what is 3 bases on DNA called?
Codon
Triplet
Anti-codon
what is 3 bases called on tRNA?
codon
anti-codon
triplet
there is two stages of protein synthesis; translation and transcription
Translation happens before transcription
where does transcription occur?
nucleus
cytoplasm
ribosome
what happens in translation?
the ribosome reads the mRNA
the mRNA is coded for
the tRNA brings the coded for amino acid to the mRNA
the polypeptide chain is released and folds into a functional protein
the mRNA leaves the nucleus
more than one codon, can code for an amino acid
what is the purpose of transcription?
the purpose is for mRNA to transcribe the code for a protein so the original DNA doesnt get damaged
the purpose is to use mRNA to make a protein that can be used for cellular functions
what are the types of mutations that cause frameshift?
deletion
insertion
substitution
what type of substitution mutation changes the coded for amino acid?
silent
nonsense
missense
what type of mutation can be inherited?
somatic
gametic
what type of substitution mutation codes for a stop codon?
silent mutation is the result of redundancy due to degeneracy
what is frameshift?
when one base is inserted or deleted and the bases are moved over one resulting in different amino acids
when a base is swapped for another base
when the stop codon is coded for and results in the polypeptide chain not being completed and an unfunctional protein made
can mutations affect the metabolic pathway?
yes
no
what can determine a organism's phenotype
genotype
enviroment
nothing
upbringing
what are the things that cause mutations called?
genes
mutagen
bases
the definition of metabolic pathway is linked biochemical reactions controlled by enzymes that maintain life processes in organisms
