five
How many carbons are in one chain of DNA
|
Prokaryotes - one
Eukaryotes - many, lots
(Two part question)
How many origins do prokaryotes have when undergoing replication? What about Eukaryotes? |
It is
Is it common to see multiple ribosomes going through the process of translation on a single mRNA strand?
|
sausage
50 points = easy
What does the sausage model resemble? |
substrate at the active site
What does an inhibitor compete with?
|
|
histones
What is the DNA wrapped around to be supercoiled?
|
DNA-->RNA-->Protein
Place these in the correct order:
- RNA - Protein - DNA |
inside of the nucleus
Where are ribosomes constructed?
|
structural
movement transport defense
Name 2 of the four main functions of proteins
|
the rate of reaction to decrease
What does an inhibitor cause?
|
|
does not code - intron
codes - exon
(Two part question)
What is a fragments of DNA that codes for a protein called? What is a DNA fragment that does not code for one called? |
Because no introns exist
Why do Prokaryotes not require post-trancription processing?
|
2/3
What percentage of a Ribosome is rRNA?
- 1/3 - 2/3 - 3/3 - Ribosomal RNA does not exist |
20
How many amino acids are there?
(an answer within 5 is correct) |
exothermic
Reactants of a chemical reaction need to gain energy before they can undergo the reaction. This means that . a majority of biological reactions are...
|
|
DNA that has no coding function
What is structural DNA?
|
helicase
What is the name of the protein that unwinds the double helix at replication forks?
|
- lysosomes
- outside the cell
What TWO places will proteins made by ribosomes bound to the ER go?
|
hydrophilic
Amino acids with non-polar side chains are hydrophobic. What are they called if they have polar side chains?
|
Proteins, catalysts, long chains of amino acids, specific 3-D shape, active site, substrates, allow reactions to occur quickly, lowers activation energy required, etc.
Describe at least three characteristics of enzymes.

Satellite DNA
What type of DNA are the centromeres of chromosomes made of?
|
- introns = 24%
- exons = 1-2% - highly repetitive sequences = 45%
(Three part question)
Name the frequency percentages that the various types of DNA make up? (the three parts of DNA below do not equal 100% of DNA) - introns - exons - highly repetitive sequences (ALL THREE ANSWERS MUST BE WITHIN TEN OF THE CORRECT ANSW |
- initiation
- elongation - translocation - termination
1000 point question = hard
Name the four phases of translation. good luck. |
fibrous - long, narrow shape; insoluble
globular - 3-D, water-soluble, (must have at least one for each)
What are the differences between fibrous and globular proteins?
|
The product of the enzyme rebinds to the enzyme and keeps it from making more of the product.
Describe what end-product inhibition briefly?
