DNA Mutations
Mutations are random changes in the DNA base sequence that occur continuously.
Do all mutations change the function of a protein?
What is DNA Mutations?
"A mutation is a change in the DNA sequence of an organism, which can result from errors during DNA replication or environmental factors."
What is meant by variation in a population?
Which characteristic is most likely to be influenced by both genes and the environment?
Which statement about mutations is correct?
Genetic Changes
Most mutations do not alter the protein or only slightly change its shape.
A few mutations may cause the protein to have a different shape (e.g., an active site of an enzyme no longer fits).
Non-coding parts of DNA can also mutate, affecting how genes are expressed.
Mutations can be silent, harmful, or occasionally beneficial for evolution.
