Flash cards of terms
when organisms make compounds needed by the cells
Anabolic reaction
Different versions of the same genes
Allele
the building blocks of elements
Atom
producers; organisms that make their own food
Autotroph
a series of pathways where molecules are broken down into smaller bits and energy is released
Catabolic reaction
the smallest organisms the building blocks of life
Cell
the complex of DNA and histones is called?
Chromatin
coils of DNA are bundled up into organized structures are called?
Chromosome
occurs when two alleles for a gene are both expressed but the characteristics are seen side by side
Codominance
type of cell formed when the plus and minus mating types come together
Diploid
a genetic trait that has a higher likelihood of being passed on to the next generation
Dominant
a pure substance made of only one kind of atom
Element
Proteins that speed up chemical reactions; break down molecules
Enzymes
the type of cells in multicellular organisms
Eukaryote
the two cells which come together to form a new organism
Gamte
the complete collection of a cell’s DNA genetic material
Genome
A segment of DNA on a chromosome that codes for a specific trait
Gene
the combination of alleles carried by an organism, all genes collectively, whether dominant or recessive
Genotype
each cell having a double copy of each chromosome, but missing its homologous pair
Haploid
consumers; organisms which depend on other organisms for their food
Heterotroph
when an organism has two different copies of an allele — one dominant and one recessive
Heterozygous
chromosomes organized into pairs
Homologous chromosomes
when an organism has two copies of the same allele — either both dominant or both recessive
Homozygous
occurs when two alleles are both expressed resulting in a blended phenotype
Incomplete dominance
