DNA
The shape of a DNA molecule
Double Helix
The storage center for the cell
Vacuole
The study of cells
cytology
The trait that does not show up with the dominant allele is present
Recessive
Where proteins are made
Ribosomes
Cytosine
Makes ATP, is the "powerhouse" of the cell
Mitochondria
The Father of Genetics
Gregor Mendel
When two different alleles are present
heterozygous
The cell membrane is made of __________________ that cluster back-to-back, forming a two-layered structure
Phospholipids
The phase of the cell cycle in which replication occurs
Sythesis
"shipping center of the cell"; packages proteins into vesicles and sends them to their final locations
Golgi Apparatus
The first to see and describe a cell under a microscope
Robert Hooke
When both alleles are identical
homozygous
catalysts that break down old proteins for recycling
Enzymes
The location where DNA is found
The nucleus
The jellylike fluid inside the cell
Cytosol
1. All living things are made of cells
2. All cells come from preexisting cells
The cell theory
The actual combination of the alleles
genotype
The cytoskeleton is composed on these
microtubules
Nucleotides are made up of these three parts
phosphate group, sugar, and nitrogen base
This is a network of flexible reinforcement fibers beneath the phospholipid bilayer
membrane skeleton
The membrane around the nucleus
Nuclear Envelope
The physical expression of the alleles
phenotype
The contents of animal cells are separated from the outside environment by this barrier
Cell membrane
