In a eukaryotic cell, processing a primary mRNA transcript does not typically include changing common nucleotides into modified bases like inosine and pseudouridine. So, option B is correct.
The process by which the initial transcript from a gene acquires its mature form is collectively referred to as "RNA processing." During this process, long poly(A) sequence is attached to the 3' end and one or more guanine nucleotides are methylated at the 5' end. Also, introns are removed and exons are joined during RNA splicing.
But the conversion of normal bases to inosine and pseudouridine is not RNA processing. A natural purine nucleoside called inosine is frequently found in the anticodon loop of various tRNAs. It is created through the breakdown of adenosine. By influencing mRNA processing, translation, or stability, they can determine how mRNAs function. The nucleoside uridine has an isomer called pseudouridine. They play a role in mRNA decoding, ribosome assembly, processing, and translation while stabilizing the local structure.
The complete question is -
Processing of a primary mRNA transcript in a eukaryotic cell does NOT normally involve:
A) attachment of a long poly(A) sequence at the 3' end.
B) conversion of normal bases to modified bases, such as inosine and pseudouridine.
C) excision of intervening sequences (introns).
D) joining of exons.
E) methylation of one or more guanine nucleotides at the 5' end.

Answer:
Activities cause environmental pollution is AIR POLLUTION
Can avoid by:
•Conserve energy at home at work,everywhere.
•Use public transportation or walk whenever possible.
•Keep car, boat and other engines properly tuned.
•Mulch or compost leaves and yard waste.
•Consider using gas logs instead of wood.
The activities that cause environmental pollution in my locality are the excessive usage of vehicles that emits a huge amount of carbon, excessive utilization of polythenes, and no proper method of waste treatment.
What is Environmental pollution?Environmental pollution may be defined as any sort of unwanted contamination or impurities present in the atmosphere that is harmful and toxic to the health of each and every living organism. It is one of the most threatening problems for the whole world that affects the overall diversity of living entities and ecosystems.
You can avoid all the activities listed above by following mechanisms:

A deleterious recessive allele is one that can be harmful when it is found in its homgous condition, resulting in a poorly fit phenotype. An example of this is the allelefor sickle cell, which results in the condition known as sickle cell anemia when both recessive alleles are inherited. owever, in regions of Afriche proportion of the sickle cell allele is igher than expected, with as much as 15% of the alleles in the population being the recessive, deleteriou rsion. In the African population, there is also a high prevalence of malaria, a disease caused by the parasitic infestation of a plasmodium protozoan in the blood of humans. The recessive allele for sickle cell has been maintained over many generations. Evaluate the graph above and select the claim that supports the high frequency of the recessive allele in these African populations.
A)There is a selective advantage to the aa genotype, as the presence of sickle cell provides a greater fitness in an environment where malaria is common.
B)There is a selective pressure against the aa genotype, but the presence of malaria induces new mutations which generates more alleles within the population.
C)There is directional selection towards the Aa genotype, since aa is often a lethal condition. Non-random mating tends to maintain the recessive allele in the population.
D)There is a selective advantage to the heterozygous (Aa) condition as there is selective pressure against both the AA and aa genotypes. This maintains the recessive allele in the population.
Answer:
D) There is a selective advantage to the heterozygous (Aa) condition as there is selective pressure against both the AA and aa genotypes. This maintains the recessive allele in the population.
Explanation:
Since the AA condition is more likely to be affected by malaria and the aa condition is more likely to not survive the sickle cell condition, the heterozygote here has the advantage.
The high frequency should be considered the D) There is a selective advantage to the heterozygous (Aa) condition.
Evaluation of the graph;Since the AA condition should be impacted by the malaria and the aa condition should not able to survive the cell condition i.e. sickle.
At the same time, the heterozygote has the advantage.
Also, there is the selective pressure that oppose to the AA and aa genetypes.

If a DNA strand contains 12% thymine, it also contains ____
a. 12% A, 38% G, 38% C
b. 12% A, 12% G, 38% C
c. 12% A, 12% G, 12% C
d. 38% A, 12% G, 38% C
Answer:
If G = 14, then C = 14 and G + C is 28. Thus A + T. The percent of adenine in a double-stranded DNA is 38. Therefore G + C = 100 - 76 = 24, and C = 24/2 = 12 percent.

Find the edge length of the cube. (The density of copper is 8.96 g/cm3, and the volume of a cube is equal to the edge length cubed.)
Express your answer with the appropriate units.
Answer:
[tex]x = 2.13\ cm[/tex]
Explanation:
See comment for complete question
Given
[tex]Mass = 87.2g[/tex]
[tex]Density = 8.96gcm^{-3[/tex]
Required
Calculate the edge length of the cube
First, we need to calculate the volume of the cube using:
[tex]Density = \frac{Mass}{Volume}[/tex]
Make Volume the subject:
[tex]Volume= \frac{Mass}{Density }[/tex]
Substitute values for Mass and Density
[tex]Volume= \frac{87.2g}{8.96gcm^{-3}}[/tex]
[tex]Volume= \frac{87.2cm^3}{8.96}[/tex]
[tex]Volume= 9.73cm^3[/tex]
Represent the edge length with x.
So:
[tex]Volume = x^3[/tex]
Substitute x^3 for Volume in [tex]Volume= 9.73cm^3[/tex]
[tex]x^3 = 9.73cm^3[/tex]
Take cube root of both sides
[tex]x = \sqrt[3]{9.73cm^3}[/tex]
[tex]x = 2.13\ cm[/tex] --- approximated
Hence, the edge length is 2.13cm

Using compaction and cementation explain why sedimentary rocks are not just a loose pile of sand and rocks.
Compaction and Cementation They are compacted, reducing the available pore space and expelling much of the pore-water. Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.
Through compaction and cementation, minerals form a crusts on the sedimentary rocks which are no longer just a loose pile of sand and rocks.
What are sedimentary rocks?Sedimentary rocks are formed from the pre-existing rocks or pieces of or fossils of living organisms. They form from the deposits which accumulate on the surface of Earth. Sedimentary rocks often have distinctive layering or bedding over Earth.
Dissolved minerals present in the ground water precipitates from the water surface present in the pore spaces forming mineral crusts on the sedimentary grains, which gradually undergo cementing the sediments, which thus lead to formation of a rock.
