-Started in 1990 -Scientists tried to discover the entire Human DNA Sequence.
A mutation that changes a single nucleotide, but does not change the amino acid created.
changes in genetic code
change in chromosomes
change occurs at one point in the gene. A base are switched with another base, A instead of C
Mutation in which a single base is replaced, potentially altering the gene product. Only one amino acid affected.
When a base is inserted into sequence or deleted from sequence. Since the gene is read in 3s this causes shift in the reading frame-the entire gene following the mutation is read incorrectly.
mutation in DNA sequence in which a nucleotide is added (causes a shift in reading frame).
deletion (gene level)
mutation in DNA in which a nucleotide is removed (causs a shift in reading frame).
mutation that occurs at the chromosomal level resulting in changes in the gene distribution to gametes during meiosis; caused when parts of chromosomes break off or rejoin incorrectly-can interfere with many different genes.
mutation in which extra parts of a chromosome are produced and repeated.
mutation in whick parts of a chromosome are reversed.
the movement of a segment of DNA from one chromosome to another, which results in a change in the position of the segment.
