2) There are two types of stem cells: adult and embryonic stem cells.
3) Stem cells are not specific to one area in the body and can turn into skin, bone, blood or brain cells.
Answer:
G1/S checkpoint
Explanation:
G1/S checkpoint is one of the points in the cell cycle, between growth phase 1 and DNA synthesis phase, where a cell that has been damaged is sensed by DNA repair enzymes and further degraded by apoptosis. In cancer cells, there is mutation in these DNA repair enzymes and thus nothing to correct the cells from dividing even when damaged and thus there is no arrest of division and cells continue dividing
Answer: The two examples of conduction and induction are as follows.
Explanation:
Conduction can be defined as the process of transfer of charges from the charged body to the neutral body by direct contact whereas the induction is a process in which the charges are induced in the neutral body by the charge body. The conduction process requires the direct contact between the bodies in which the charges are being transmitted.
The example of the conduction process involves the neutral metal sphere gets charged when comes in contact of aluminum plate that exhibit a charge.
The example of induction is the rubbing of the rubber balloon with that of the animal fur then the two balloons will move away due to like charge repel each other.
Codon is three DNA and RNA nucleotides that go to a certain amino acid and or stop certain protein signal during synthesis
Hope this helps :)
