<span>Initiation is when the RNA polymerase separates the strands of DNA at the site of the promoter and connects the RNA nucleotides while they base pair with the DNA template. Elongation is when the polymerase moves downward undoing the DNA and stretching the RNA transcript to the 3 prime end. As this occurs the strand begins to form a double helix. Termination is when the RNA transcript is released and the polymerase disconnects from the DNA.</span>

mRNA molecules are synthesized from one strand of DNA.


The mRNA strand transports the DNA information for a particular gene from the nucleus of the cell to a ribosome for protein synthesis.


Once the mRNA strand directs protein synthesis, the strand is destroyed.


The transcription of a gene is controlled by the cell.

Ringing in the ears is called:
Elza [17]

Answer:

c. tinnitus

Explanation:

Tinnitus (a hearing impairment) is a form of  hearing of sound when no external sound is present Which is often described as a Ringing,Tinnitus may also sound like a clicking or roaring. i.e usually unclear voices or music are heard. The sound may be soft or loud, low or high pitched, and appear to be coming from one or both ears. Ranging from one person to another, the sound may causes depression or anxiety and can interfere with concentration.

Otitis externa is a condition that causes inflammation , the inflammation also covers  (redness and swelling) of the external ear canal, i.e the tube between the outer ear and eardrum.

Meniere's disease popularly called (MD), is a disorder of the inner ear that is characterized by episodes of feeling like the world is spinning (vertigo), hearing loss, and a fullness in the  ear. The cause of MD involves both genetic and environmental factors. Some of the factors include constrictions in blood vessels, viral infections, and autoimmune reactions.

Otosclerosis is a condition where one or more foci of irregularly laid spongy bone replace part of normally dense enchondral layer of bony otic capsule in the bony labyrinth. This condition affects one of the ossicles (the stapes) resulting in hearing loss, vertigo or a combination of symptoms.

Therefore from the foregoing we can conclude that Tinnitus is the correct anwser.

When does cell differentiation occur? Question 1 options: when cells express the same gene when cells express different genes wh
serg [7]

Answer:

The answer is when the cell express different genes.

Explanation:

Cell differentiation is the process when a cell is changed from one cell type to an other and brings more complexity to the system. A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation. A multicellular organism undergoes several rounds of cell differentiation during its development. Although cell differentiation changes the size, shape and metabolic activity but the genetic makeup or DNA is never changed during cell differentiation.

In numerous studies, treatment of prion preparations with ionizing and UV radiation does not reduce transmission of disease; how
mel-nik [20]

Answer:

A. Prions do not contain genetic information, which is affected by ionizing radiation.

B. Denaturants may affect the tertiary structure of prions.

C. Prions are proteins.

Explanation:

Prions are the proteinaceous infectious particles that cause many degenerative diseases of neurons in both animals and humans. They consist of only protein and no DNA or RNA. Due to the absence of DNA or RNA as genetic material, these infectious particles are resistant to ionizing radiation. Ionizing radiations affect nucleic acids of pathogens to destroy them.

Denaturation of proteins affects their secondary and tertiary structures and leave them non-functional. Denaturation may be caused by changes in temperature, pH, disturbance of hydrogen bonds, etc. Therefore, to destroy prions, they need to be denatured.
