Question

Answer this and you will get a medal!
5. What enzyme makes it less likely that DNA will be lost from telomeres during replication?

Answer 1

polymerase

Answer 2

meanie, making somebody else answer while im yelled at by u T_T and yes shes right.

Answer 3

MidnightMemories please answer this, 6. How does this enzyme work?

Answer 4

Meheheh, sorry I just am a whiz a biology!

Answer 5

really?

Answer 6

Yuppers! Been studying it for 2 years!

Answer 7

midnight, i was referring to something else,

Answer 8

Ohhhh.

Answer 9

hey guys, 7. What is a replication fork?

Answer 10

nice

Answer 11

i already had the answer, but rob yelled at me, via message, and i had to reply, i kept going to her new questions and he was mad that i wouldnt let others get a medal.

Answer 12

"A replication fork is just the junction where the double-stranded DNA splits apart into 2 single strands.

Helicase opens up the DNA duplex, which creates 2 replication forks, then polymerases start to build new daughter chains and the forks get further and further away from each other as the strands are elongated."

Answer 13

you already have 3 medals dude!

Answer 14

im trying to get light green colors o.O

Answer 15

oh and please answer this, 8. Does DNA replication take place in the same direction along both strands of the DNA molecule that is being replicated? Explain your answer.

Answer 16

Yes, if you're talking in terms of 3' and 5' ends.

One strand is replicated away from the replication origin; the other is replicated toward the replication origin.

Answer 17

Agreed.

Answer 18

here try to answer this, 2. The master plan of a building shows how to build and place important parts of the building, such as walls, pipes, and electrical outlets. On the building site, workers use copies of the master plan called blueprints to show them what to do. The master plan is kept in the office. Explain how mRNA works like a blueprint in constructing proteins.

Answer 19

DNA = MASTER PLAN
MRNA = COPIES OF MASTER PLAN

Answer 20

hmm the answer is actually \(\color{red}{telomerase}\). It's a reverse transcriptase (makes DNA from RNA templates) that elongates telomeres as they get shorter as a result from DNA replication.
