The importance of DNA copying in reproduction is Organisms look similar because their body designs are similar. If body designs are to be similar, the blueprints for these designs should be similar. Thus, reproduction at its most basic level will involve making copies of the blueprints of body design. The chromosomes in the nucleus of a cell contain information for inheritance of features from parents to next generation in the form of DNA (Deoxyribo Nucleic Acid) molecules. The DNA in the cell nucleus is the information source for making proteins. If the information is changed, different proteins will be made. Different proteins will eventually lead to altered body designs. Therefore, a basic event in reproduction is the creation of a DNA copy. Cells use chemical reactions to build copies of their DNA. Thiscreates two copies of the DNA in a reproducing cell, and they will need to be separated from each other. However, keeping one copy of DNA in the original cell and simply pushing the other one out would not work, because the copy pushed out would not have any organized cellular structure for maintaining life processes. Therefore, DNA copying is accompanied by the creation of an additional cellular apparatus, and then the DNA copies separate, each with its own cellular apparatus. Effectively, a cell divides to give rise to two cells.
These two cells are of course similar, but are they likely to be absolutely identical? The answer to this question will depend on how accurately the copying reactions involved occur. No bio-chemical reaction is absolutely reliable. Therefore, it is only to be expected that the process of copying the DNA will have some variations each time. As a result, the DNA copies generated will be similar, but may not be identical to the original. Some of these variations might be so drastic that the new DNA copy cannot work with the cellular apparatus it inherits. Such a newborn cell will simply die. On the other hand, there could still be many other variations in the DNA copies that would not lead to such a drastic outcome. Thus, the surviving cells are similar to, but subtly different from each other.

<span> sin(A)/a = sin(C)/c, so sin(A) = asin(C)/c = sin(35deg)/2. So A = arcsin(sin(35deg)/2) = 16.67. </span> The answer to your question is A. I hope that this is the answer that you were looking for and it has helped you.
Answer: <span>inorganic phosphate 3'-oh end of the new DNA strand; all four
deoxyribonucleotides triphosphates (containing a, c, t, or g) ; single-stranded dna template </span> <span>DNA polymerase will add free nucleotides only to the 3' end of the new strand but only if there is a pre-existing 3'-OH group. The enzyme DNA polymerase will form hydrogen bonds with the nucleotides of the template DNA and add new nucleotides, adenine will bond with thymine and
guanine will bond with cytosine. The replication process has produced
a new DNA molecule by using the original strand as a template and the
new strand formed which is identical</span>
In summary, breathing is the process of inhaling and exhaling through our lungs. It brings oxygen into the body and expels unwanted carbon dioxide. ... Our cells perform cellular respiration with oxygen and glucose to make energy and carbon dioxide.
