Where does DNA replication take place
Nucleus
|
Explain the replication of DNA
A new strand of DNA and an old strand of DNA. The original DNA is used as a template.
|
Replicate this strand to mRNA: ACGTAGCTAACG
UGCAUCGAUUGC
|
What is the sequence of genetics?
DNA --> RNA --> protein
|
Explain what might happen if the mRNA is mutated during transcription
May copy the instructions wrong which results in the wrong polypeptide being made
|
RNA from a bear and RNA from a sunflower both contain these
sugar ribose and uracil
|
What nitrogen bases does RNA have
A C G U
|
The sequence of ______ in a DNA molecule determines the protein that will be produced
nucleotides
|
What is a gene
a portion of chromosome that codes for a single protein
|
tRNA brings amino acids to the
ribosomes
|
A DNA nucleotide could contain the following molecules
deoxyribose thymine and a phosphate
|
What nitrogen bases does DNA have
ACGT
|
During ______ the cell uses information from mRNA to make polypeptides
translation
|
What is a nucleotide
subunit that makes up nucleic acid
|
tRNA has
anticodons
|
In nucleotides, what do A C G T represent
nitrogen bases
|
What shape is DNA
double helix
|
How many amino acids are in this sequence: AUGAUC
2
|
What is a codon
a set of 3 nucleotides that code for a specific amino acid
|
tRNA transfers amino acids during
translation
|
the cellular process of creating two new DNA molecules from one original copy is called
replication
|
what shape is RNA
single strand
|
During protein synthesis, what does mRNA do?
it delivers instructions for making proteins to the ribosome
|
What is an amino acid
subunit that makes up proteins
|
The step of protein synthesis that occurs in the cytoplasm is
translation
