How are the accuracy of dna and mrna codes assured

Accuracy of DNA and mRNA codes are assured through proofreading and complimentary base pairing.

Explanation:

DNA replication is the process of producing two identical daughters DNA molecules from a parent DNA molecule. During the process of replication, the accuracy of the DNA is usually ensured by mean of proofreading, which is carried out by DNA polymerase enzyme. This enzyme accurately copy the genes in the parent molecule into the daughter molecules.

During the transcription stage of protein synthesis, the transcription process is proofread by RNA polymerase, which catalyzed the process of producing mRNA. During the translation process, the accuracy of the mRNA codes are ensure by mean of complimentary pairing of bases; adenine bind to uracil while guanine bind to cytosine.

its like this, "if i give a plant an unlimited amount of sunlight,then the plant will grow to its largest possible size."

hope it let me know if it does or doesn't =^-^=

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
