Questions and Answers (100% Pass)
Passive Transport - ✔️✔️the movement of substances across a cell membrane without
the use of energy by the cell
Diffusion - ✔️✔️the process by which molecules move from an area of higher
concentration to an area of lower concentration
Facilitated Diffusion - ✔️✔️movement of specific molecules across cell membranes
through protein channels
Osmosis - ✔️✔️diffusion of water through a selectively permeable membrane
Active Transport - ✔️✔️energy-requiring process that moves material across a cell
membrane against a concentration difference
Endocytosis - ✔️✔️the process by which a cell membrane surrounds a particle and
encloses the particle in a vesicle to bring the particle into the cell
Exocytosis - ✔️✔️the process by which a substance is released from the cell through a
vesicle that transports the substance to the cell surface and then fuses with the
membrane to let the substance out
Mutation - ✔️✔️change in a DNA sequence that affects genetic information
Gene regulation - ✔️✔️ability of an organism to control which genes are transcribed in
response to the environment.
DNA - ✔️✔️deoxyribonucleic acid, the material that contains the information that
determines inherited characteristics

Gene - ✔️✔️sequence of DNA that codes for a protein and thus determines a trait
Chromosome - ✔️✔️threadlike structure within the nucleus containing the genetic
information that is passed from one generation of cells to the next
Chromatin - ✔️✔️long strands of DNA found in the eukaryotic cell nucleus; condense to
form chromosomes
mRNA - ✔️✔️A type of RNA, synthesized from DNA, that attaches to ribosomes in the
cytoplasm and specifies the primary structure of a protein; also called messenger RNA.
rRNA - ✔️✔️ribosomal RNA; type of RNA that makes up part of the ribosome
tRNA - ✔️✔️The type of RNA that binds to specific amino acids and transports them to
the ribosome during protein synthesis
Transcription - ✔️✔️process in which part of the nucleotide sequence of DNA is copied
into a complementary sequence in RNA
Translation - ✔️✔️(genetics) the process whereby genetic information coded in
messenger RNA directs the formation of a specific protein at a ribosome in the
cytoplasm
Codon - ✔️✔️a specific sequence of three adjacent bases on a strand of DNA or RNA
that provides genetic code information for a particular amino acid
Anticodon - ✔️✔️group of three bases on a tRNA molecule that are complementary to an
mRNA codon
homologous chromosomes - ✔️✔️chromosomes that have the same sequence of genes,
that have the same structured, and that pair during meisosis
Fertilization - ✔️✔️process in sexual reproduction in which male and female reproductive
cells join to form a new cell
