the only possibilities for the childrens genotypes are; A and AB, so the fact that the child has a blood type of O isn't possible
Answer:
monomers of MONOSACCHARIDES
Explanation:
Polysaccharides are large molecules formed from chains of POLYMERS linked together by glyosidic bonds. <u>MONOMERS are small sub units that formed polymers, they are therefore the building block of a polysaccharides. The monomers of polysaccharides are called monosaccharid</u>es (1 sugar molecule.) when two of these are joined together they formed disaccharides (two sugars.)
Polysaccharides are fromed by joining together condensation, (loss of water molecules,) of mutiple monosaccharides units and the reversal of this to add water molecules to sepate them to monosaccharies is sugar Hydrolysis.
Example of polysaccharides are starch, glycogen cellulose
Example of monosaccharides are glucose, galactose.
Disaccharides are common table sugar, sucrose, maltose, lactose
Answer:
Explanation:
If the disorder is recessive, neither parent has to have the disorder because
they can be heterozygous. The characteristic features of autosomal recessive inheritance is as follows:-
•Appears in both sexes with equal frequency
• Trait tend to skip generations
• Affected offspring are usually born to unaffected parents
• When both parents are heterozygous approx. 1/4 of the progeny will be affected
• Appears more frequently among the children of consanguineous marriages.
The given pedigree follows these features. So the correct option is 'Autosomal recessive trait'.
Please correct me If I am wrong :)
The greatest threats to coral reefs is the rising temperature of the oceans as a result of climate change and the acidification of the oceans due to increased levels of carbon dioxide in the atmosphere which dissolves in the ocean and forms carbonic acid.Aug 3, 2015
Elephants have multiple copies of the p53 genes that play an important role in the control of cell division.
<h3>What is the role of p53 genes in elephants?</h3>
P53 is an important regulator of the DNA repair processes and controls uncontrolled cell proliferation. When DNA is harmed, the protein becomes active and aids in orchestrating a response that stops DNA replication and fixes any incorrect copies of the cell. The oncogene MDM2 E3 ubiquitin ligase, another protein, is responsible for deactivating the p53 repair activity in duplicated cells with intact DNA since it is not required.
A human with only two alleles from a single gene has much fewer molecular anti-cancer interactions than an elephant, which has 40 alleles, or versions, from its twenty p53 genes. Although the elephant may appear to have excessive genetic diversity, each of its 40 alleles is structurally slightly different.
I understand the question you are looking for is this:
Compared to humans, elephants have a dramatically low instance of cancer. Elephants have multiple copies of the _____ genes that play an important role in the control of cell division.
