Allele - ANSWER Form of a gene. Each characteristic has two alleles.
Recessive - ANSWER trait that will only appear in the phenotype if organism inherits
two of them; covered up by the dominant gene
Gamete - ANSWER sex cell; sperm or egg
Adenine - ANSWER A base thats found in DNA. It will only bond with Thymine.
Amino acid - ANSWER Building blocks of protein
Asexual reproduction - ANSWER Reproduction of identical offspring from a single
parent. No gametes involved
Autosomes - ANSWER Any chromosome other than the sex chromosomes.
Base - ANSWER One of four chemicals which make up the 'rungs' of DNA; A;T;C;G
Base-pair - ANSWER Two bases making each rung of DNA: either A-T or C-G
Biodiversity - ANSWER The variation in species within an ecosystem
1
, Cell - ANSWER The structural and functional unit of all living things
Cell division - ANSWER The formation of two or more daughter cells
Chromosome - ANSWER Thread-like structures bearing genes that are found in the
nucleus of a cell
Characteristic - ANSWER A distinctive inherited feature of organism
Cloning - ANSWER A process that produces identical genetic individuals
Cytosine - ANSWER A base pair found in DNA. It will only bond with Guanine.
DNA - ANSWER Deoxyribonucleic acid. A molecule found in the nucleus of cells which
provides an individuals genetic code
DNA replication - ANSWER The process whereby DNA makes an exact copy of itself
Dominant - ANSWER An allele that controls the phenotype regardless of what the
other allele is
Double-helix - ANSWER a term used to describe the structure of DNA - a spiral ladder
shape
Fertilization - ANSWER The fusion of a male and female gamete to form a zygote
Gamete - ANSWER A sex cell. Ovum (egg) in females or sperm in males. Ovule and
pollen in plants.
