stage of the cell cycle where ribosome and organelles increase in number
The cell cycle, also known as the cell-division cycle, is the sequence of events that occurs in a cell that causes it to divide into two daughter cells. Hence, the correct answer is 'G2 phase'.
What happens in G2 phase of cell cycle?
The cell expands more during the second gap phase, also known as the G 2 start subscript, 2, end subscript phase, and begins to restructure its contents in preparation for mitosis.
What is cell cycle briefly explain stages?
The cell cycle is a four-stage process during which the cell grows (gap 1, or G1), copies its DNA (synthesis, or S), prepares to divide (gap 2, or G2), and divides. Interphase is made up of the stages G1, S, and G2, and it accounts for the time between cell divisions.

What are the three 3 types of chronological order?
The three types of chronological orders are: Chronological, Sequential, and Consecutive.
Chronological order is the one where things are arranged one after the other in the sequence in which they occurred. It is considered to be the easiest pattern in orders. Chronological order is considered similar to going down the stairs.
Sequential order is the type of order in which things are arranged according to numbers or alphabets. It is the step-by-step directions of any event or situation from the first step to the last one. It is different from chronological order as chronological order is more concerned with time.

what happens to the cftr gene in cystic fibrosis
A buildup of sticky mucus results from mutation in the CFTR gene that impair or prevent the production of the CFTR protein, which in turn causes recurrent lung infections, pancreatic damage, and difficulties in other organs.
A recessive illness is one such as cystic fibrosis. About 70% of individuals with CF have the most prevalent CFTR mutation, F508del. This mutation results from of the loss of three dna bases from the CFTR gene, which causes the CFTR protein to lose the amino acid phenylalanine, also known as amino acid F. F508del, the most prevalent CF mutation, is generally thought to be a reprocessing mutation. The CFTR protein loses one amino acid due to the F508del mutation. The CFTR protein could maintain the right 3-D structure without this component. The heterogeneous multiorgan illness known as cystic fibrosis (CF) is brought on by mutations inside the CFTR gene that result in the misfolding (and other abnormalities) and subsequent malfunction of the CFTR protein.

A stem cell is a cell from which new cells with specialized functions are formed. Stem cells divide by
mitosis to produce new cells that serve one of two purposes. One purpose is self-renewal. Through this
process, stem cells divide and create more stem cells. The other purpose is differentiation. This occurs
when a stem cell divides and one daughter cell retains stem cell properties while the other creates a
specialized cell such as a heart cell, skin cell, or brain cell.

What is the correct order of events in mitosis ?
Prophase, Metaphase, Anaphase, & Telophase are the proper phases of Mitosis.
A single cell divides into 2 daughter cells during the mitotic process. Two main processes make up mitosis: cytokinesis, or cytoplasm division, and karyokinesis, or nucleus duplication.
The separation of the daughter cells comes next. Prophase, Mitotic phase, Anaphase, & Telophase are the four phases of Karyokinesis.
Prophase: During prophase, chromosomes may be seen, centrioles can move to the poles, the nucleolus and nuclear membrane disappear, and spindle configuration takes place. Chromosomes align completely around the center during metaphase. Chromatids separate during anaphase and go to the opposing poles through spindle fibers. This makes it possible for every daughter cell to possess a replica of each chromosome from the mother cell. Chromosomes disappear during the telophase, during which the nuclear membrane repairs, nucleoli resurface, the spindle disappears, and centrioles divide.To know more about mitosis at

Where is pure protease digested?
The central location where proteases digest proteins is in the small intestine. The pancreas releases numerous proteases as zymogens into the duodenum.
The pancreas releases proteases into the proximal small intestine, where they combine with proteins that gastric secretions have already altered and convert them into amino acids, the building blocks of protein, which are then absorbed and utilized by the body. Proteases can be obtained from microbial, plant, or animal sources. Chymotrypsin, pepsin, renin, and pancreatic trypsin are examples of animal proteases. Enterokinase is secreted from the top small intestinal epithelium in response to meals, and this enzyme catalyzes the protease cascade in the small intestine. Pancreatic pro-proteases are transformed into active enzymes by the enzyme catalyzer enterokinase.
