Question 1

What is the definition of BASE PAIRING ?

Answer 1

principle that bonds in DNA can form only between adenine and thymine and between guanine and cytosine.

Question 2

Copying the Code. what is the role of DNA polymerase in copying DNA.

Answer 2

DNA polymerase, joins nucleotides to help make a
(synthesize) new complementary strand of DNA.

Question 3

What is THE REPLICATION PROCESS?

Answer 3

The DNA duplication process is called REPLICATION.

during replication, DNA strands separate, and two complementary strands are created - one from each matching the opposite.

Question 4

what is THE ROLE OF ENZYMES ?

Answer 4

an enzyme disconnects the bonds between the base pairs and unwinds the strands.
-Each strand becomes the model for the complementary strand. Then an enzyme called DNA POLYMERASE creates the bonds connecting nucleotides, and ensures that each new strand is an exact copy of its original.

Question 5

what are telomeres ?

Answer 5

THE TIPS OF EUKARYOTIC CHROMOSOMES ARE CALLED TELOMERES.

Question 6

replication of living cells
key question: How does DNA replication differ in prokaryotic cells and eukaryotic cells ?

Answer 6

DNA replication in prokaryotic cells starts from one point and continues in two directions until replication is complete. In eukaryotic cells, it begins at multiple points and continues outward until complete.

Question 7

Prokaryotic DNA replication

Answer 7

begins at a single point and moves in two directions until the entire chromosome is copied.

Question 8

Eukaryotic DNA Replication

Answer 8

is more complex and begins at multiple places on the DNA molecule, fanning out in two directions
