is found. These are found in many cells in what we call the nucleus. Other cells don't have a true nucleus but they do have chromosomes.
Is this true that sex Cells have one-half of the number of chromosome Pairs as body -Somatic- Cells have?
Yes, that is true. Sex cells, such as eggs and sperm, are haploid, meaning they have half the number of chromosomes as somatic cells. Somatic cells are diploid, with two sets of chromosomes inherited from both parents.
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.
Do All cells within an organism will have the same number of chromosomes except the gamete?
Yes, all cells within an organism (excluding gametes) typically have the same number of chromosomes, known as the diploid number. This number is characteristic of the species and remains constant throughout most of the organism's cells. Gametes, such as sperm and eggs, have half the number of chromosomes (haploid) to ensure the correct chromosome count is restored upon fertilization.
True or false reassortment of chromosomes can occur during meiosis by crossing over or by independent segregation of homologous chromosomes?
True. Reassortment of chromosomes can occur during meiosis through both crossing over (where chromatids exchange genetic material) and the independent segregation of homologous chromosomes (where chromosomes separate randomly into daughter cells).
Are there more chromosomes than genes in skin cells?
Yes. That's true for any cell type
Mitosis is one type of cell division that produces identical copies f the cell?
That's correct. Mitosis is a process in which a cell duplicates its chromosomes and divides into two identical daughter cells. It is essential for growth, repair, and maintaining the number of chromosomes in the cells.
True or false human sperm and egg cells have 23 chromosomes?
True. Sperm and egg cells are gametes, and thus are necessarily haploid. These haploid gametes were created through the process of meiosis. When the two fuse to create an embryo, the new embryo will then have 46 chromosomes, the full number for a human. The embryo will receive one copy of each chromosome from each parent. If sperm and egg cells were to have the full set of 46 chromosomes, with both copies of each chromosome from each parent, then when they fused the embryo would have 92 chromosomes total. And the progeny of that embryo would have an even higher number of chromosomes. Having haploid gametes is necessary to maintain the stability of the species.
