Two processes that produce different proteins in different cells from the same primary transcript are RNA editing and alternative RNA splicing. These two change the protein in different cells, although all the cells have the same gene.
What is RNA modification?The gene makes the mRNA, but the primary mRNA of eukaryotes is immature because the mRNA has both the intron and the exon regions. The introns are removed by the process of splicing, but in alternate splicing, the exons change positions. This is the result of the alternation of the traits that are found in the cells.
Hence, both RNA editing and alternative RNA splicing produce different proteins in different cells from the same primary transcript.

In the video about the construction of the insect phylogeny, the researchers faced the problem that there was not enough computational power in all of the world to construct every possible tree. What was the researchers’ solution?.
So the probable solution for this problem will be Use math to avoid constructing improbable trees
Computational phylogenetics refers to the application of computer tools, techniques, and programmes to phylogenetic study. A phylogenetic tree representing a theory about the evolutionary history of a group of genes, a species, or other taxa is being constructed. To build every conceivable tree in the globe would have required more computing power than was available. The anthropomorphic or improbable trees are those in which we truly perceive human or animal forms, as if they were entrapped within the tree form. And when we do, the once-familiar tree transforms into something astonishing, unusual, unbelievable, and revered because it is the illustration of how enigmatic forces can confine live things inside wood. Trees are likened to people. They are similar to us in that they have a body (the trunk), arms (the branches), feet (the roots), a blood supply (the sap), and thinning hair (their leaves).

W ith each step during a marathon, a coordinated effort is taking place between your brain and the muscles in your body.
Place the following steps in order to describe this process for muscle contraction.
Drag the text blocks below into their
correct order.
- ATP is used to allow actin to slide past myosin, resulting in a shortening of the cell as muscle contraction occurs.
- Motor neurons carry the signal for contraction from the brain to the cells that make up each muscle.
- Neurotransmitters cross the synapse and bind to receptors on the muscle cell membrane.
- An electrical wave is triggered in the muscle cell, which triggers the release of calcium ions from the endoplasmic reticulum.
- Motor messages originate in the frontal lobe of the cerebrum and travel to the cerebellum to be refined and coordinated.
- The electrical wave causes neurotransmitters to be released into the synapse between the motor neuron and the muscle cell.
During muscle contraction, there are motor messages that originate from the frontal lobe of the cerebrum and travel to the cerebellum. Motor neurons carry signals from the brain from here to muscle cells.
An electrical wave is then generated releasing neurotransmitters such as acetylcholine into synapses between motor neurons and muscle cells. These neurotransmitters cross synapses and bind to receptors on muscle cells. This generates electrical waves in the muscle, releasing calcium ions from the endoplasmic reticulum.
After this step, calcium ions bind to troponin on actin and displace tropomyosin. At this stage, actin binds to myosin and forms crosslinks. Since myosin has an ATP binding site, ATP is hydrolyzed to release energy. This energy moves actin filaments inward to M-lines and myosin outward to Z-lines. This leads to sarcomere shortening or muscle contraction.
Hence the correct order is (starting from top 1st-6th): 2, 1, 6, 3, 4, 5.

What is a dihybrid cross?A Dihybrid cross is a cross between two individuals with two observed traits controlled by two different genes. This describes a mating experiment between two organisms that are identical hybrids for two traits. Hybrid organisms are heterozygous, meaning they have two different alleles at a particular genetic position or locus. Dihybridization was initially valuable as an experimental test of Mendelian laws, showing that each trait can be inherited independently according to Mendelian rules. It has since become an important tool for mapping genes to chromosomes and elucidating how genes can interact to determine phenotypes.
The phenotypic ratio of a dicross in a standard Mendelian experiment is 9:3:3:1. In this case, her two pairs of alleles are grouped separately into gametes.

Which component of eukaryotic cells is critical for the correct sorting and transport of proteins?.
In eukaryotic cells, the Golgi body, a component of the endomembrane system, transports and changes protein.
Proteins produced either by endoplasmic reticulum (ER) are processed in the Golgi before being sent to the cell. Proteins reach this same Golgi on the part that is trans to the ER and leave on the side that is trans to the cell's plasma membrane (trans side). Proteins must pass through a series of intermediate cisternae where they are altered and packed before being transported to various parts of the cell. Three primary cisterna are typically represented diagrammatically, however this is a simplification. The trans Golgi system (TGN) and the cis Golgi system (CGN) are occasionally inserted as extra sections on each side (TGN). These systems have a more complex structure, with some vesiculated and some cisterna-like areas.
