Why is it important for DNA to condense before dividing?
DNA condensation is used to block the transcription and translation of a number of genes. It is part of "epigenetics" by condensation of the DNA the polymerase can no longer bind.
Why is it important for the chomosome to make copies of themselves BEFORE mitosis occurs?
It is important for chromosomes to make copies of themselves before mitosis to ensure that each daughter cell receives a complete set of genetic information. The copied chromosomes, known as sister chromatids, are then separated during mitosis to ensure equal distribution of genetic material to the two daughter cells. This process helps maintain genetic stability and prevents loss of important genetic information.
Why were the scientists not able to observe most of the cell organelles before 1940?
Before 1940, scientists were limited in their ability to observe most cell organelles due to the lack of advanced microscopy techniques. Light microscopes, which were primarily used at the time, could not resolve structures smaller than about 200 nanometers, making it difficult to see many organelles. The development of electron microscopy in the 1940s allowed researchers to visualize cellular components at much higher resolutions, revealing the complex structures of organelles that were previously unseen.
When do chromosome duplicate themselves during mitosis?
Chromosomes duplicate during the S phase of interphase, which occurs before mitosis. Each chromosome replicates to form two identical sister chromatids that are held together at the centromere. These sister chromatids are then separated and pulled to opposite poles of the cell during mitosis.
Are cell vesicles in all cells?
Yes, all cells have vesicles. Vesicles are what the proteins and nutrients get put in before they are sent out to different organelles.
How do chromosomes duplicate before dividing in meiosis?
During meiosis, chromosomes duplicate through a process called DNA replication. This involves the separation of the two strands of the DNA molecule and the synthesis of new complementary strands. This results in two identical copies of each chromosome, known as sister chromatids, which are then separated during cell division.
Why is it important for a cell to copy its hereditary information before dividing?
Copying its hereditary information before dividing ensures that each resulting cell receives a complete set of genetic instructions. This is essential for maintaining genetic continuity and passing accurate genetic information to the next generation. It helps prevent errors and ensures proper functioning of the new cells.
What was used to duplicate materials before photocopiers?
Carbon paper was widely used.
When are chromosome duplicate before or during mitosis?
Chromosomes are duplicated before mitisis in S phase of inter phase .
Why is it important that DNA is duplicated before cell division?
It is essential that the DNA is duplicated before cell division, because without it, the new cell would not be able to function, nor duplicate again. The copy of DNA is placed in the new cell essential for survival.
What do you do before dividing by a decimal?
Move the decimal point
How do you duplicate Weapons on Dead Island?
Throw the weapon you want to duplicate,then,before said weapon hits the ground, go to the inventory and drop the weapon you threw,so you have the one you threw and dropped.
What do chromosomes do before dividing in mitosis?
They double into more chromosomes.
Why would you estimate before dividing a decimal?
Because you can get the wrong answer
How many chromosomes does a human cell have before dividing?
46

Which organelles is responsible for sorting proteins before they are sent to the body of the organims?
Golgi apparatus
