Biology

3. The passive movement of material from an area of high concentration to an area of low concentration across a concentration gradient
5. seals any gaps in new strands
7. Changes that occur at the nucleotide level
10. Changes to segments of DNA, involving many genes
12. Occurs when two dominant traits are both expressed
13. Separates DNA
14. Operates like carrier proteins used in facilitated diffusion, except they move molecules against their concentration gradient
15. Equal on both sides/balanced on both sides
17. Used for large molecules moving into the cell
18. Changes only one amino acid in the protein
19. Used for large molecules moving out the cell
20. Adds new nucleotides to new strands
21. Does not require energy input/movement of molecules
22. The diffusion of water across a selectively permeable membrane

1. Changes MANY amino acids
2. Change occurring in one nucleotide
4. used when making predictions about inheriting two independent traits
6. No true concentration
8. A mixing of traits when the heterozygous genotype is expressed
9. Change resulting in an early STOP codon
11. The process of moving cells from an area of low concentration to high concentration using a membrane protein
16. Nucleotide changes, but no change to the resulting amino acid
