A producer cannot make sugars in the absence of light, the correct option is A.
<h3>What are producers?</h3>
Producers, also known as autotrophs, are lifeforms that produce their own food.
They obtain energy from chemicals or the sun and transform it into usable energy in the form of sugar or food using water.
Plants and algae can produce their own food by harnessing solar energy. These organisms are referred to as producers because they generate their own food.
Thus, the correct option is A.

Answer:
During DNA replication each parental DNA strand serves as a template to a new complementary strand. DNA polymerase is the main enzyme responsible for this process, it catalyzes the addition of nucleotides to form the new DNA chain.
The complementary nature of the DNA strands, presents a difficulty for DNA replication: DNA polymerase catalyzes the polymerization of DNA only in the 5’ to3’ -in the leading DNA strand. Thus, the opposite DNA strand, the lagging strand, faced an obstacle that is solved by the Okazaki small fragments. The primase enzyme synthesizes small RNA fragments complementary to the lagging DNA strand. These RNA fragments serve as primers for the DNA polymerase. To remove this RNA primers and form a continuous complementary lagging strand, RNase H and DNAse ligase will further cut and join the DNA again.
DNA polymerase has a higher processivity than primase, if processivity is the average number of nucleotides that it is capable to continuously add to the template strand. Primase dissociates from the template often during DNA replication as it has to constantly add new RNA primers to the strand.
