How do researchers prepare an intron-free copy of a eukaryotic gene for use in creating transgenic bacteria?
Tcecarenko [31]

The researchers prepare an intron-free copy of the eukaryotic gene for the use in creating the transgenic bacteria by using the reverse transcriptase to make the cDNA from the mature mRNA

The structure of the eukaryotic genes. Most of the eukaryotic genes are contain the segments of the coding sequences (exons) that interrupted by the noncoding sequences (introns). Both the exons and the introns are transcribed to yield a long and primary RNA transcript.

Eukaryotic DNA is the linear, compacted into the chromosomes by the histones, and has the telomeres at each end to protect from the deterioration. The Prokaryotes contain the circular DNA in addition to the smaller, transferable DNA plasmids. Eukaryotic cells contain the mitochondrial DNA in the addition to the nuclear DNA

Axons from mPFC neurons synapse onto intercalated cells in the amygdala that contain the neurotransmitter __________.
sammy [17]

The medial pre Frontal Cortex neurons synapting with the intercalated cells of Amygdala contains <u>GABA</u> as the neurotransmitter.

Option a

<u>Explanation:</u>

The Amygdala has two types of nerve cells getting attached with it primarily. They are the fibres from the mPFC or medial pre Frontal Cortex and the vIPAG or ventrolateral periaqueductal grey. These neurons do have different functions on the whole body.

The fibres from the mPFC do have emotional function on the human body whereas the fibres of vIPAG do have an effect on the muscle tone . And it's seen that both the nerve fibres that are getting attached with the intercalated cells of Amygdala do secrete GABA and are inhibitory GAB Anergic in nature.

Describe how the granite of a mountain could change first into sandstone and then into quartzite.
Naily [24]
Weathering causes the granite to break down into small particles - sand. The sand becomes buried and compacts into sandstone. If the sandstone continues to be buried and comes into close contact with high heat, such as magma, it can be turned into quartzite.

Which of the following are among the most common second messengers?
frosja888 [35]

Answer:

The correct answer would be calcium ion and cAMP.

Secondary messengers refers to the intracellular signaling molecules which pass the signals from the receptors located on the surface of the cell to the target molecule present within the cell.

The secondary messengers can be classified into three major class:

  1. Cyclic nucleotide for example cAMP (cyclic adenosine monophosphate), cGMP (cyclic guanosine monophosphate)
  2. DAG (diacylglycerol) and IP₃ (inositol triphosphate)
  3. Calcium ions (Ca⁺⁺)  

Hence, from the given options, calcium ion and cAMP would make the correct choice.
