Which sequence of terms represents a decrease from the greatest number of structures to least number of structures present in a cell?

How many DNA molecules are in a chromosome just before mitiosis?
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.
Number of DNA molecules in a chromosomes?
Each chromosome contains a single DNA molecule that is highly compacted and coiled around proteins. This single DNA molecule contains all the genetic information for an organism.
If the chromosome number for a chimp is 48 how many monads in a somatic cell in anaphase?
In anaphase of mitosis, the chromosomes are duplicated and each pair is separated. For a chimpanzee with a diploid chromosome number of 48, there are 24 pairs of chromosomes. During anaphase, each chromosome is split into two sister chromatids, resulting in 48 monads (individual chromatids) in a somatic cell.
The chromosome number after meiosis is denoted as?
The chromosome number after meiosis is denoted as haploid, meaning that the cells have half the number of chromosomes compared to the original cell. In humans, the chromosome number after meiosis is 23.
A flask contains 0.380 mol of liquid bromine Determine the number of bromine molecules present in the flask?
The number of bromine molecules present in the flask can be calculated using Avogadro's number, which is 6.022 x 10^23 molecules/mol. In this case, there are 0.380 mol of bromine, so the number of bromine molecules present is 0.380 mol x 6.022 x 10^23 molecules/mol.
What is the figure that gives the number of identical molecules in a formula?
The subscript in a chemical formula indicates the number of identical molecules present. For example, H2O indicates two molecules of water present.
What Maintains the chromosome number in the daughter nuclei?
During cell division, a structure called the mitotic spindle separates the duplicated chromosomes and ensures that each daughter cell receives the correct number of chromosomes. Additionally, checkpoints in the cell cycle regulate the progression of mitosis to ensure that the chromosomes are apportioned correctly and the daughter cells have the proper chromosome number.
How many molecules are present in 936 g of glucose?
To find the number of molecules present in 936 g of glucose, you would first calculate the number of moles of glucose using its molecular weight. Then, you would use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
Which sequence of terms represents a decrease from the greatest number of structures to the least number present in a cell?
gene,chromosome THEN nucleus :) HOPE YOU DO WELL !!
What does avogadro's number tell you?
It gives the number of atoms or molecules of a substance which will be present in one mole.
When are the sister chromatids of each duplicated chromosomes separated?
The sister chromatids of each duplicated chromosome are separated during cell division in a process called anaphase. This occurs in both mitosis, which results in two identical daughter cells, and meiosis, which produces gametes with half the chromosome number.
