    What is the full form of DNA?
    DNA is the abbreviation for DeoxyriboNucleic acids. DNA usually takes active roles during human formation because it contains genetic information that can be passed from one generation to another. The reason why some traits in your family which were very visible in the older generations are still being noticed in the present generation is due to DNA because it acts in such a way that it replicates copies of itself. It does this by forming a new strand so that each new cell can have the genetic composition of the old cell. Since DNA can be found in the nucleus of each cell, it helps in regulating and coordinating the metabolic process of the cell and the development of organisms. Genetic information is stored as codes through the four bases in DNA, the codes are Guanine, Thymine, Cytosine, Adenine. They ensure that hereditary materials are passed from parents to their children

  • Why do identical twins have different fingerprints?
    Why do identical twins have different fingerprints?
    It is true that identical twins form from one egg. They share some similarities when it comes to their DNA but fingerprints cannot be considered entirely as a genetic characteristic. This means that there are different factors that may affect the formation of any person’s fingerprints. The identical twins may develop their fingerprints while they are in their mother’s womb. Their positions and movements may change the type of fingerprints that they will form. Some identical twins have very similar fingerprints but they are not exactly the same. The hormone levels of identical twins may also have an effect on the formation of fingerprints as well as moles and freckles.

  • What will most likely be the effect of the change in the DNA molecule?
    What will most likely be the effect of the change in the DNA molecule?
    I think that the DNA will code for a different protein. Because if you switch up one of the Nitrogen bases of the codon it will most likely make a different type of protein.

  • What is the difference between Enhancer and Promoter?
    What is the difference between Enhancer and Promoter?
    Enhancers and promoters are associated with genes. If you are near the transcriptional start site, then you will probably find the promoter. However, genes have enhancers throughout them. With the gene expression, enhancers will enhance them. That is why they are named the enhancers. Promoters, on the other hand, will start the gene expression, which is why it is named the promoters. The effect of the positions of the enhancers and promoters are different. The enhancers position is independent, whereas the position of the promoter is dependent. Promoters conduct their work in the same transcriptional orientation, but the enhancer can work in the same or opposite orientation. It will work either way. Both the enhance and the promoter can be defined as specific sequences in DNA.

  • What will most likely be the effect of the change in the DNA molecule?
    What will most likely be the effect of the change in the DNA molecule?
    The answer is D.) The DNA molecule will code for a different protein. The severity of the effect will be different depending on the mutation. An example is a missense mutation, it is when the cause of a substitute is a same amino acid. The function and structure of the protein are less severe. But if the substituted amino acid is different from the original, it can cause a more severe effect on the protein’s function and structure. The effect on the organism of this change in the DNA differs that might have no effect or can be harmful to the organism. But whenever there is a change in the DNA molecule, it will always code for a different protein to sustain the DNA.

    Actually, I'd consider this to be anaphase (if we don't count prometaphase). Interphase is definitely not part of the mitotic phases if you consult the cell cycle.Great quiz!

    Which precursor molecule would serve as the substrate that formed the first nucleotide in segment E if adenine is the first base on thee template strand corresponding to the initiation point for...
    This picture shows a replication fork with leading and lagging strands, making this DNA replication, not RNA transcription. So, the base would be dTTP, not UTP, since this is DNA not RNA.

    Which strand of the DNA is the coding strand, serving as a template for mRNA synthesis? You have obtained a sample of DNA, and you transcribe mRNA from this DNA and purify it. You then separate the...
    The correct answer is option B From the image above, we can tell that the coding strand of DNA that serves as the template strand for mRNA synthesis is DNA strand 2. Looking at the ratio of complementary nucleotides that bind to each other are similar to that of DNA strand 2. Take for instance, the bond between A and T (the A in mRNA is complementary to that of T in DNA strand 2). Same as the U in mRNA is complementary to A in strand 2 of DNA. Also, G to C on both strands are complementary.

    It is common for dialysis bags or dialysis tubing to be used to allow for smooth flowing of molecules when dealing with a fluid. These bags are usually measured to make sure that the patient has enough in the bag to accomplish the goal at hand. If there were five dialysis bags constructed from a semi-permeable membrane that is impermeable to sucrose, they may be filled with various concentrations of the sucrose. Then each of these bags was place in separate beakers containing an initial concentration of 0.6 M of a sucrose solution. At ten minute intervals, the bags were massed and weighed to see the change in the percent of concentration. In this case, the bag with the lowest initial concentration of sucrose would be the one whose mass decreases over time.
