Answer:
e. Gain of function mutation in the p53 gene.
Explanation:
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Also, transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
In this scenario, you are reading a science fiction novel about a biotechnologically advanced society where individuals must choose a type of mutations for a future child to have in all its cells before they are born. As an expert biologist who wants a healthy child, you should choose a gain of function mutation in the p53 gene for your future child because they are clinically and biologically distinct.
Answer: The complimentary strand will read ATG CCC GTC GTA TTT TAG
Explanation:
The complimentary strand to the replicating DNA molecule is known as messenger RNA (mRNA).
The mRNA directs specific bases to pair the existing base on the replicating DNA strand:
- Adenine (A) pairs only with Thymine (T)
- Guanine (G) pairs only with Cytosine (C)
So, to obtain the complimentary strand of TAC GGG CAG CAT AAA ATC, substitute each letter with its base pair.
Thus, the complimentary strand will read ATG CCC GTC GTA TTT TAG
Oparin-Haldane hypothesis. The Oparin-Haldane hypothesis is named after the two scientists; <span>Russian scientist Aleksandr Oparin and English scientist J. B. S. Haldane. The two scientists separately hypothesized that life began when some inorganic molecules were converted into organic molecules specifically amino acids by the help of energy came from a lightning struck.</span>
Complete question:
The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K
Answer:
TRUE
Explanation:
The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.
Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.
Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.
K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.
Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.
