Ok I got you let me figure it out and imma send it
Question:
The complete question has these options:
A) tRNA with anticodons is carrying amino acids to the ribosomes.
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Answer:
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Explanation:
During transcription, RNA polymerase uses DNA as a template to create a new molecule of mRNA via complementary base pairing
A) tRNA with anticodons is carrying amino acids to the ribosomes. - this is not evidence of transcription but is instead evidence of translation
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules. - this is false, DNA polymerase is the enzyme that performs DNA replication not transcription.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins - this is not evidence of transcription but is instead evidence of translation
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production - this accurately describes the process of transcription.
does it ask what are they doing moving part sliding anything like that?
Answer:
The correct answers are: Synaptic Active Zones, Exocytosis.
Explanation:
- An impulse after travelling along the dendrites, cell body and axon of a neuron reaches the axon endings in the form of an action potential (signal transmitted by the activation of voltage gated sodium and potassium channels present on the plasma membrane of the neurons).
- At the axon ending or the pre-synaptic region, the action potential triggers the opening of the voltage dependent calcium channels, that promotes the influx of calcium ions into the pre-synaptic region of the neuron.
- This process triggers the fusion of the neuro-transmitter carrying vesicles with the plasma membrane in the pre-synaptic region of the neuron.
- As a result of fusion the neurotransmitter is released into the synaptic cleft.
- At the pre-synaptic region of the neuron, there is a huge concentration of neuro-transmitter carrying vesicles which remain adhered to proteins called CAZ (cytomatrix at the active zone) proteins. These proteins help the neurotransmitter carrying vesicles to remain tethered or docked to the pre-synaptic membrane in the axon terminal of the neuron. They together form the Synaptic Active Zone.
- In response to calcium ion influx these proteins help the neurotransmitter carrying vesicles to fuse with the plasma membrane in the pre-synaptic region of the neural axon and release the neurotransmitter into the synaptic cleft.
- The process of fusion of the neurotransmitter carrying vesicles with the plasma membrane in the pre-synaptic region of the neural axon followed by the release of the neurotransmitter into the synaptic cleft is known as Exocytosis.
The complementary strand on the RNA would be, U-G-G-C-U-C-G-A-A.
