100
The first person to see a X-ray diffraction photograph in 1952
What is Rosalind Franklin?
100
Define telomere.
What is the tips of chromosomes.
100
The full name for RNA?
What is ribonucleic acid.
100
Structure/Model of RNA
What is single stranded.
100
The model of DNA
What is a double helix?
200
The base pairs for DNA
What is adenine, guanine, cytosine, thymine.
200
Define chromatin.
What is tightly packed DNA and proteins.
200
If DNA is the master plan for a building, RNA is the...
What is a blueprint or copy.
200
What is DNA
A nucleic acid made up of nucleotides joined into long strands to chains by covalent bonds.
300
What are James Watson and Francis Crick famous for?
The double helix model of DNA
300
What role does polymerase play in copying DNA?
Polymerase is an enzyme that joins individual nucleotides to produce a new strand of DNA.
300
What does mRNA stand for and what does it do?
Stands for Messenger RNA Carries copies of genetic information to other parts of the cell.
300
What does tRNA stand for what what does it do?
Stands for Transfer RNA. Transfers each amino acid to the ribosome.
300
The location of most DNA
What is the nucleus.
400
The difference in replication in prokaryotic cells and eukaryotic cells.
Prokaryotic cells: starts from a single point and proceeds in two directions until the entire chromosome is copied. Eukaryotic cells: begins at dozens or even hundreds of places on the DNA molecule, proceeding in both directions until each chromosome is completely copied.
400
What does rRNA stand for and what does it do?
Stands for Ribosomal RNA Proteins are assembled on these ribosomes. They can contain up to 80 differenent proteins.
400
Base pairs for RNA
What is adenine, guanine, cytosine and uracil
400
What is base pairing?
Explains Chargaff's rule. Only A-T would bond together and only C-G would bond together.
500
Explain Chargaff's Rule
A=T G=C always.
500
Where are two places DNA is found?
The nucleus and the mitochondria.
500
Explain RNA synthesis.
Transcription: segments of DNA serve as templates to produce complementary RNA molecules.
500
Three differences between RNA and DNA
1. RNA is single stranded (DNA is double stranded) 2. RNA contains ribose vs. deoxyribose 3. Uracil takes the place of Thymine
500
Define DNA replication.
The DNA molecule separates into two strands and then produces two new complementary strands following the rules of base pairing. These strands serve a template for the new strand of DNA.
