Answer: After completing three rounds, there will be 8 segments with 2 original strands on different segments.
Explanation:
The polymerase chain reaction (PCR) processes the double-stranded DNA (dsDNA) in a PCR machine in a specific, repeated manner.
1st round:
A single unit of double-stranded DNA (dsDNA) separates into two strands, allowing complementary nucleotides to be synthesized to create a double helix.
2nd round:
The two strands of dsDNA produce 4 segments prior to the synthesis of complementary nucleotides.
3rd round:
The four dsDNA strands lead to the creation of 8 segments before synthesis again happens.
Thus, at the conclusion of three rounds, the two original strands will appear across 8 different segments of replicated DNA.
Answer:
100 units
Explanation:
The parent cell holds 200 units of DNA. During the process of cell division, this amount is distributed between the resulting daughter cells, with each cell obtaining half of the DNA present in the original cell.
As mitosis yields two daughter cells, each one will receive 100 units of DNA.
It is correct <span>that alterations in membrane permeability or ion concentration can affect the resting membrane potential. The resting membrane potential is defined by the voltage across the membrane of a neuron at rest. This potential is influenced by the concentration gradients of ions such as Na+ and K+ and by how permeable the membrane is to these ions. In a resting neuron, there exist concentration gradients for Na+ and K+ ions across the membrane. Ions traverse their gradients through channels, which results in a charge separation that establishes the resting potential.</span>
Recently, researchers have identified an enzyme, BACE2, which reduces these abnormal protein segments in the brains of Alzheimer's patients.
Respuesta:
D
Explicación:
Para que las células se dividan, deben replicar su ADNy los orgánulos, y para que las nuevas células sean del mismo tamaño que las demás, también deben crecer.
