What do chromosomes carry | DNA |
where are chromosomes and DNA located | the nucleus |
what happens when DNA divides | coils and condenses into chromosomes |
why do cells divide | when an organism grows and when an organism becomes damaged |
what is the cell cycle in order | cell growth, DNA synthesis, further growth, mitosis, cytoplasm separates into 2 different cells |
what occurs in mitosis | a parent cell divides into two daughter cells |
how do we find how long a part of the cell cycle is | number of cells in that stage/ total number of cells |
what is a stem cell? | cells that have not gone through differentiation |
what happens to cells removed from the embryo | they can differentiate into any kind of cell type |
what are adult stem cells | stem cells that remain in the bodies of children and adults |
name 3 regions of the body stem cells are found in | brain, blood and liver |
what can stem cells divide into | different cell types |
What the potential risks and benefits of stem cell transplantation as a treatment for conditions | Immunity reactions, infections and accesibility |
How do embryonic stem cells differ from adult stem cells in terms of their ability to differentiate? | embryonic stem cells have a higher differentiation potential |
What are the two main sources of adult stem cells for transplants | Patient's own stem cells, Donor stem cells |
What is therapeutic cloning, and how does it differ from other forms of cloning? | transferring the nucleus of a patient's cell into an egg cell whose nucleus has been removed, creating a cloned embryo. |
what are the ethical downside to embryonic stem cells | they could stop potential life from being made |
