sister chromatids are introduced during the (S) or synthesis phase of cell division. The two sister chromatids are separated from each other into two different cells... O <--> O
during mitosis or during the second division of meiosis.
So no, they are apart of a phase, but aren't the entirety of cell division.
I think the correct answer would be the first and the third option. The metabolic defects that are associated with stone formation are hyperparathyroidism and hyperthyroidism. Stone formation are caused by the crystallization of minerals that are not absorbed by the body properly usually it consists of calcium compounds. Both hyperparathyriodism and hyperthyriodism would cause the malabsorption of these minerals which is eventually would be linked to the formation of the stones.
Answer:
The correct answer is - inactivity of genes.
Explanation:
DNA methylation is a process in which the DNA molecule is attached to the methyl groups. Methylation affects the activity of the segment of DNA without modifying or changing the sequence of the gene.
If methylation takes place within the promoter region of the gene, DNA acts as a represser for the process of gene transcription. Inactivity of the gene is by the help of methylation in the eukaryotes is to control the gene expression.
Thus, the correct answer is - inactivity of genes.
Answer:
1. To provide energy for living organisms to perform all the other necessary functions to maintain life. Using this process in order to break down food into usable energy (ATP energy) , so that living organisms that utilizes this survives and thrives.
