What does gyrase do during DNA replication?
Explanation:
DNA gyrase is an VERY important bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA. Gyrase categorized to a class of enzymes known as topoisomerases that are involved in the control of topological transitions of DNA. The mechanism by which gyrase is able to influence the topological state of DNA molecules is of inherent interest from an enzymological standpoint. Much attention has been focused on DNA gyrase as the intracellular target of a number of antibacterial agents as a paradigm for other DNA topoisomerases. Current knowledge concerning DNA gyrase by addressing a wide range of aspects of the study of this enzyme. I hope this makes sense to you!

Will the hurricane gain strength or lose strength if it moves from warm water to cold water? Explain in 3-4 sentences
Answer:
Explanation:
As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow. More and more heat and water will be pumped into the air. The pressure at its core will drop further and further, sucking in wind at ever-increasing speeds. Over several hours to days, the storm will intensify, finally reaching hurricane status when the winds that swirl around it reach sustained speeds of 74 miles per hour or more.

Mendel crossed wrinkle-seeded (rr) plants with pure round-seeded plants (RR). What percentage of the resulting generation had wrinkled seeds?
Mendel crossed wrinkle-seeded (rr) plants with pure round-seeded plants (RR). 50% percentage of the resulting generation had wrinkled seeds.
What is Mendel's cross?Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation.
A dihybrid cross is a breeding experiment between two organisms which are identical hybrids for two traits. In other words, a dihybrid cross is a cross between two organisms, with both being heterozygous for two different traits.
For monohybrid cross, Mendel began with a pair of pea plants with two contrasting traits i.e., one tall and another dwarf. The cross-pollination of tall and dwarf plants resulted in tall plants. All the hybrid plants were tall.

A student attaches a rope to the handle of a chest loaded with a few books, while the other end of the rope is tied to a spring scale. The student pulls the scale with just enough force to set the chest in motion and records the force applied on the spring scale. The student repeats the experiment with more books in the chest and records the data in a table.
What can be concluded from the data?
As the mass of the chest increases, less force is required to pull it.
As the mass of the chest increases, less force is required to pull it.
As the mass of the chest increases, more force is required to pull it.
As the mass of the chest increases, more force is required to pull it.
The amount of frictional force increases as the mass of the chest decreases.
The amount of frictional force increases as the mass of the chest decreases.
The amount of frictional force decreases as the mass of the chest increases.
The amount of frictional force decreases as the mass of the chest increases.
Answer:
As the mass of the chest increases, more force is required to pull it.
Explanation:
Mass is a measure of the inertia of a body. Inertia means reluctance towards motion. A heavier object has a greater degree of inertia than a lighter object.
Hence, the student will notice that more force is required to move a heavier chest of books than a lighter one.
Therefore, as the mass of the chest increases, more force is required to pull it.

HOW DOES THE MEIOSIS PROCESS WORK ?
What is different between meiosis and mitosis?
Whats the different between haploid and diploid?
Answer:
Meiosis is broken down into several stages. Each cell in the process of meiosis involves the cell growing, dividing, splitting, and dividing again in order to produce the four cells at the end of the process. This cellular process is one of the more common processes of biology, but it is also the reason why people have some traits over others.
Explanation:
The difference between mitosis and meiosis is in the process by which each form daughter cells from a parent cell. Mitosis has one round of cellular division and genetic separation whereas meiosis has two rounds.
The key difference between haploid and diploid is that haploid is the state of having half the usual number of chromosomes while diploid is the state of having the usual number of chromosomes in the genome of a cell.

This stage of interphase occurs immediately after the cell divides 3. This stage of interphase is where the cell copies the DNA 4. The process directly after interphase that consists of four stages. This is where the nucleus divides and each cell contains a complete copy of the parental chromosomes. 5. Main stage of mitosis where the cell grows, carries out normal functions, and duplicates its DNA. 6. This stage takes place before mitosis and after synthesis of DNA
Answer:
1. Cytokinesis
2. G1
3. S
4. Mitosis
5. Interphase
6. G2
Explanation:
This question is describing the phases in the MITOTIC PROCESS. Mitotic process is grouped into Interphase and Mitosis. The Interphase involves stages such as G1 (first gap phase), S (synthesis phase) and G2 (second gap phase) while mitosis consists of prophase, metaphase, anaphase, and telophase.
1. The stage where the cell divides into 2 daughter cells with identical nuclei is called CYTOKINESIS
2. The G1 stage is the first stage of interphase which occurs immediately after the cell divides i.e. after cytokinesis
3. The SYNTHESIS or S stage of interphase is the stage where the cell copies its DNA i.e. duplicates its genetic material (DNA).
4. MITOSIS is the process directly after interphase that consists of four stages viz; prophase, metaphase, anaphase, and telophase. This is where the nucleus divides and each cell contains a complete copy of the parental chromosomes.
5. The INTERPHASE is the main stage of mitosis where the cell grows, carries out normal functions, and duplicates its DNA.
6. The SECOND GAP PHASE or G2 stage takes place before mitosis and after synthesis of DNA (S phase).
1. The stage where the cell divides into 2 daughter cells with identical nuclei is called:
Cytokinesis2. The stage of interphase which occurs immediately after the cell divides is known as:
G13. The stage of interphase is where the cell copies the DNA is known as:
Synthesis4. The process which directly occurs after interphase that consists of four stages. This is where the nucleus divides and each cell contains a complete copy of the parental chromosomes. This is called:
Mitosis5.The main stage of mitosis where the cell grows, carries out normal functions, and duplicates its DNA is known as:
