The mutations that is the most probable cause of beta thalassemia in a patient without a family history of the disease is A nonsynonymous point mutation resulting in a premature stop codon
<u>Explanation:</u>
The disorders that are related with blood are called Beta thalassemias. When the synthesis of the beta chains that are present in the hemoglobin blood does not happen this will be caused. The result of this will be anemia with high severity.
The existence of mutations in the gene HBB on 11th chromosome is the main reason for the Beta thalassemias. It is the mutation's characteristics that determines the disease to be either severe or not. The blocking of HBB results in the decrease of the synthesis of beta chains.
Over the last 120 years, the average temperature of the troposphere has increased by 0.5ºC.
Answer:
The gene that encodes ampicillin resistance.
Explanation:
The plasmid would contain the ampicillin resistance gene which gets expressed in the presence of ampicillin.
The pattern of disproportionate dumping of toxic waste and other forms of pollution in neighborhoods where the poor and people of color live is called Environmental Racism.
This involves the placement of low-income or minority communities in the proximity of environmentally hazardous or degraded environments, such as toxic waste, pollution and urban decay. The socially marginalized racial minority communities are subjected to disproportionate exposure of pollutants and/or the denial of access to sources of ecological benefits such as clean water, air, and natural resources.
The posttranslational alterations of proteins may include the addition of polysaccharides to proteins (Option 4).
<h3>What are posttranslational alterations of proteins?</h3>
The posttranslational alterations of proteins are different modifications in the protein sequences in order to activate their functions and or suppress them.
One of the most common posttranslational alterations of proteins is phosphorylation, which occurs at specific amino acid residues and it is able to activate or deactivate proteins in order to change the signaling pathway associated with their functions. Polysaccharides can also be added to proteins in order to change their functional states.
Therefore, with this data, we can see that the posttranslational alterations of proteins are able to modify the functional properties of a protein and polysaccharide addition in one of these types of modifications that both structural proteins and enzymes suffer to activate an or deactivate them.
