Across
- 1. Cells- cells that have the capacity to self-renew and generate multiple mature cell types.
- 3. A small RNA molecule that plays a key role in protein synthesis.
- 6. plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.
- 8. Regulation- The process of turning genes on and off
- 10. a sugar derived from ribose by replacing a hydroxyl group with hydrogen
- 11. Instructs cells in the body to make specific proteins.
- 15. Strand- a newly synthesized strand of DNA that is copied via the addition of complementary nucleotides from one strand of pre-existing DNA during DNA replication.
- 20. The space between the end of a nerve cell and another cell.
- 22. the fundamental units of the brain and nervous system
- 25. A pyrimidine derivative, it is paired with adenine in double-stranded DNA.
- 26. Bases- Bases pair up with each other in a consistent way.
- 29. Villi- Tiny hair-like projections that line the inside of the small intestine. They contain blood vessels and help absorb nutrients.
- 31. vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.
- 32. A chain of amino acids that form from peptide bonds.
- 33. Compound found in living tissue as a constituent base of RNA. In DNA its place is taken by thymine.
- 34. Carries genetic information that is translated by ribosomes into various proteins necessary for cellular processes.
- 35. a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule
Down
- 2. The process by which DNA is copied to RNA
- 4. The basic unit of heredity passed from parent to child.
- 5. Bonds- a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
- 7. Cells- specialized animal cells which can shorten their length using a series of motor proteins specially arranged within the cell.
- 9. Cell- A type of cell that receives and sends messages from the body to the brain and back to the body.
- 12. A purine derivative, it is paired with thymine in double-stranded DNA.
- 13. Strand- the pre-existing single strand of DNA that is copied into a new strand of DNA via complementary base pairing.
- 14. characterized by or exhibiting biological specialization
- 16. A purine derivative, it is paired with cytosine in double-stranded DNA.
- 17. a genetically determined characteristic
- 18. Cell/Stomata- surrounds each stoma on the leaf surface
- 19. The molecule inside cells that contains the genetic information responsible for the development and function of an organism.
- 21. Replication- The process by which the genome's DNA is copied in cells.
- 23. the processes by which immature cells become mature cells with specific functions.
- 24. your body's chemical messengers.
- 26. It is paired with guanine in double-stranded DNA.
- 27. RNA is used to produce proteins
- 28. Blood Cells- carry oxygen from our lungs to the rest of our bodies.
- 30. Cells- small, compact cells, highly specialized for the task of fertilizing an egg
