what is gene mutation? It is the change in a single base pair within the DNA
what are some effects of gene mutation? some gene mutation have no effect, others result in less active products, others result in inactive products, while others are beneficial
Gamete cell mutations affect ______ affect the egg and the sperm
True or False: offsprings of an individual that has gamete cell mutation can be affected True
Point mutation happens when ____ base change in the DNA sequence one base changes in the DNA sequence
what is frame shift mutation? This is the addition or deletion of one or more bases
what is silent mutation? This is the substitution of a single base in the third base nucleotide position of a codon.
what is the result of silent mutation? There is NO change in the amino acid
what is missense mutation? This is the substitution of a single base in the first or the second base nucleotide position
Does missense mutation result in change of the amino acid? Yes, it result in a change in the amino acid
what is nonsense mutation? This is the substitution of a single base that yield a stop codon
what is frame shift mutation? This is where one or more bases are added or deleted in the DNA
what are some results of frame shift mutation? This mutation can make the DNA meaningless and often results in a shortened proteins and non functional
what are some examples of chromosome mutation? deletion, dupication, inversion, translocation
what are some examples of gene mutation? point mutation (silent, missense and nonsenses mutation) and frameshift mutation (addition, deletion mutation)
Deletion mutation is the _____ of a chromosomal segment loss of a chromosomal segment
Duplication mutation is the _____ of a chromosomal segment repetition of a chromosomal segment
what is inversion mutation? It is the change in the direction of the genetic material along a single chromosome
what is translocation mutation? This occurs when a segment of one chromosome become attached to a different chromosome
There are two types of inversion mutation _____ and ____ paracentric and pericentric inversion mutation
what is paracentric inversion? This is when the centromere is not included in the inversion
what is the pericentric inversion? This is when the centromere is involved in the inversion
