A mutation within a gene that will insert a untimely cease codon in mRNA would result in a shortened polypeptide chain.
<h3>What occurs if there is a untimely end codon?</h3>
Thus, nonsense mutations occur when a premature nonsense or end codon is added in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins
<h3>What mutation motives untimely cease codon?</h3>
In genetics, a nonsense mutation is a factor mutation in a sequence of DNA that effects in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and normally nonfunctional protein product.

Answer:
Ashing process is done to evaluate the ash content present in petroleum or other proucts, so that they can be used for certain applications
The two major types of ashing process that includes dry ashing and wet ashing and can be performed using microwave systems or conventional means.
a. errors made in the preceding method while determining the ash content of buttermilk by conventional dry ashing are as following:
- Buttermilk should not immediatly put into muffle immediatley, it should be boiled first to avoid splatter.
- Temperature should be between 500 to 600 degree celcius at high temperature teh ash content can be loss.
- The sample should be ashed for 12-18 hrs
, more than this can damage the required ash content.
- platinum tip should be used in place of stainless steel because platinum has a lower concomitant tip impedance than stainless stell, so less reactive to ash.
- The ash should put in dessicator and not allow to kept in open because ash can react with the humidity in teh atmosphere.
b. The result that occur due to above errors such as the temperature, time, tongs and leaving ash in open will manipulate the final ash content and its application can be harmful for humans and for other purpose if it will be used.
I believe the correct answer from the choices listed above is option D. The sentence that best explains why the plant grows more slowly would be the <span>plant has less cholorphyll to produce energy. Since it can be found in the leaves of the plant. Hope this answers the question.</span>
Adaptions to collect and retain water - thick, non-pourous stems, not leaves, but thick lobes and the ability to store water until its needed.
Answer:
A. All of these choices are correct.
Explanation:
In pharmacology , drugs play different roles from simple to complex.
as is the above mentioned question drugs can facilitate the transmission of information from one neuron to another so option B is correct.
While the drugs / chemicals can inhibit the transmission of information from neuron to another so option C is also correct.
And the drugs can also be used to cure a whole variety of clinical disorders by playing a role at the synaptic level.
Hence option A All of these choices are correct is the right answer.
