Answer:
This disorder is caused by mutations in either of two different genes; one of these genes is linked to the DNA marker locus and the other gene is not.
Explanation:
A gene marker (also known as a molecular marker) is defined as a particular DNA sequence that has a specific physical location on a given chromosome. The gene markers are always physically linked with genes of interest, thereby they are useful for identifying patients affected by a given disease and/or a particular phenotypic trait. In this case, in the first study, genetic variation of the marker has been shown to be useful to map one <em>locus</em> that is associated with the disease phenotype. However, in the second study, a second <em>locus</em> that is not linked to the marker can segregate independently, thereby showing different results from the first study (in this case, it is imperative to develop a new genetic linkage analysis to discover genetic markers linked to the second gene, which is also responsible for the disease phenotype).
Answer:
Satellites orbit earth because of gravity
Answer:
Using the number of amino acid differences, it would appear that the two birds are more closely related (had a common ancestor very recently), while the two fungi would have to trace their common ancestry much farther back in time (much more distantly related).
Answer:
Through glycosidic bond.
Explanation:
Disaccharide:
Disaccharide is simple polysaccharide. It is formed when two monosaccharides combine together. The monosaccharides are combine through dehydration reaction as a result glycosidic bond is formed between two monosccharides with removal of water molecule.
The reaction is also called condensation reaction.
There are two types of disaccharides:
Reducing disaccharides
These are hemiacetal and have reactive carbonyl group. They can be oxidized to other products.
Non - reducing disaccharides
These are acetals and can not be easily oxidized like reducing disaccharides.
Glycosidic bond:
It is covalent bond formed between the carbohydrate and another molecule such as monosaccharide.
This bond can be alpha or beta glycosidic bond.
