Correct answer: Option D- DNA ligase
Explanation: In option A, thymine is a nucleotide, so it is present throughout the replication process, wherever it is required. It is added to the newly formed DNA. In option B, Helicase enzyme is active during initiation and elongation stage, as it facilitates the opening of the winded DNA strands. Option C is nucleotidase and it has no role in DNA replication. So, the correct answer is DNA ligase, which is option D.
The okazaki fragments formed during DNA replication are sealed at the end. And in this step, DNA ligase is used. It catalyzes the formation of phosphodiester bond between the nucleotides of okazaki fragments. So it is the last active molecule of the process.
Matrix are within the inner membrane of the mitochondria.
Answer:food undergo a chemical reaction by bond breaking example for starch to amylose is hydrolysis reaction where there is breaking of 1,4 glycosidic bondd
Cohesion is the property of like molecules to stick to each when they have a mutual attraction
Adhesion is the property of different molecules or surfaces to stick to each other
The correct answer is this one: "A.When actin filaments are pulled toward the center of the sarcomere, the fiber shortens." The statement that accurately describes the way in which a muscle moves is when actin filaments are pulled toward the center of the sarcomere, the <span>fiber shortens</span>
