DNA molecules that shorten and thicken during cell division are known as chromosomes. Each chromosome consists of tightly coiled DNA and proteins, allowing the genetic material to be efficiently organized and separated during cell division. In humans, for example, there are 46 chromosomes in each somatic cell, which ensure proper distribution of genetic information to the daughter cells.

What stage centrioles separate?
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.
When do chromatin threads appear as chromosomes?
Chromatin threads appear as chromosomes during cell division when the chromatin condenses and coils to form distinct, visible structures that can be easily identified under a microscope. This usually occurs during the metaphase stage of mitosis or meiosis.
What type of molecules that give instructions during cell division?
The molecules that give instructions during cell division are primarily proteins called cyclins and cyclin-dependent kinases (CDKs). These molecules regulate the progression of the cell cycle by activating specific processes at different stages of cell division. Cyclins and CDKs form complexes that drive the cell through each phase of the cell cycle.
What are the fibers that shorten and pull the chromatids apart called?
The fibers that shorten and pull the chromatids apart are called microtubules. During cell division, microtubules form the spindle apparatus and attach to the chromosomes to facilitate their separation.
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 stage centrioles separate?
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.

During which phase do the chromatin fibers condense and shorten into chromosomes that are visible under the microscope?
The chromatin fibers condense and shorten into visible chromosomes during the prophase stage of mitosis. This condensation allows for easier segregation of genetic material into daughter cells during cell division.
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.
Does your tongue thicken during kissing?
no

What is the name for a hammering tool used to shorten and thicken rivets?
upset -------------------------------------------------------------------------------- Upsetting the rivet is to compress the rivet during the installation process. That can be done with a rivet gun to "hammer" the rivet against a bucking bar, or to use a rivet squeezer to compress the rivet.
Does wine thicken sauces when added during cooking?
Yes it does
Many organelles and molecules needed for cell division are formed after DNA replication and before mitosis In which phase are they formed?
The organelles and molecules needed for cell division are formed during the G2 phase of the cell cycle, after DNA replication has occurred during the S phase. This is a crucial preparation phase for mitosis, where the cell ensures it has all the necessary components for successful division.
What are the fibers that shorten and pull the chromatids apart called?
The fibers that shorten and pull the chromatids apart are called microtubules. During cell division, microtubules form the spindle apparatus and attach to the chromosomes to facilitate their separation.

Do rr intervals shorten during intervals?
what the heck is that
