During mitosis, cells replicate all their contents, including chromosomes, and divide to form two identical daughter cells.
<h3>What is Mitosis?</h3>
Mitosis is the process by which one cell divides into her two identical daughter cells (cell division).
- During mitosis, the cell divides once to form two identical cells.
- The main purpose of mitosis is to grow and replace worn-out cells.
- Mistakes made during mitosis, if not corrected in time, can lead to DNA changes that can potentially lead to genetic diseases.
Mitosis is divided into following phases:
- Interphase
- Prophase
- Metaphase
- Anaphase
- Telophase

Answer:
Polypeptide
Explanation:
Amino acids are the building block and simplest unit of protein molecules. The structural composition of each amino acids is made up of an amine group (-NH2), a carboxylic acid group (-COOH), a hydrogen atom (H) and a R side chain that differentiates every amino acid from one another.
In a reaction process called condensation, amino acids are chemically joined together via the amine group of one and the carboxylic group of another. This process releases water molecule (H20) to form a bond called PEPTIDE bond between the amino acids. Several amino acids in their 100’s or 1000’s that are chemically joined this way forms a POLYPEPTIDE chain, which in turn forms the protein molecule.
Answer: Option B.
Explanation:
The first experiment of the passage shows that treatment with TGFBR1 and TGFBR2 antagonists led to lower levels of epithelial cell production. For this conclusion to be strongly valid, we want to show a positive correlation between TGFBR activity and epithelial proliferation.
Well it couldnt be an animal cell becuase animal cells dont have cell walls. And plant cells have a cell membrane not a plasma membrane so it should be a prokaryotic cell.
