Once an mRNA is created, the next step is:
proofreader enzymes check the polypeptide to be sure it is correct
it stays in the nucleus to build the protein with tRNA help
the tRNA bring the amino acids to it
it leaves the nucleus and goes to the ribosome
Use the picture to answer the following question: Structure D is
codon
anticodon
If the mRNA reads GUA, what tRNA anticodon would be necessary to drop off the amino acid?
CAT
CAA
CAU
GAU
Use the picture to answer the following: the entire structure labeled at E is
mRNA
tRNA
rRNA
Amino Acid
What is the COMPLEMENTARY strand of this DNA molecule: CGA-TTG-GCC-ACG
GGT-AAC-GCC-ACG
GCT-AAC-CGG-TGC
GCT-AAC-CGG-TGF
GCT-AAC-CCC-TGC
How many codons would be required to specify a series of 3 amino acids?
12
6
3
9
Which of these is found in both DNA and RNA?
thymine
Adenine
deoxyribose
ribose
TRANSCRIBE the following DNA strand into an mRNA strand: CGA-TTG-GCC-ACG
GCU-AAC-CGG-UGC
GCT-AAC-CGG-TGC
GCU-AAC-CGG-GCG
this is not a DNA molecule
Transcription
Occurs in the nucleus and creates mRNA
Occurs in the ribosome and makes mRNA
Occurs in the nucleus and makes a protein
Occurs in the ribosome and makes a protein
The genetic code of any organism is determined by
the sequence of anticodons in the tRNA
the arrangement of sugar and phosphate on the DNA ladder
the sequence of the proteins that are built
the sequence of nitrogen bases in the DNA
The number, type and order of nucleotides in DNA specifies (tells) the order of what?
proteins
genes
amino acids
peptide bonds
Use the picture to answer this question: Structure C is
the mRNA strand
the tRNA strand
the growing polypeptide (protein) strand
the DNA strand
The Central Dogma of Molecular Biology is
DNA>RNA>tRNA
gene>protein>DNA
DNA>RNA>protein
protein>RNA>DNA
Use the picture for this question: The organelle responsible for protein synthesis labeled A is:
an anticodon
a ribosome
a codon
an amino acid
Use the picture for this question: The process shown here is
cell division
DNA replication
translation
transcription
The process of creating a polypeptide is
done in the nucleus
translation
replication
transcription
Most errors in DNA are not harmful to you, why?
The error is not copied by the mRNA
The error is corrected when mRNA is created
The proofreader enzymes always fix the errors
The error is not in a important part of a gene
Use the Genetic Code Wheel to help: if the mRNA reads GGA, what amino acid does it code for?
serine
CCU
glutamic acid
glycine
Use the Genetic Code Wheel to TRANSLATE the following mRNA strand into the 4 amino acids: GCU-AAC-CGG-UGC
Alanine-Asparagine-Arginine-Cysteine
Alanine-Glutamine-Arginine-Cysteine
Alanine-Asparagine-Arginine-Leucine
Alanine-Lysine-Arginine-Leucine
A chain of connected amino acids is called
a mRNA
a chromosome
a polypeptide
a monomer
The first step in DNA replication is:
enzymes proofread the new DNA strand
the enzymes unzip the DNA
the cell divides into 2 cells
placement of nucleotides onto open sides
In DNA electrophoresis what is purpose for the buffer?
It helps to cut the DNA strands into different lengths
It helps to move the electrical current through the sample
It helps to identify which sample is the father's DNA
It helps to dye the DNA bands to see them better
How are the amino acids held together in a growing polypeptide chain?
Codon bonds
Peptide bonds
Purine bonds
Hydrogen bonds
