Down:
1) the specific, consistent hydrogen bonding between nitrogenous bases in DNA and RNA2) large, complex biomolecules (macromolecules) essential to all living organisms, composed of one or more long chains of amino acids linked by peptide bonds3) a specialized, often membrane-bound, structure within a cell that performs specific, essential functions, analogous to organs in the body8) the process by which genetic information (DNA) is passed from parents to their offspring during reproduction9) essential, non-membrane-bound organelles found in all living cells that act as the site of protein synthesis10) a group of structurally and functionally related organs and tissues that work together to perform major physiological tasks, such as digestion, circulation, or movement11) a self-replicating, double-stranded helical molecule found in all living cells that carries the genetic code required for the growth, development, function, and reproduction of organisms13) the organic building blocks of proteins14) a vital, typically single-stranded nucleic acid present in all living cells that acts as a messenger between DNA and ribosomes to produce proteins15) the production or creation of complex molecules (like proteins, DNA, or carbohydrates) from simpler components, typically aided by enzymes16) essential chemical substances—including carbohydrates, lipids, proteins, vitamins, minerals, and water—that organisms ingest or absorb to sustain life, generate energy, enable growth, and facilitate repair |
Across:
2) a critical tumor-suppressor protein4) a thread-like structure located inside the nucleus of animal and plant cells, composed of a single, highly coiled molecule of DNA wrapped around proteins (histones)5) one of two or more alternative versions of a gene that arise by mutation and are located at the same specific spot (locus) on a chromosome6) the fundamental biological process by which information encoded in a gene (DNA) is used to synthesize functional products, typically proteins or functional RNA molecules7) a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.12) a specialized structure composed of different types of tissues that work together to perform specific, complex functions within a multicellular organism17) any individual living entity that functions as a self-contained unit, possessing the ability to grow, reproduce, maintain homeostasis, and respond to stimuli18) a genetic process occurring during prophase I of meiosis, where homologous chromosomes pair up and exchange segments of DNA between non-sister chromatids19) an essential ATP-dependent enzyme that unwinds double-stranded DNA or RNA by breaking hydrogen bonds between complementary base pairs20) any individual living entity that functions as a self-contained unit, possessing the ability to grow, reproduce, maintain homeostasis, and respond to stimuli21) a group of similar cells, along with their extracellular matrix, that are specialized to work together to perform a specific function in multicellular organisms22) a permanent, random change in the nucleotide sequence of an organism's DNA23) an abnormal, excessive growth of body tissue characterized by rapid cell division and impaired cell death |
