protein synthesis and mendel test Flashcards
(30 cards)
genome
entire set of an organism’s DNA
genes
an area of DNA in chromosomes
transcription
turns DNA into mRNA, happens in the nucleus
mRNA
single-stranded, instead of T they have U
TCAG
AGUC
translation
turning mRNA into a protein, happens in the cytoplasm
the mRNA is changed into an amino acid chain in the
ribosome
CODON chart
used to translate mRNA into amino acids
phenotype
an organisms physical trait
genotype
the alleles and organism has
TT
homozygous dominant
tt
homozygous recessive
Tt
heterozygous
homozygous
when there are two of the same alleles
heterozygous
when there are two different alleles
Gregor Mendel
discovered that pea plants can have different phenotypes
Mendel’s law of dominance
some phenotypes are expressed over others
recessive trait
the less common trait
dominant trait
the more common trait
PP or Pp
dominant phenotype
pp
recessive pheno type
Yy
heterozygous
yy
homozygous recessive
YY
homozygous dominant
