Is the orbits of the planets lie in nearly the same plane and they all revolve around the sun in the same direction a fact or inference?
Inference.
In light of modern solar system theory why do the orbits of the planets all lie in nearly the same plane?
The orbits of the planets lie in nearly the same plane because they formed from a rotating disk of gas and dust around the young Sun, known as the solar nebula. As gravity caused material in the disk to clump together, it formed into the planets we see today, all orbiting in a flat plane due to the conservation of angular momentum.
The nearly perfect spherical shape of the moon is an indication that it is spinning very rapidly?
Actually, the nearly perfect spherical shape of the moon is more attributed to its own gravity pulling it into a round shape, rather than its rotation speed. The moon's rotation is tidally locked with Earth, so it rotates at the same rate it orbits, which is why we always see the same side of the moon facing us.
What aspects of the planets orbits are nearly the same for most planets?
1. Planets in the orbits all conform to Kepler's three laws of planetary motion, 2. The orbits are all nearly in the same plane,3. The orbits are all elliptical, but not very ellptical and near-circular in shape, with the Sun slightly off-centre.Added:p2 = a3P. The planetary orbital period in earth years.a. Distance from sun in astronomical units, based on 1 AU for earth. ( for example, Mars would be about 1.5 AU and you would use this value in the equation, not the actual distance )
Roughly the same size as Earth?
Earth is about 12,742 kilometers in diameter, so objects that are roughly the same size could have diameters within that range. Examples include Venus, Mars, and the Earth's moon, which all have diameters that are relatively close to that of Earth.
Who has exactly the same DNA restriction fragments?
two identical DNA fragments will have identical restriction fragments. Also, genetically identical twins will have identical restriction fragments
Does a restriction enzyme generate the same size fragments in genomic DNA of different species?
No, restriction enzymes do not always generate the same size fragments in genomic DNA of different species. The specific DNA sequences recognized by the enzyme and the distribution of those sequences in the genome will determine the size and distribution of the fragments produced. Differences in genome size, organization, and sequence between species will result in variation in fragment sizes.
Why might different alleles of the same gene produce different fragments when treated with the same restriction enzyme?
Well..... It is quite simple. if you take the square of the number of alleles and then times that by the smaller of the height of the triangle you should get your answer.
Two small restriction fragments of nearly the same base pair size appear as a single band even when the sample is run to the very end of the gel What could be done to resolve the fragments?
To resolve the two fragments, you can increase the percentage of the gel or run the gel for a longer period of time to improve separation based on size differences. Additionally, you may consider using a different type of gel (e.g., higher resolution gel) or using a different buffer system to enhance resolution.
What is Example of restriction enzyme?
A restriction enzyme (also known as restriction endonuclease) is protein which cuts DNA up at specific sequences (called restriction sites) in a genome. For example, the commonly used restriction endonuclease EcoRI recognizes every DNA sequence GAATTC and cuts at the point between the guanine and the adenine in that sequence, forming blunt ends (or straight, even ends). Interestingly and coincidentially, the restriction site for most restriction enzymes are genetic palindromes (the sequence reads exactly the same backwards on the complementary strand). In the case of EcoRI, the two complementary DNA strands for the restriction site are:5'-- GAATTC --3'3'-- CTTAAG --5'After this DNA sequence is cut, it might look something like this:5'-- G AATTC --3'3'-- C TTAAG --5'
DNA strands can be clipped crosswise at selected positions by using enzymes called?
DNA can be cut into smaller fragments by enzymes (which are proteins) known as restriction endonucleases (REN's). These enzymes are sequence specific - meaning they produce a cut only at a particular site on the DNA strand. This site where the cut is produced is called the restriction site. Restriction sites are 4 - 6 nucleotides in length. Every restriction enzyme has a different restriction site. This property allows researchers to treat two different DNA samples with the same set of restriction enzymes and then analyze the resulting fragments.A. DNA finger printing
The rate at which large DNA fragments move through the electrophoretic gel is?
The rate at which large DNA fragments move through the electrophoretic gel is slower compared to small DNA fragments because larger fragments experience more resistance as they navigate through the gel matrix. This results in larger DNA fragments being located closer to the well where they were loaded onto the gel, while smaller fragments move further down the gel towards the positive electrode.
How do different restriction enzymes produce different DNA fragments from the DNA molecule?
DNA from two different people may have different sequences in the non-coding regions of their DNA. These differences may result in one person having a particular restriction site and the other person not having it. Different numbers and types of restriction sites will cause different fragments to be produced.
Is gravel and conductor means the same?
No, gravel and conductor are not the same. Gravel is a loose aggregation of small rock fragments, while a conductor is a material that allows the flow of electricity.
Why is it important to use the same restriction enzyme for both cells in recombinant DNA?
Restriction enzymes are endonucleases that digest the DNA at a sequence specific site. Hind III for example cut between two As in the sequence AAGCTT in the both strand forming a sticky end. If you use this enzyme to cut in your vector DNA, you have to use the same enzyme in the insert DNA so as they can ligate by DNA ligation. This is the important use of same restriction enzyme in cloning.
How is transformation used to construct recombinant DNA molecules?
DNA fragments have to be cut precisely and then joined with the other fragment by using a ligase.To begin with, the DNA fragments to be joined should be cut with the same restriction enzyme or should have compatibility to join. Restriction enzymes make cuts at specific recognition sites. Hence restriction digestion with same enzyme for two different DNA fragments yields identical ends.Two DNA fragments with protruding ends complementary to each other are joined using a Ligase and blunt ended DNA fragments are joined by means of adding additional complementary sequences at their ends with the help of linkers, adapters or by using a terminal transferase for Homopolymer Tailing.
Why did you cut both segments of DNA with the same restriction enzyme?
You use the same enzyme inn order to get the same restriction and binding sites.
