An alteration in the nucleotide sequence of a gene can alter the gene product. each sentence below is made up of three-letter words, representing mrna codons. the red ant ran the fox was red the dog ran the same sentences are written below with a substitution, deletion, or insertion, much as a gene may have a substitution, deletion, or insertion mutation. identify which sentence represents a substitution, which represents a deletion, and which represents an insertion.

→completion of the questions: which represents  substitution , deletion and insertion. THE DGR AN THE  RED ANA TRAN THE FOX  WTS RED,

DGR from DOG (O substituted with G);SUBSTITUTION

AN from ANT (T deleted from ANT)DELETION

ANA from ANT( A substituted T in ANT) SUBSTITUTION

TRAN from RAN(T inserted before RAN) INSERTION

WTS  T substituted  A in WAS   SUBSTITUTION

Explanation:

deletion , substitution and insertion are different  pattern,of  genetic mutations  Gene substitution   is  not  as severe as the insertion, and deletion; because the two give a different  protein combination compare to the  normal protein sequence, by  causing A FRAME SHIFTS   which affect the next CODONS,
