Term
what is DNA
Definition

polymer of nucleotides

consists of deoxyribose sugar molecule, phosphate group, and nitrogen base 

Term
what are the four bases that form nucleotides of DNA
Definition
cytosine, adenine, thymine, guadine
Term
what is the difference between pyrimidine and purines
Definition

pyrimidine: cytosine and thymine

6 member ring 4 carbons 2 nitrogens

purines: adenine and guanine

6 & 5 member rings

Term
what is base pairing
Definition

the bridges

adenine to thymine

cytosine to guanine

Term
how does RNA differ from DNA
Definition

RNA is single strand-not helix

RNA uses ribose-not deoxyribose

RNA has cytosine and uracil-not thymine

Term
what is mRNA
Definition
the copy that is made of a gene that moves/travels to be translated
Term
what is a ribosome
Definition
group of basic proteins
Term
what is mutation regarding DNA
Definition
any error in copying DNA during DNA duplication or any damage done to DNA
Term
phenotype vs genetype
Definition

phenotype: what gene is seen physically (dominant)

geneotype: noting which gene is present in a particular chromosome  

Term
what is codominance/incomplete domicanace
Definition

when both trait are shown 

combo of phenotypes

pink flower example

Term
multifactoral
Definition
a number of genes are expressed in the phenotype
Term

sex linked
