heredity Flashcards
polygenic trait
many genes for 1 trait
pleitropic
many trait; 1 gene
single gene/mendel train
1 gene, 1 trait
16th chromosome–earwax
allele
types of genes(i mean the representation)
polyploid cells
more than one gene code
heterozygous
different allele; Ww or wW
homozygous
WW ww
phenotype
traits that is visible on us
punnet square
to show the WW crossed ww
sex linked inheritance
Y is smaller than X
RNA vs DNA
ribose / deribose
ribose has one more oxygen
RNA has Uracil not thymine
dna discovered by
fredreich fischer: nuclein
rosalind franklin: DNA
what enzyme unwinds DNA
helicase
for leading strand of replication fork
dna polymerase adds nucleotides after RNA polymerase starts
dna polymerase works in 5’-3’ way
for lagging strand
okazaki fragments
dna ligase
joins the dnas
transcription
DNA— to rna– info sent
exons–expressed; introns–not expressed
translation
proteins made up
uac
methione
proteins
made of polypeptides made by tRNA
allopatric speciation
due togeography, diff features
