Across
  1. 2. an inorganic compound consisting of a phosphorus atom bonded to four oxygen atoms \
  2. 4. one of the four nitrogenous bases that make up the building blocks of DNA
  3. 6. a specific characteristic or feature of an organism, often inherited from parents, that can be observed and is determined by genes
  4. 8. a nitrogenous base, classified as a purine, that serves as one of the building blocks of DNA and RNA
  5. 11. a five-carbon sugar molecule that is a key component of DNA (deoxyribonucleic acid), forming the backbone of the DNA structure alongside phosphate groups
  6. 15. the observable characteristics or traits of an organism, which are determined by its genetic makeup (genotype) and influenced by environmental factors, such as diet or climate
  7. 16. a complex biological molecule, composed of long chains of nucleotides
  8. 17. the process by which traits or characteristics are passed from parents to their offspring through genes
Down
  1. 1. the specific way that nitrogenous bases in DNA (Adenine with Thymine, and Cytosine with Guanine) always pair up with each other, forming stable bonds through hydrogen bonding
  2. 3. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
  3. 5. organic molecules containing nitrogen atoms that are crucial components of nucleic acids like DNA and RNA, acting as the building blocks for storing genetic information
  4. 7. the process by which a cell copies its DNA molecule into two identical replicas
  5. 9. the three-dimensional structure of a DNA molecule, where two strands of nucleotides twist around each other
  6. 10. a weak electrostatic attraction between a partially positive hydrogen atom, covalently bonded to a highly electronegative atom like oxygen or nitrogen
  7. 12. 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. 13. a nitrogenous base, classified as a pyrimidine, that serves as one of the fundamental building blocks of DNA and RNA
  9. 14. one of the four primary nitrogenous bases found in DNA and RNA
