Only one nucleotide is removed and DNA polymerase replaces the one abnormality The error in one strand of DNA is removed as well as several nucleotides on either side of the error. The gap that was removed is filled in by DNA polymerase The entire homologous chromosome is used to repair the double stranded DNA error The affected DNA strand and its complementary strand is discarded and a new double stranded DNA is created Sex-linked dominant Autosomal Recessive Sex-linked recessive mitochondrial Lactose blocks RNA polymerase from binding the promoter sequence, facilitating transcription of the LCT gene. Lactose prevents binding of transcription factors at the transcription start site of the LCT gene. The presence of lactose causes nucleosomes to separate, exposing the LCT gene. The presence of lactose causes nucleosomes to pack together tightly, exposing the LCT gene. 256 65,536 32 64 Ionic bond Hydrogen bond Disulfide bond Hydrophobic interaction Two or more polypeptides each with their own secondary structures come together to form a single larger tertiary structure of a protein Peptide bonds between amino acids make up the secondary structure of a protein The interactions between the side chains of the amino acids make up the secondary level structure of a protein The interactions between the side chains of the amino acids make up the tertiary level structure of a protein Replacing a positively charged amino acid with a negatively charged amino acid Replacing a polar amino acid with a non polar amino acid Replacing a polar amino acid with another polar amino acid
