DNA and Chromosomes Vocab
DNA- THe genetic material that carries information about the organism and is passed from parent to offspring
Double Helix- Describes the twisted, ladder-like shape of the DNA molecule
deoxyribose and phosphate- These two molecules alternate to form the twisted sides of the DNA molecule
nitrogen bases-The "rungs" of the ladder: Guanine-Cytosine. Adenine-Thymine.
chromosome- A wrapped up strand of DNA that contains genetic information in the forms of genes
gene- A section of DNA that controls a trait
allele- different forms of the same gene
chromosome pairs-We receive 1 set of chromosomes from each parent that contain the same genes in the same positions
punnet squares
A chart which shows all of the possible combinations of alleles that result from a genetic cross
Homozygous
heredity
heterozygous
phenotype
dominant allele
genotype
recessive allele
genetics
asexual and sexual reproduction
A mode of reproduction by which an organism arises from a single organism and inherit the identical genes from their parents
A mode of reproduction which an organism arises from two organisms and inherits half of its dna from each parent
