DNA Mutations/Natural Selection

2. A type of mutation in which the nucleotide changes results in the replacement one one protein building block with another made from the gene.
5. A type of mutation that occurs when there is an addition or loss of nucleotides that shifts the grouping and changes the code for all downstream amino acids.
7. More offspring are produced each year than local resources can support leading to a struggle for resources.
9. An English naturalist, geologist and biologist, best known for his contributions to the science of evolution.
11. Some traits are consistently passed on from parent to offspring. Such traits are heritable, whereas other traits are strongly influenced by environmental conditions and show weak heritability.
13. A type of mutation that occurs when a stretch of one or more nucleotides in a gene is copied and repeated next to the original DNA sequence.
14. A theory proposed by Charles Darwin which states that it is a process whereby organisms better adapted to their enviornment tend to survive and produce more offspring.
15. A type of mutation that replaces one DNA building block with another.

1. A type of mutation in which the nucleotides change the altered DNA sequence results in a stop signal that prematurely signals the cell to stop building a protein.
3. Individuals possessing traits well suited for the struggle for local resources will contribute more offspring to the next generation.
4. A type of mutation that changes more than one nucleotide in a gene by replacing the original sequence with the same sequence in reverse order.
6. A type of mutation that changes the DNA sequence by adding one or more nucleotides to the gene.
8. A type of mutation that changes the DNA sequence by removing at least one nucleotide in a gene.
10. Organisms (within populations) exhibit individual variation in appearance and behavior.
12. The molecule that contains the genetic code of organisms.
