161 reviews of The Second City Theatre Probably one of the coolest spots in Toronto! This place is always full of life and loud laughter, you go in not expecting much, and always impresses! The cast keeps changing every now and then along withâ¦
how do mutations give you cancer. some mutations of DNA in body cells affect genes that control cell division. describe how point mutations and frameshift mutations affect the synthesis of proteins. Point mutations change only one nucleotide in a codon, therefore only changing one amino acid in a protein. Point mutation does not affect the synthesis of proteins.
Students will evaluate how mutations in the DNA sequence may or may not affect the expression of the gene or the sequence of amino acids in the encoded protein. There are two types of mutations, small-scale gene mutations and large-scale chromosomal mutations. (base substitution) are shown below. In frameshift mutations. , an insertion or deletion of a base changes the reading frame of the sequence since mRNA is read in groups of three nitrogen bases (codons). This causes several amino acids to be affected unless the deletion or insertion is a group of three.
