Genotype ,phenotype Flashcards
What is the genotype pathways
primary transcription,Mrna to protein A and protein B
What do you know what about genetic coding
established very early in the evolution of life d has remained virtually unchanged
How many bases doe a coding sequences has in Mrna
Mrna coding sequence has 465 bases
What are the four type of mutation in Dna replication
Missence ,Nonssense ,Silent mutation ,Frameshift
Missense
-alters amino acid produced
Nonsense
-code for a stop codon ,premature termination of polypeptide
frameshift
-insertion of one base altering the reading of a codon
Homozygous
two identical alleles, same Pairs
Heterozygous
-two different alleles
epistatic
-one gene affecting the effect of an other
pleiotropic
-a gene that affect different part of other system
example ;lack of melanin not only affect the skin pigment but can affect hearing.
heterogametic
-two different kind of sex chromosomes
homogametic
-two of the same sex chromosomes
agouti(A)
influences where pigment is deposited
non-agoutie(aa)
