Pregunta 1
Pregunta
what is 3 bases on DNA called?
Respuesta
-
Codon
-
Triplet
-
Anti-codon
Pregunta 2
Pregunta
what is 3 bases called on tRNA?
Respuesta
-
codon
-
anti-codon
-
triplet
Pregunta 3
Pregunta
there is two stages of protein synthesis; translation and transcription
Respuesta
- True
- False
Pregunta 4
Pregunta
Translation happens before transcription
Respuesta
- True
- False
Pregunta 5
Pregunta
where does transcription occur?
Respuesta
-
nucleus
-
cytoplasm
-
ribosome
Pregunta 6
Pregunta
what happens in translation?
Respuesta
-
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
Pregunta 7
Pregunta
more than one codon, can code for an amino acid
Respuesta
- True
- False
Pregunta 8
Pregunta
what is the purpose of transcription?
Respuesta
-
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
Pregunta 9
Pregunta
what are the types of mutations that cause frameshift?
Respuesta
-
deletion
-
insertion
-
substitution
Pregunta 10
Pregunta
what type of substitution mutation changes the coded for amino acid?
Respuesta
-
silent
-
nonsense
-
missense
Pregunta 11
Pregunta
what type of mutation can be inherited?
Respuesta
-
somatic
-
gametic
Pregunta 12
Pregunta
what type of substitution mutation codes for a stop codon?
Respuesta
-
silent
-
nonsense
-
missense
Pregunta 13
Pregunta
silent mutation is the result of redundancy due to degeneracy
Respuesta
- True
- False
Pregunta 14
Pregunta
what is frameshift?
Respuesta
-
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
Pregunta 15
Pregunta
can mutations affect the metabolic pathway?
Respuesta
-
yes
-
no
Pregunta 16
Pregunta
what can determine a organism's phenotype
Respuesta
-
genotype
-
enviroment
-
nothing
-
upbringing
Pregunta 17
Pregunta
what are the things that cause mutations called?
Respuesta
-
genes
-
mutagen
-
bases
-
nonsense
Pregunta 18
Pregunta
the definition of metabolic pathway is linked biochemical reactions controlled by enzymes that maintain life processes in organisms
Respuesta
- True
- False
