  • Q1
    A variation of a gene's nucleotide sequence (an alternative form of a gene)
    Allele
    30s
  • Q2
    The series of events that take place in a cell leading to its division and duplication. The main phases of the cell cycle are interphase, nuclear division, and cytokinesis
    Cell Cycle
    30s
  • Q3
    A single piece of coiled DNA and associated proteins found in linear forms in the nucleus of eukaryotic cells and circular forms in the cytoplasm of prokaryotic cells; contains genes that encode traits. Each species has a characteristic number of chromosomes
    Chromosomes
    30s
  • Q4
    The final phase of the cell cycle resulting in the split of the cytoplasm
    Cytokinesis
    30s
  • Q5
    The process in which DNA makes a duplicate copy of itself
    DNA Replication
    30s
  • Q6
    A specialized cell (egg or sperm) used in sexual reproduction containing half the normal number of chromosomes in a somatic cell
    Gamete
    30s
  • Q7
    A sequence of nucleotides composing a segment of DNA that provides a blueprint for a specific hereditary trait
    Gene
    30s
  • Q8
    The process in which a nucleotide sequence of a gene is used to make a functional product such as protein or RNA
    Gene Expression
    30s
  • Q9
    The longest lasting phase in the cell cycle in which a cell performs the majority of its functions, such as preparing for nuclear division and cytokinesis
    Interphase
    30s
  • Q10
    A two phase nuclear division that results in the eventual production of gametes with half the normal number of chromosomes
    Meiosis
    30s
  • Q11
    A nuclear division resulting in the production of two somatic cells having the same genetic complement as the original cell
    Mitosis
    30s
  • Q12
    The process in which sister chromatids fail to separate during and after mitosis or meiosis
    Nondisjunction
    30s
  • Q13
    The process in which amino acids are arranged in a linear sequence through the processes of transcription of DNA or RNA and the translation of RNA to a polypeptide chain
    Protein Synthesis
    30s
  • Q14
    The process in which the DNA molecule uncoils and separates into two strands. Each original strand becomes a template on which a new strand is constructed, resulting in two DNA molecules identical to the original DNA molecule
    Semiconservative Replication
    30s
  • Q15
    The process in which a strand of messenger RNA (mRNA) is synthesized by using the genetic information found on a strand of DNA as a template
    Transcription
    30s
