An amino acid can be formed by combining 3 nucleobases. In the test, the only nucleobase the mRNA is uracil. That means the possible combination of the nucleobase should be only UUU. Since there is only 1 possible combination, there should be 1 possible amino acid that can be formed.
<span>Phenylalanine should have UUU codon.</span>
<span>The answer to this question is the second option-" carbohydrate polymers formed as water is removed". In the dehydration synthesis, polymers are created. This is when two molecules formed a new product which results the loss of water. So, this is a process of forming or making a new compound together with the removal of water.</span>
According to DNA methylated bases, the cell alteration linked to differential cytosine methylation on disease patients' DNA is referred to as an epigenetic modification.
<h3>What do you understand by epigenetics?</h3>
The study of epigenetics, a branch of genetics that focuses on how various chemical alterations to the DNA nucleotide sequence and associated chromatin proteins (histones) may change the expression of particular genes, is crucial for understanding disease states and developmental pathways.
The epigenetic changes, which control gene expression in specialized eukaryotic cells, include DNA methylation organized on CpG islets (cytosine-rich areas), acetylation and/or methylation of histones, non-coding RNA pathways, etc.
The study of how chemical groups added to DNA and/or associated chromatin proteins may change gene expression and hence affect the status and progression of disease is known as epigenetics, according to the findings presented here.
