what are mutations?
directions: to answer the questions, read the paragraph below. then click the boxes and start typing.
a mutation is any change in the dna sequence. this could be as simple as replacing a nitrogenous base in the dna with a different base or as large as missing parts of a chromosome. mutations can result in a different protein being made, or they can have no effect at all. these genetic mutations can be inherited at birth or occur during an individual’s lifetime. examples include sickle cell anemia, cystic fibrosis, and melanoma.

1. \boxed{mutation} is any change in the dna sequence.
2. mutations can change the \boxed{} made during protein synthesis or have no affect at all.
3. individuals can \boxed{} mutations at birth or develop them over their lifetimes.

mutation in dna occurred during dna replication
original dna mutated dna

Explanation:

Question 2

From the paragraph, it says "Mutations can result in a different protein being made, or they can have no effect at all". So the blank should be filled with "protein" as it refers to what is made during protein synthesis.

The paragraph states "These genetic mutations can be inherited at birth or occur during an individual’s lifetime". So the appropriate word for the blank is "inherit" as it describes getting mutations at birth.

Answer:

protein
