DNA Structure
This is the site of DNA replication.
What is nucleus?
The base RNA uses that is not in DNA
What is U?
A short segment of DNA that codes for a specific protein.
What is a gene?
We use PCR in forensics to copy tiny amounts of this molecule found in cells.
What is DNA?
True or false: When DNA replicates, each new DNA strand has one original part and one new part.
What is TRUE?
DNA is shaped like a double helix. RNA is shaped like this.
What is a single strand?
DNA found at a crime scene can be compared to this to help figure out who was there.
What is a suspect's DNA? (Accept: A person’s DNA / the suspect)
True or False: PCR makes only one copy of DNA each time.
What is FLASE?
What is negative?
Replication is different from PCR in one big way—replication happens inside the cell, but PCR happens where?
What is in a lab or test tube?
DNA stays safe in the cell's nucleus, but RNA can do this.
What is leave the nucleus to carry instructions?
Two organisms that are more closely related will have more similarities in this.
What is DNA sequences/genes?
At a crime scene, a single drop of blood may not be enough to test—so scientists use PCR to do this with the DNA.
What is make more copies? (also accept: amplify it)
This is the name for the building blocks of DNA that are added when it's copied.
What is nucleotide or What is a base?
During DNA replication, the complementary DNA strand for ACGTCC would be:
What is TGCAGG?
If the DNA sequence is GCAATC, this is the mRNA sequence.
What is CGUUAG?
After copying the DNA with PCR, scientists use this method to separate DNA by size and see the pattern.
What is gel electrophoresis?
PCR is like a biological photocopier. Which three steps are repeated to copy DNA?
What are denaturation, annealing, and extension?
DNA stands for this long word
What is deoxyribonucleic acid?
Why is DNA replication important before a cell divides?
What is so each new cell gets an exact copy of the DNA?
The location mRNA is translated.
Where is the ribosome?
If you accidentally mixed up your suspect samples before PCR, what could happen to your case?
What is you might accuse the wrong person or get the wrong result?
Name one thing that both DNA replication and PCR have in common.
What is they both make copies of DNA? (Also accept: They both use DNA as a template.)
