Answer:

Yes. the Integral membrane will be affected.

Explanation:

Generally, Ionic detergents have hydrophilic head group which can be either negatively charged or positively charged. If treated with plasma membrane, it masks the native charge of the protein, colonizing the entire charges of the protein, converting the overall charge  to its own.

To be specific SSD  is anionic. It therefore adds overall negative  charge(anion) to the entire protein charges, even if they have isoelectric points. ''<em>just like the HIV-RNA genome which  undergo retro-transcription of  the entire human DNA genome to its own HIV- genome of the infected host!''.</em>

This disrupts  the hydrogen bonds, hydrophobic interactions and other non-covalent bonds of protein , thus  the 3-Dimensional protein structure of tertiary protein and therefore of the integral membrane proteins . Denaturation of  protein structure, and therefore the conformation protein function  results.With resulting   separation of the protein molecules based on their sizes.

A calico cat has both black and orange spots, which demonstrates a codominance pattern. What would be their expected genotype?
Oksi-84 [34.3K]

Answer:

Calico is a coat color found in cats, which is caused by a SEX-LINKED, CODOMINANT allele.

Explanation:

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
