Answer:
Polygenic inheritance is determined by multiple Genes located at different loci on different chromosomes.
Polygenic inheritance happens when an individual posses quantitative traits that become a variation compared to the parent's traits.
This phenomenon happens due to the combination of two or more genes that resulted in the characteristics that considered as the combination of both parents' characteristic.
Explanation:
Answer:
A. Phospholids and B. Steroids.
Explanation:
Lipids are fatty waxy molecules which are smaller than proteins that completes a lot of basic structures in both animals and plants inclusive.
They are been used by the body alongside proteins, sugars, and minerals. They can be found in many parts of a human: cell membranes, cholesterol, blood cells, and in the brain, to name a few ways the body uses them. The commonest of lipids are the steroid lipids which are seen in female oestrogen and in the male testosterone.
As discussed in Chapter 3, DNA replication is a semiconservative process in which each parental strand serves as a template for the synthesis of a new complementary daughter strand. The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain. However, DNA replication is much more complex than a single enzymatic reaction. Other proteins are involved, and proofreading mechanisms are required to ensure that the accuracy of replication is compatible with the low frequency of errors that is needed for cell reproduction. Additional proteins and specific DNA sequences are also needed both to initiate replication and to copy the ends of eukaryotic chromosomes.
Answer:50% chance possible offspring
Explanation:
Answer:
Eukaryotes have multiple replication forks, histones. Eukaryote have more Deoxyribonucleic acids in their genome compared to prokaryotic cells (e.g bacteria)
Explanation:
Bacteria is an example of prokaryotic cell. The difference between Eukaryotic cells and Prokaryotic cells is that prokaryotic cells are simple in structure, they have no nucleus, no organelles and a small amount of DNA in the form of a single, circular chromosome. While Eukaryotic cells have a well defined nucleus, multiple organelles and more DNA arranged in multiple, linear chromosomes
DNA synthesis is therefore more complex in eukaryotes because eukaryotes have multiple replication forks in which when replication occurs, precautions need to be set in place in order to prevent unwinding of the DNA strand in multiple sites in a single replication cycle. Also, the DNA in eukaryotes is packaged around histones to form chromatin. Before replication can occur, DNA needs to first be unwound around histones.
Eukaryotic DNA polymerase incoperates DNA at a much slower rate (17 nucleotides per second) than prokaryotic polymerase (1000 nucleotides per second). Therefore the eukaryotic cells are equipped with a slower polymerase but numerous replication forks more than just the two that are found in prokaryotic cells in order to effectively replicate the increased amount of DNA.
