Predict the effects of the following types of gene mutations on the protein encoded by that gene (your answer can be just a few
o-na [289]

Answer:

Nonsense mutation: it causes a premature stop codon, so the protein cannot be fully synthesized.

Missense mutation: it causes change on the aminoacid encoded, so it can cause a change in the protein structure if the new aminoacid doesn't have the same chemichal properties as the original.

Synonymous (silent) mutation: it causes no change, the same aminoacid is encoded.

Single nucleotide insertion or deletion: changes the entire structure of the protein because it shifts the reading frame.

Three nucleotide deletion: one aminoacid will no longer be part of the protein, if this aminoacid was located, for example, on the active site of an enzyme, the protein could lose its function.

Chromosomal translocation: it can break a gene in two, causing the protein to no longer be able to be synthesized, or it can change the transcription regulation because it is now under the effect of other regulating sites that result in a different transcription pattern.

What type of barrier is the cell membrane?; How does the cell membrane act as a barrier?; What part of the cell forms a barrier
vichka [17]

A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The cell membrane regulates the flow of substances into and out of the cell.

The cell membrane, commonly referred to as the plasma membrane, serves as the body of a cell. It also keeps the environment inside the cell constant, and that membrane has many functions. One is to introduce nutrients into the cell while removing toxic chemicals from it. Another is that the cell's plasma membrane, which is its outer membrane, will have proteins that interact with other cells. These proteins may be glycoproteins, which also contain a sugar moiety, or lipid proteins, which contain both a protein and a fatty acid. Proteins that stick outside of the plasma membrane also allow for cell-to-cell communication. The cell membrane also provides some structural support.
