Answer:

F2 Generation.

Explanation:

After Mendel collected seeds from the F1 plants, he set them to soil and waited for the F2 generation to grow from them. In the F2 generation, out of the 1064 plants, 787 were tall and 277 were dwarf. And that is roughly three quarter were tall and one quarter were dwarf, giving a ratio of approximately 3:1.

At this point, Mendel called dwarfness a recessive because it has receded in the F1 generation only to appear in the F2 generation and that of tallness was termed to be dominant in the pea crossing experiment of Mendel.

When RNA polymerase synthesizes a new mRNA, interactions between the RNA polymerase, the DNA, and the RNA hold the complex toget
timurjin [86]

When a hairpin loop forms in the nascent mRNA: The hairpin will destabilize the interaction and possibly lead to  transcriptional termination.

Transcription in prokaryotes like E. coli is terminated either by a rho-dependent process or a rho-independent process. Intrinsic termination is controlled by the specific sequences of RNA .

When the termination process starts, the transcribed mRNA forms a stable secondary structural hairpin loop, also known as a stem-loop. Several uracil nucleotides follow this RNA hairpin. The uracil and adenine connections are exceedingly weak. NusA, a protein attached to RNA polymerase, attaches to the stem-loop structure so firmly that it momentarily stalls the polymerase.

The polymerase is pausing at the same time that the poly-uracil sequence is being transcribed. The RNA-DNA duplex can unwind and separate from the RNA polymerase because the weak adenine-uracil interactions reduce the energy of destabilization for the RNA-DNA duplex. Overall, transcription is terminated by the modified RNA structure.

Which of the following is not a role of the basal nuclei?initiating protective reflex actionsinhibiting unnecessary or antagonis
Rzqust [24]

Initiating protective reflex actions  is not a role of the basal nuclei

Explanation:

A reflex is the “simplest response” to Stimulus. The two examples of reflex           are sneezing and blinking.  The main role of reflex is to produces a quick motor response.  Reflexes are “very fast” and most of reflexes not reach the brain.  Reflex can be understood as blinking of eyes from any danger.

The main role of sensory neuron is to carry impulse from receptors to the spinal cord and motor neuron carry impulses from the spinal cord to the effectors.
