Document Summary
Which of the following is possible due to the semi conservative replication of dna: repair before replication, correction after replication, both, none. Point mutations, insertions, and deletions also occur in non-coding dna. Mutation in regulatory sequences can alter gene expression. Errors in base pairing detected during dna replication. Polymerase removes last nucleotide, backs-up, and then continues synthesis. Repairs changes in nucleotides caused by dna damage. Detects distortions in double helix from incorrect base pairing: detect error, detect methylated template, excision, fill in, ligation. Genetics deals with traits encoded by genes (genotype->phenotype) Genomics studies how genes are organized, how they work together, and the impact of non- coding dna on the phenotype. The total genome is all genetic material in an organism, including: Often, however, genome is used in reference to nuclear genome. Genome sizes vary over several orders of magnitude. Multiple versions of closely related proteins in the same genome.
