Pregunta 1
Pregunta
what are the stages of protein synthesis
Respuesta
-
translation
-
DNA replication
-
transcription
-
mutations
Pregunta 2
Pregunta
translation is the first stage of protein synthesis
Respuesta
- True
- False
Pregunta 3
Pregunta
where does transcription occur?
Respuesta
-
cytoplasm
-
nuclues
-
ribosomes
Pregunta 4
Pregunta
what is the purpose of transcription?
Respuesta
-
the purpose is to for mRNA to transcribe the code for a protein and so the original DNA doesn't get damaged leaving the nuclues
-
the purpose is to use mRNA to make a protein, so it can be used for cellular functions
Pregunta 5
Pregunta
whats the steps of transcription?
Respuesta
-
free nucleotides pair up to the template strand using the complementary base pairing rule, except U replaces T, to form the mRNA strand
-
the ribosome moves along and reads the mRNA
-
the DNA strand unwinds and unzips
-
the mRNA leaves the nuclues
-
the tRNA match the codon
Pregunta 6
Pregunta
A three base sequence on DNA is called a codon
Respuesta
- True
- False
Pregunta 7
Pregunta
where does translation occur?
Respuesta
-
nuclues
-
cytoplasm on the ribosomes
Pregunta 8
Pregunta
what is the purpose of translation?
Respuesta
-
the purpose to use mRNA to make a protein, so the protein can be used for cellular functions
-
the purpose is for the mRNA to transcribe the code and so the original DNA doesn't get damaged by leaving the nucleus
Pregunta 9
Pregunta
whats the three base sequence on mRNA called?
Respuesta
-
triplet
-
codon
-
anti-codon
Pregunta 10
Pregunta
whats the steps of translation?
Respuesta
-
the polypeptide chain folds up into a functional protein
-
the mRNA leaves the nuclues
-
the mRNA moves to the ribosome
-
the tRNA anti-codon matches the codon on mRNA using the complementary base pairing rule, except U replaces T
-
the ribosomes moves along and reads the mRNA
-
the codon codes for a specific amino acid, which the amino acids bond together by peptide bonds
-
the DNA splits to expose the template and coding strand
Pregunta 11
Pregunta
a three base sequence on tRNA is called anti-codon
Respuesta
- True
- False
