Answer:
<u>Pro:</u>
May hold answers to cure various diseases including Alzheimer's and Parkinson's - these may be answers to various diseases that are not able to cure.
Requires a small number of cells because of the fast replication rate - these are able to produce a high amount of cells in the lab as they are able to replicate faster.
Medical benefits such as regenerating organ tissue and therapeutic cell cloning
<u>cons:</u>
ethical controversy over use of stem cells from lab fertilized human egg - there is an ethical controversy around the use of lab fertilized human egg
unproven treatments often come with high rejection rates - these researches provide uncertain results and not tested and easily affected so the rate of rejection is high
The cost can be prohibited for many patients - these require high cost and can not be in the budget of every patient.
Answer: is seen below
Explanation:
Termination will not take place if the strings of A nucleotides following an inverted repeat of rho- independent termination ( which forms an hairpin structure)were deleted. Although, RNA polymerase may pause briefly at the hairpin, the presence of A- U base pairs is needed to destabilize the DNA - RNA interaction and to end transcription. If the string A nucleotides is not present, then transcription of RNA polymerase will continue.
Answer:
A. If errors are not removed from areas with a gene, then the resulting proteins could be affected.
Explanation:
Since the genes in DNA contain instructions for the synthesis of proteins, any mistakes in areas of a gene will change how proteins are made.
It is important for cells to perform checks in order to catch these mistakes, because otherwise, RNA will be carrying the wrong instructions to create a protein.
