What else can I help you with?
The first phase of mitosis is called?
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.
During prophase each pair of chromosomes is attached to each other by the?
During prophase, each pair of chromosomes is attached to each other by structures called homologous chromosomes. These homologous chromosomes have similar genes but could have different alleles.
What stage in meiosis do homologous chromosomes come together?
During meiosis, the homologous chromosomes come together during prophase I. Pairs of homologous chromosomes align during a process called synapsis and form a tetrad (four sister chromatids, two from each pair of homologous chromosomes). During synapsis, crossing over may occur, during which homologous chromosomes exchange genetic material.
What stage mitosis is it when chromosomes shorten and thicken and the nuclear membrane begins to disappear?
The stage of mitosis where chromosomes shorten and thicken and the nuclear membrane begins to disappear is prophase. During prophase, the chromatin condenses into distinct chromosomes and the nuclear envelope breaks down, allowing the chromosomes to interact with the spindle fibers.
At what stage in meiosis are the chromosomes visible?
Chromosomes are visible during the prophase stage of meiosis, specifically during prophase I. This is when the chromosomes condense and become visible under a microscope.
During which phase does the chromatin condense into chromosomes?
The chromosomes coil up and condense during prophase
What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
What is the DNA called during prophase?
During prophase, DNA is condensed and tightly coiled into structures called chromosomes. These chromosomes are made up of DNA and proteins and are visible under a microscope.
The first phase of mitosis is called?
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.
The phase during mitosis in which DNA separates into pairs of chromosomes is?
The phase during mitosis in which DNA separates into pairs of chromosomes is called prophase. During prophase, the chromosomes condense and become visible as distinct structures before the actual separation occurs during later stages of mitosis.
What is the phase of mitosis when chromosomes become visibly shortened and thickened?
Prophase
During prophase each pair of chromosomes is attached to each other by the?
During prophase, each pair of chromosomes is attached to each other by structures called homologous chromosomes. These homologous chromosomes have similar genes but could have different alleles.
What is the phase where chromation condenses form to chromosomes?
The cell's chromatin condenses into chromosomes during prophase. In contrast, telophase is where the chromosomes loosen to form chromatins.
Name the phase of cell division when duplicated chromosomes first appear?
The phase of cell division when duplicated chromosomes first appear is called the prophase. In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the chromosomes to be more clearly visible.
What stage in meiosis do homologous chromosomes come together?
During meiosis, the homologous chromosomes come together during prophase I. Pairs of homologous chromosomes align during a process called synapsis and form a tetrad (four sister chromatids, two from each pair of homologous chromosomes). During synapsis, crossing over may occur, during which homologous chromosomes exchange genetic material.
When homologous chromosomes swap pieces during meiosis this is called?
crossing over.
The pairing up of maternal and paternal chromosomes during meiosis happens in?
The pairing up of maternal and paternal chromosomes during meiosis happens in the prophase I stage. This pairing is called synapsis and results in the formation of a structure called a tetrad.
