100
Where does DNA replication take place
Nucleus
100
Explain the replication of DNA
A new strand of DNA and an old strand of DNA. The original DNA is used as a template.
100
Replicate this strand to mRNA: ACGTAGCTAACG
UGCAUCGAUUGC
100
What is the sequence of genetics?
DNA --> RNA --> protein
100
Explain what might happen if the mRNA is mutated during transcription
May copy the instructions wrong which results in the wrong polypeptide being made
200
RNA from a bear and RNA from a sunflower both contain these
sugar ribose and uracil
200
What nitrogen bases does RNA have
A C G U
200
The sequence of ______ in a DNA molecule determines the protein that will be produced
nucleotides
200
What is a gene
a portion of chromosome that codes for a single protein
200
tRNA brings amino acids to the

deoxyribose thymine and a phosphate
300
What nitrogen bases does DNA have
ACGT
300
During ______ the cell uses information from mRNA to make polypeptides
translation
300
What is a nucleotide
subunit that makes up nucleic acid
300
tRNA has
anticodons
400
In nucleotides, what do A C G T represent
nitrogen bases
400
What shape is DNA
double helix
400
How many amino acids are in this sequence: AUGAUC
2
400
What is a codon
a set of 3 nucleotides that code for a specific amino acid
400
tRNA transfers amino acids during
translation
500
the cellular process of creating two new DNA molecules from one original copy is called
replication
500
what shape is RNA
single strand
500
During protein synthesis, what does mRNA do?
it delivers instructions for making proteins to the ribosome
500

subunit that makes up proteins
500
The step of protein synthesis that occurs in the cytoplasm is
translation
