What is wrong with a bacterial cell if it cannot make protein

Biology

There are a variety of points in the transcriptional chain at which it is possible to disrupt protein synthesis in bacteria. Let’s enumerate just a few:

<span>There’s the initial point where DNA is transcribed into mRNA;<span>there’s the point where mRNA binds to the Ribosome complex;</span>there’s the point where tRNA-aminoacyl pair binds to the Ribosome according to the current codon being “read out” in the mRNA;there’s the point where the aminoacid transported by the tRNA is transferred to the growing protein chain; andthere’s the point where the protein synthesis is determined complete, and the Ribosome disengages and releases the newly-synthesized peptide chain.</span>

In each of these stages (and in some other, more subtle phases) there are possible points of disruption and there are specific disruptors; some of which are indicated in the aboveProtein synthesis inhibitor article.

Note, by the way, that the Ribosomes of Prokaryotes (bacteria) and Eukaryotes (cells with nuclei) aren’t identical, and therefore the inhibitors/disruptors that work for one type of cell may not (and usually don’t) work on the other type. That’s why we can take antibiotics targeted at bacteria with little to no fear of them interfering with our eukaryotic cells’ functions.

(This is a simplified, somewhat hand-wavy response. There is a lot more to say, mainly because biological systems are anything but simple. Nevertheless this should be enough to get you started in the general direction.)

The front of the white paper packet of the OSL dosimeters
Nitella [24]

Answer:

Option a

Explanation:

The front of the white paper packet of the OSL dosimeters may be color-coded to facilitate correct usage and placement of the badge on the body of occupationally exposed personnel.

OSL dosimeters are recently developed and are of high quality than thermoluminescent dosimeters.  It is used to monitor patients health status. Furthermore, it is very sensitive to any change or drop in reading. it give accurate readings even at 1 mrem for both gamma ray photos and X-rays.

A student is given a list of traits and is asked to organize them in a Venn diagram as shown below.
mart [117]

Answer: The correct answer is option B) a scar and wolf's social status.

The acquired traits can be defined as the traits, which are only influenced by the environment of the organism. The acquired trait cannot be passed down to the offspring, as they are not genetically determined. A scar and the social status of any organism is dependent on the behavior of the organism to the environment, no genes code for both of these characters. So, scars and Wolf's social status is an acquired trait.

Q 16.1: The cerebral cortex is required for A : subconscious detection of environmental changes B : conscious interpretation of
dedylja [7]

Answer:

Conscious interpretation of sensations.

Explanation:

Cerebral cortex consists of the outer layer of the cerebrum present in the brain of the humans. Longitudinal fissure divides the cerebral cortex into the right and left cerebral hemisphere.

The cerebral cortex is involved in the senses information. The conscious interpretation of the sensation is required in the cerebral cortex and contains large number of sensory innervation.

Thus, the correct answer is option (B).

1.) How do hurricanes form?
dalvyx [7]

Answer:

1.  there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.

2. Hurricanes are classified using the Saffir-Simpson Hurricane Wind Scale — a 1 to 5 rating that's based on maximum sustained wind speed, according to the National Hurricane Center.

3. When a hurricane strikes a coastal area, it brings a number of serious hazards. These hazards include heavy rains, high winds, a storm surge, and even tornadoes. Storm surge pushes seawater on shore during a hurricane, flooding towns near the coast. Heavy rains cause flooding in inland places as well.
