the sequence of the amino acids is dictated by

the sequence of nitrogen bases in the DNA/mRNA

a difference in prokaryote gene expression and eukaryote gene expression

transcription and translation can occur at the same time

Which of these is NOT a function of RNA?

stores the genetic information for the entire organism

Where does translation occur?

in the cytoplasm at the ribosome

adds RNA nucleotides to the 3' end of the growing RNA strand

Questions 26

Answers

1
The monomer of proteins is
amino acids
nucleic acids
fatty acids
citric acid
2
a piece of a gene has 15 nucleotides; after a mutation it has 14; this is a/an
inversion
insertion
deletion
substitution
3
manufacturer or ribosomes
nucleus
nucleolus
mitochondria
rough ER
4
makes up part of the ribosome
mRNA
DNA
tRNA
rRNA
5
the sequence of the amino acids is dictated by
whether the protein is being made in the cytosol or on ER
the sequence of nitrogen bases in the DNA/mRNA
whether it is the maternal or the paternal homolog
the type of R group on the amino acid
6
RNA synthesis
transcription
replication
RNA processing
translation
7
which does not code for an amino acid
stop codon
anticodon
start codon
DNA triplet
8
codes for 1 amino acid
a chromosome
a gene
3 nucleotides
1 nucleotide
9
point mutation
never causes a frameshift
involves a single nucleotides
cannot be a substitution
always is silent
10
a premature stop codon results in
nonsense
missense
none of these is correct
sense
11
Which organelle packages and ships the protein to its destination for use by the cell?
rough ER
mitochondria
Golgi
nucleus
12
insertions and deletions usually result in
no change in the protein
a frameshift
sense
silent mutation
13
a difference in prokaryote gene expression and eukaryote gene expression
translation doesn't occur in prokaryotes
transcription and translation can occur at the same time
transcription occurs second in prokaryotes
both transcription & translation occur in prokaryote nuclei
14
DNA --> RNA
translation
mitosis
replication
transcription
15
protein synthesis
in the nucleus
translation
transcription
mitochondria
16
Which of these is NOT a function of RNA?
stores the genetic information for the entire organism
part of the structure of the ribosome
carries an amino acid from the cytoplasm to the ribosome
carries the message from the nucleus to the cytoplasm
17
Where does translation occur?
in the nucleus
in the mitochondria
in the cytoplasm at the ribosome
in the Golgi
18
A difference between DNA and RNA includes
DNA contains a phosphate group
guanine pairs with cytosine
only RNA contains ribose
adenine can be a nitrogen base
19
Which of these is never part of an RNA nucleotide
thymine
cytosine
phosphate group
5-carbon sugar
20
RNA polymerase
builds a primer so DNA nucleotides can be joined on
adds RNA nucleotides to the 3' end of the growing RNA strand
adds DNA nucleotides to the growing strand
joins together Okasaki fragments
21
A gene has 303 nucleotides, resulting in a protein with 100 amino acids. Why aren't there 101?
a translocation occurred
a mutation occurred
the last 3 nucleotides are a stop codon
a deletion occurred
22
Most protein production occurs during
G1 of interphase
meiosis
S of interphase
mitosis
23
start codon
AUG
GUA
AGU
TAC
24
three mRNA nucleotides
anticodon
Okasaki fragment
triplet
codon
25
three tRNA nucleotides
codon
anticodon
gene
triplet
26
How does mRNA get out of the nucleus?
active transport
nuclear pore
magic
diffusion
