Explanation:
How would you convert a spring into a straight piece of metal using the same approach as topoisomerase in DNA replication?
Answer:
It would be necessary to make small breaks in the spring and then align the pieces, forming a straight piece.
Explanation:
Topoisomerase is the enzyme responsible for unwinding the DNA molecule during replication. To do this, topoisomerase makes small breaks in the DNA molecule, but uses covalent bonds to hold these small pieces of DNA, causing the strands of DNA to pass over each other, aligning in a rectilinear topography.

A cell's mRNA loses all of its uracil. What will happen next?
If a cell's mRNA loses all of its uracils, then it will not undergo a protein synthesis or translation process.
as defected mRNA will not be able to form all anticodon thus there is no codon formation takes place for protein synthesis.
What are codon and anticodon?Codon: A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid.
Anticodon: An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence.
Hence, If a cell's mRNA loses all of its uracils, then it will not undergo a protein synthesis or translation process.

17. Identify How would the
shuttle's motion change if
there were no gravitational
force between it and Earth?
Answer:
Gravity is one of those things we take completely for granted. And there are two things about it that we take for granted: the fact that it is always there, and the fact that it never changes. If the Earth's gravity were ever to change significantly, it would have a huge effect on nearly everything because so many things are designed around the current state of gravity. Before looking at changes in gravity, however, it is helpful to first understand what gravity is. Gravity is an attractive force between any two atoms. Let's say you take two golf balls and place them on a table. There will be an incredibly slight gravitational attraction between the atoms in those two golf balls. If you use two massive pieces of lead and some amazingly precise instruments, you can actually measure an infinitesimal attraction between them. It is only when you get a gigantic number of atoms together, as in the case of the planet Earth, that the force of gravitational attraction is significant. The reason why gravity on Earth never changes is that the mass of the Earth never changes. The only way to suddenly change the gravity on Earth would be to change the mass of the planet. A change in mass great enough to result in a change in gravity isn't going to happen anytime soon.
Explanation:
But let's ignore the physics and imagine that, one day, the planet's gravity turned off, and suddenly there was no force of gravity on planet Earth. This would turn out to be a pretty bad day. We depend on gravity to hold so many things down -- cars, people, furniture, pencils and papers on your desk, and so on. Everything not stuck in place would suddenly have no reason to stay down, it would start floating. But it's not just furniture and the like that would start to float. Two of the more important things held on the ground by gravity are the atmosphere and the water in the oceans, lakes, and rivers. Without gravity, the air in the atmosphere has no reason to hang around, and it would immediately leap into space. This is the problem the moon has -- the moon doesn't have enough gravity to keep an atmosphere around it, so it's in a near-vacuum. Without an atmosphere, any living thing would die immediately and anything liquid would boil away into space. In other words, no one would last long if the planet didn't have gravity. If gravity were to suddenly double, It would be almost as bad, because everything would be twice as heavy. There would be big problems with anything structural. Houses, bridges, skyscrapers, table legs, support columns, and so on are all sized for normal gravity. Most structures would collapse fairly quickly if you doubled the load on them. Trees and plants would have problems. Power lines would have problems. The air pressure would double and that would have a big effect on the weather. What this answer shows you is just how integral gravity is to our world. We can’t live without it, and we can't afford to have it change. It is one of the true constants in our lives!

25 Zoogeographic regions are characterized by the presence of specific groups of animals. These
regions are determined by the taxonomic or phylogenetic relationships of animals. The map
shows the zoogeographic regions proposed by the naturalist Alfred Russel Wallace in 1876.
Zoogeographic Regions
Nearctic
Palearctic
Ethiopian
KEY
Neotropical
Geographical barriers
such as mountains or
bodies of water
Australasian
The similarities of organisms in which two areas numbered above provide the best evidence
for common ancestry between the organisms in both locations?
Aim
When dividing the world into zoogeographical regions, Alfred Russel Wallace stipulated a set of criteria by which regions should be determined, foremost the use of generic rather than species distributions. Yet, recent updates of Wallace's scheme have not followed his reasoning, probably explaining in part the discrepancies found. Using a recently developed quantitative method, we evaluated the world's zoogeographical regions following his criteria as closely as possible.
Location
Global.
Methods
We subjected presence–absence data from range maps of birds, mammals and amphibians to an innovative clustering algorithm, affinity propagation. We used genera as our taxonomic rank, although species and familial ranks were also assessed, to evaluate how divergence from Wallace's criteria influences the results. We also accepted Wallace's argument that bats and migratory birds should be excluded (although he was contradictory about the birds) and devised a procedure to determine the optimal number of regions to eliminate subjectivity in delimiting the number of regions.
Results
Regions attained using genera (eight for mammals and birds and six for amphibians) strongly coincided with the regions proposed by Wallace. The regions for amphibians were nearly identical to Wallace's scheme, whereas we obtained two new ‘regions’ for mammals and two for birds that largely coincide with Wallace's subregions. As argued by Wallace, there are strong reasons not to consider these as being equivalent to the six main regions. Species distributions generated many small regions related to contemporary climate and vegetation patterns, whereas at the familial rank regions were very broad. The differences between our generic maps and Wallace's all involve areas which he identified as being uncertain in his regionalization.
Main conclusions
Despite more than 135 years of additional knowledge of distributions, the shuffling of generic concepts, and the development of computers and complex analytical techniques, Wallace's zoogeographical regions appear to be no less valid than they were when he proposed them. Recent studies re‐evaluating Wallace's scheme should not be considered updates as such because they have not followed Wallace's reasoning, and all computer‐based analyses, including this one, are subject to the vagaries of the particular methods used.

How are alleles represented in genetics?
Biologists refer to dominant alleles as uppercase letters and recessive alleles as lowercase letters when referring to genotype.
What are alleles?Genetics and evolution define an allele as a variant of the same sequence of nucleotides at the same location on a lengthy DNA molecule.
The variant DNA sequences at a locus are known as alleles, and the chromosomal or genomic location of a gene or any other genetic element is referred to as a locus.
Alleles can be identified using just one capital or lowercase letter, two, three, or more letters, or letter/number combinations. Superscripts, subscripts, or both may be present in alleles.
Alleles that are recessive are denoted by lowercase letters, while dominant alleles are denoted by capital letters.
Thus, this way, the alleles are represented.

No tienen cloroplastos
No tienen organelas
El ADN no está asociado a proteínas
El ADN es circular
Presenta mesosomas
Explanation:
Las células procariotas son más primitivas que las eucariotas, por ende, sus estructuras son más simples. Las células procariotas están en organismos unicelulares tales como las bacterias, mientras que las células eucariotas están en organismos unicelulares y pluricelulares como en plantas, animales, u hongos. La diferencia más notoria entre ambos tipos de células es la ausencia de núcleo en las procariotas haciendo que el ADN está disperso en el citoplasma mientras que en las células eucariotas, el ADN está dentro del núcleo celular.
