Bio Term proofread is Literally to read for the purpose of detecting errors for later correction. DNA polymerase has 3 to 5 exonuclease activity which is used during polymerization to remove nucleotides it has recently added if they are incorrectly paired, and is a correcting ability to remove errors in replication.
Bio Term Dominant is The phenotype that is observed when two alleles of a gene are present in a cell. The gene whose phenotype is expressed is the dominant allele and the allele whose phenotype is masked is the recessive allele. If the phenotype of the diploid is inte rmediate between that of the two haploid genes, then the alleles are co-dominant.
