DNA Replication and Functions

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Question
Answer
show a. Semi-conservative b. Replication is bidirectional and initiates at specific site c. Chromosomes ends require special replication d. Replication requires multiple enzymatic reactions  
🗑
What were the 3 models of replication propose?   show
🗑
Semi-conservative   show
🗑
Conservative   show
🗑
Dispersive   show
🗑
show a. 2 parental strands separate and serves as template strands. b. new nucleotides must obey the AT/GC rule c. end results with 2 new double helix and with same base sequence as original  
🗑
What is the origin of replication?   show
🗑
Which way is replication going?   show
🗑
How is bacteria and eukaryotic differ in their replication?   show
🗑
show it forms an opening called a replication bubble that forms two replication folks.  
🗑
show near the folk  
🗑
How is DNA synthesis begins?   show
🗑
show Made in direction fork is moving and synthesize as one long continuous strand and only require one primer  
🗑
Lagging strand   show
🗑
Synthesize Lagging strand   show
🗑
DNA helicase   show
🗑
show relieves additional coiling ahead of replication fork  
🗑
show keep parental strands single-stranded, so they can act as template  
🗑
DNA polymerase   show
🗑
Deoxynucleoside triphosphate   show
🗑
show 1. unable to initiate DNA synthesis if there is no template strand. Primase must make a short RNA primer and then primer is then removed and replaced with DNA 2. DNA polymerase can only add nucleotides in a 5 to 3 prime direction  
🗑
show 1. Polymerase III which is responsible for replication 2. DNA polymerase I has single subunit which is to remove RNA primer and fills in DNA 3. DNA II, IV involved in repair and replicate damage DNA  
🗑
What happen if there is not any template strand to go off?   show
🗑
Telomeres   show
🗑
Telomerase   show
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
