Final Study Guide Part IV Flashcards
Transcription
DNA polymerase used to produce mRNA
Translation
Protein produced from mRNA
Where in the cell does transcription and translation cover?
Transcription— nucleus
Translation— cytoplasm
Function of mRNA
Contains a copy of the genetic info in a gene and carries it to the ribosomes
Function of tRNA
Reads info on mRNA and translates it to the proper amino acid
Function of rRNA
Provides physical structure
Point mutation
Only one nucleotide is altered
Frameshift mutation
All codons are changed from the mutation onward
Autosomal trait
Traits not linked to sex chromosomes
Sex linked traits
Traits found in the X and Y chromosomes
Incomplete dominance
Presents as a blending of traits
Codominance
When no allele is dominant over another (blood types)
Homozygous dominant
When the genotype features two of the dominant alleles
Phenotype will show the dominant trait
Homozygous recessive
When the genotype features two of the recessive alleles
Phenotype will show the recessive trait
Heterozygous
Heterozygous is when a genotype contains two different alleles
Phenotype will feature the dominant trait
