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.
Steroids
are complex structure four connected rings of carbon atoms. They are cholesterol which is in all body cells and used to synthesize other steroids:sex hormones, such as estrogen, and testosterone and several hormones from the adrenal glands.
Waxes
are comprised of an ester of a long-chain alcohol and a fatty acid. Many plants have leaves and fruits with wax coatings to help prevent water loss.
Phospholipids
consist of Glycerol portion and fatty acid chains. Only two fatty acids chains; in place of the third is portion that include a phosphate group. THe phosphate portion is soluble in water [hydrophobic] forms the ''head'' of the molecule, while the fatty acids portion is insoluble in water [hydrophobic] and forms a ''tail''.
Fats
to store energy for cellular activities. Carbohydrates fat molecules are composed of carbon, hydrogen and oxygen atoms.
Answer:
Chlorophyll-to trap enough light for photosynthesis
The answer that describes the sentence above in which is a segment of DNA that are being coded in means of making one type of protein molecule is known as the gene. The gene is considered to be a unit that is physical and function responsible for heredity.
