and then something amazing happens: recombination. Recombination (aka “crossing over”) is the process that makes prophase I so special. It’s essentially a scrambling-around of genetic material that introduces some variation into the eventual daughter cells. Recombination is one of the hallmarks of...
If mitosis makes somatic cells, what does meiosis make? How are meiosis 1 and meiosis 2 different? Explain the main difference between mitosis and meiosis. How do homologous chromosomes know to pair up? Why do all the normal cells in the human body have the same number of chromosomes?

If mitosis makes somatic cells, what does meiosis make? Does mitosis produce somatic cells or gametes? What is diploid? How many chromosomes are in a human cell? How many pairs of homologous chromosomes would be present in a cell undergoing metaphase II?
What Is Mitosis? A Complete Guide to Mitotic Cell Division If you’re studying biology, the concept ofmitosisis pretty unavoidable.Mitosis is part of the cell cycle, and studying how cells work makes up a huge portion of any biology class.It’s safe to say you’re going to need some ...
Mitosis and meiosis bothinvolve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development....
after a cell divides into 2, cell grows to mature size; cell doubles organelles & gathers materials needed for DNA synthesis. Many cells (muscle, nerve, bone) never leave G1. S: DNA replication occurs in this phase G2: cell makes proteins needed for cell division (like protein needed to...
(MHC). B cells carrying two MHC haplotypes could bridge the MHC barrier between B cells that performedThermal Cyclersnot share MHC. Thus, B cells straight relay autoreactivity between two individual compartments of MHC-restricted T cells, leading to addition of distinct B cell populations in ...
Before discussing the specifics about a particular step in the division of a cell's genetic material, it is useful to step back and review what takes place inside cells to even reach this point. DNA is one of two nucleic acids, the other being ribonucleic acid (RNA). Although DNA might...
types of cells in the body has a different lifespan. For example, red blood cells live about a month and white blood cells live more than a year, while skin cells live for only a few weeks. This makes it necessary for cells to replicate, or create replacement cells, on a regular ...
