Answer:
The correct answer is stem cell
Explanation:
Stem cells are the cells that can convert into any specific type of cell by dividing it repeatedly. So stem cells are unspecialized and can give rise to specialized cells.
As they can divide repeatedly and give rise to a specialized type of cell they allow the body to heal, repair and grow. There are different types of stem cell like induced pluripotent cell, adult stem cell, an embryonic stem cell.
Stem cell transplant is used to in the patient who cannot produce normal blood cell, for example, bone marrow transplant.
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made up of protein and a single molecule of deoxyribonucleic acid (DNA).
The unique structure of chromosomes keeps DNA tightly wrapped around spool- like proteins, called histones. Without this kind of packaging, DNA molecules would be too long to fit inside the cells.
DNA molecules in a single human cell if unwound from their histones and placed end to end, they would measure 6 feet in length.
Chromosomes play a key part in ensuring that DNA is accurately copied and distributed to new daughter cells as the parent cell divides to form new cells.
