,What is the basic unit of life? Cell
What are the three domains of life? Bacteria, Archaea, and Eukarya
What is the function of mitochondria? Produce ATP through cellular respiration
What is the function of ribosomes? Protein synthesis
What is the difference between prokaryotic and eukaryotic Prokaryotes lack a nucleus and membrane-bound organelles; eukaryotes have both
cells?
What is the cell membrane composed of? Phospholipid bilayer with embedded proteins
What is the function of the Golgi apparatus? Modify, package, and transport proteins
What is the endoplasmic reticulum? Network of membranes involved in protein and lipid synthesis
What is the difference between smooth and rough ER? Rough ER has ribosomes and makes proteins; smooth ER synthesizes lipids
What is the function of lysosomes? Digest and recycle cellular waste
What is osmosis? Diffusion of water across a semi-permeable membrane
What is diffusion? Movement of molecules from high to low concentration
What is active transport? Movement of molecules against concentration gradient using ATP
What is facilitated diffusion? Passive transport using protein channels
What is endocytosis? Process of engulfing materials into the cell
2026
,What is exocytosis? Process of expelling materials from the cell
What is the function of the nucleus? Store and protect DNA; control cell activities
What are chromosomes? Condensed structures of DNA and proteins
How many chromosomes do humans have? 46 (23 pairs)
What is DNA made of? Deoxyribonucleotides (sugar, phosphate, nitrogenous base)
What are the four nitrogenous bases in DNA? Adenine, Thymine, Guanine, Cytosine
What is the complementary base pairing rule? A pairs with T; G pairs with C
What is RNA? Ribonucleic acid; single-stranded nucleic acid
What are the three types of RNA? mRNA, tRNA, and rRNA
What is transcription? Synthesis of RNA from DNA template
What is translation? Synthesis of protein from mRNA template
What is a codon? Three-nucleotide sequence that codes for an amino acid
What is a mutation? Change in DNA sequence
What is a point mutation? Single nucleotide change in DNA
What is mitosis? Cell division producing two identical diploid cells
2026
, What are the phases of mitosis? Prophase, Metaphase, Anaphase, Telophase
What is meiosis? Cell division producing four haploid gametes
What is crossing over? Exchange of genetic material between homologous chromosomes during meiosis
What is independent assortment? Random distribution of chromosomes during meiosis
What is the difference between diploid and haploid? Diploid has two sets of chromosomes (2n); haploid has one set (n)
What is a gene? Segment of DNA that codes for a protein or trait
What is an allele? Alternative form of a gene
What is a genotype? Genetic makeup of an organism
What is a phenotype? Observable characteristics of an organism
What is dominant inheritance? Trait expressed when at least one dominant allele is present
What is recessive inheritance? Trait expressed only when two recessive alleles are present
What is codominance? Both alleles are expressed equally in heterozygotes
What is incomplete dominance? Heterozygote shows intermediate phenotype
What is Mendel's Law of Segregation? Allele pairs separate during gamete formation
What is Mendel's Law of Independent Assortment? Genes for different traits segregate independently
