An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you use a reference point. If an object's distance from another object [reference point] is changing. A place or object used for comparison to determine if something is in motion.
I'm not too sure if this is what you needed go know, I hope it helped
Answer:
Rapidly and Accurately
Explanation:
As an example, eukaryotic human DNA replicates at a rate of 50 nucleotides per second.
Replication occurs so quickly because multiple polymerases<em>, or think: enzyme+polymer=polymerase,</em> can synthesize<em>, or combine or fuse,</em> two new strands at the same time by using each untwined strand from the original DNA double helix as a guide.
DNA replication is so much faster than bacteria replication because it's extremely difficult to replicate DNA accurately, as well as copying molecules that tightly complexed with histones in nucleosomes, which work together to form chromatin, which is the material that chromosomes are composed of, and it's further composed of protein (histones), DNA, and RNA.
Therefore, the reason for human cells taking significantly less time to replicate its genome is <u>accuracy</u>.
Answer:
The correct answer is option C. "arg+leu– or arg–leu+".
Explanation:
This bacteria is not able to growth on minimal medium or minimal medium supplemented with leucine. This means that the bacteria needs external supplementation of amino acids to growth, either arginine or leucine. Therefore, this bacteria can have the genotypes of arg+leu– or arg–leu+, meaning that the bacteria is able to synthesize either of two amino acids, but not both, because if that was the case the bacteria would be able to growth on minimal medium.
