Answer:
The correct option is b. DNA ligase
Explanation:
DNA ligase is an enzyme that joins DNA fragments. If two DNA fragments or molecules have complementary ends, the ligase can join them together to form a single and intact DNA molecule, without interruptions. This is because the ligase enzyme seals the space between the molecules to form a single DNA fragment.
The others enzymes have different functions:
DNA helicase is characterized by separating DNA from double strands into single strands and acts in DNA replication.
ATP methylase plays an important role in DNA replication when determining the beginning of replication that has already been replicated or not.
DNA polymerase is an enzyme that is responsible for catalyzing the polymerization of the new strand of DNA during the replication of this molecule.
Nucleic acids function is to make up genetic information in living things. There are two types of nucleic acid and they are DNA and RNA. DNA is the basic instructions for living things. It is passed down from parent to offspring and is found in the nucles of the cell
Answer:
50%
Explanation:
Both parent's genotype is Bb because they are hairless and alive.
If it has a homozygous dominant genotype (BB), the dog will die in utero.
If it has a heterozygous genotype (Bb), the dog will be hairless but won't die.
If it has a homozygous dominant genotype (bb), the dog will have hair.
The ratio of BB:Bb:bb is 1:2:1 meaning that there is a 50% probability of having a live hairless puppy.

Answer:
four
Explanation:
Carbon atoms have four electrons in their outer shell. So, it exhibits tetravalency & thus, a single carbon atom can form a maximum of four (4) bonds with other atoms
