Question

post test: heredity
the changed nucleotide sequences to the mutations that cause them.
cattcacaca cattcacaccacg cattt cacacg cattcacg
cattgcacac
type of mutation original nucleotide sequence changed nucleotide sequence
deletion cattcacacg
insertion cattcacacg
inversion cattcacacg
duplication cattcacacg
substitution cattcacacg

Explanation:

1. Deletion: A nucleotide is removed from the original sequence. Compare original CATTCACACG to CATTCACG — the two middle "A" nucleotides are deleted.
2. Insertion: A nucleotide is added to the original sequence. Compare original CATTCACACG to CATTT CACACG — an extra "T" is inserted after the third nucleotide.
3. Inversion: A segment of nucleotides is reversed. Compare original CATTCACACG to CATTGCACAC — the segment "CACAC" is inverted to "GCACAC".
4. Duplication: A segment of nucleotides is repeated. Compare original CATTCACACG to CATTCACACCACG — the "CAC" segment is duplicated.
5. Substitution: One nucleotide is swapped for another. Compare original CATTCACACG to CATTCACACA — the final "G" is replaced with an "A".

Answer:

Type of Mutation	Original Nucleotide Sequence	Changed Nucleotide Sequence
insertion	CATTCACACG	CATTT CACACG
inversion	CATTCACACG	CATTGCACAC
duplication	CATTCACACG	CATTCACACCACG
substitution	CATTCACACG	CATTCACACA
