Across
- 3. The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid
- 5. the addition of one or more nucleotide base pairs into a DNA sequence
- 6. deoxyribonucleic acid, a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
- 8. polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes
- 10. discovered the molecular structure of deoxyribonucleic acid (DNA)
Down
- 1. a mutation that exchanges one base for another
- 2. the loss or excision of a section of genetic code, or its product, from a nucleic acid or protein sequence
- 4. discovered two rules that helped lead to the discovery of the double-helix structure of DNA
- 7. a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring
- 9. act as a messenger carrying instructions from DNA for controlling the synthesis of proteins
