The correct matching of enzymes and their role in the process of DNA replication is A- 3, B- 5, C-1, D-2 and E-4.
Replication is the process of synthesis of two indentical copies of DNA from a single DNA molecule. It is catalyzed by a set of enzymes with the following function-
A. RNA primase synthesizes an RNA primer (short sequence of RNA) on the lagging strand complementary to the single stranded DNA which acts as template during DNA replication.
B. Ligase is involved in joining the okazaki fragments on the lagging strand together and sealing the nicks of the DNA strand.
C. Helicase separates the two DNA strands at the replication fork.
D. Polymerase synthesizes the complementary daughter strand by adding nucleotides to DNA.
E. Topoisomerase relaxes the highly coiled DNA by creating nick ahead of the replication fork in the phosphate backbone of DNA strands.
Answer:
The given blank can be filled with location of gene expression.
Explanation:
A regulatory sequence refers to a section of a molecule of nucleic acid that possesses the tendency of declining or upsurging the expression of particular genes within an organism. The regulation of gene expression is an important characteristic of all living species and viruses.
In the given case, it is essential to use the regulatory sequence of a milk gene when developing a recombinant gene as a regulatory sequence monitors the location of gene expression.
Answer: you can recognize a plant cell by its rigid cell wall and by the fact that it contains fluid filled space known as a vacuole.

Answer:
The correct answer is multicellular organisms.
Explanation:
Organs are differentiated structure formed by group of cells and tissues to perform the similar functions. When more than two organs perform specific function in a coordinated manner they form organ system.
Tissues and organs are a characteristic feature of multicellular organisms as more than one cell is present in these organisms and these cells aggregate together to form tissues, which further aggregate to form different organs carrying out the different functions attaining complexity.
Since, unicellular organisms do not have more than one cell, unicellular cells do not form tissues and lack organs.
Thus, the correct answer is multicellular organisms.
which is absent in unicellular organisms.
