The answer is DNA joins another DNA molecule from Intermolecular Hydrogen Bonds. Adenine forms two Hydrogen bonds with Thymine.
Cytosine forms three Hydrogen bonds with Guanine.
At each attachment point within a polynucleotide, the 5' end of one nucleotide joins the 3' end of the adjacent nucleotide through a linkage called a phosphodiester bond (Figure 3). It is this alternating arrangement of sugars and phosphate that forms the "backbone" of a DNA molecule.
What is DNA replication?
Before a cell divides, its DNA replicates (duplicates). Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically provides the information needed to make its partner. When the two strands of a DNA molecule are separated, each can be used as a template to make a complementary strand. Each template and its new complement together form a new DNAdouble helix identical to the original one.
Before replication can take place, the length of the double helix of the DNA to be copied must be unwound. Also, the two strands must pull apart like the two sides of a zipper, breaking the weak hydrogen bonds that connect the paired bases. Once the DNA strands have unwound, they must be held apart to expose the bases so new nucleotides can form hydrogen bonds with them.
The enzyme DNA polymerase then moves along the exposed strand of DNA, joining the newly arrived nucleotides into a new strand of DNA that is complementary to the template.
Mitochondria is the site of cellular respiration which produces energy. A cell with few energy needs would therefore contain a small number of this organelle.
The symbol on a regulatory marker
that indicates hazards such as rocks or stumps is an Orange Diamond. Regulatory
markers are types of non-lateral markers such as white and orange markings that
are used as navigation aids that give directions, warn of dangers and marks
controlled locations. Orange diamond shapes warns of dangers such as rocks,
stumps or construction.
Almost all living creatures on our planet depend on plants for food and oxygen, either directly or indirectly. So, if all the plants disappeared, eventually so would almost all the other life. Also, Earth would be hotter.
The larger mass a star has the shorter its life span will be because since it is so large, the more nuclear energy it has to create to keep it up and running. So the smaller the star the longer its life span and vise versa. Hope this helped!
Considering the question is asking only for the percentage of the P allele, then the correct answer is A - 89 percent.
This is correct because we always have a combination of 2 alleles, either PP, Pp or pp. If from all these the p allele is found only in 11% then the remaining 89% are from the P allele.
