Mutations

Any change the sequence of nucleotides in DNA is called a

• Mutation

• Delection

• Duplication

• Inversion

Which shows a mutated segment of DNA? 
ATTCGC

• UAAGCG
• TAAGCG
• TAGGCG

if a single nucleotide base is added or deleted the entire reading frame will?

• shift, causing a frameshift mutation
• move, causing a delection
• move, causing an addition
• shift, causing a deletion

Why are framshift mutations harmful?

• They cause chromosomes to break
• Every amino acid following the mutation will be different
• They cause the DNA to relocated
• They burn out your clutch

mutations cause changes in traits because?

• mutations affect nucleosynthesis 
• Mutations affect gamete production 
• mutation affect meiosis
• mutations affect protein synthesis

What situation causes a translocation?

• Part of the chromosome is missing
• Part of the chromosome is attached backwards
• Part of the chromosome breaks off and attaches to a different chromosome
• Part of a chromosome is duplicated 

What are the building blocks of proteins called?

• DNA
• RNA
• Ribosomes
• Amino Acids

DNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTCGCAAG. This is an example of ___ mutation.

• Substitution
• Deletion
• Insertion
• Inversion

What is a Gene?

• A segment of RNA that encodes for a protein
• A chromosome
• A segment of DNA that encodes for a protein
• Your genome

Normal-
