ocean trenches are most often formed when

Answers

Ocean trenches are deep sections of the ocean where an oceanic plate is usually sinking below a continental plate. How are they formed? They are formed in the subduction zone as the denser oceanic plate is subjected under the continental plate.

Answer:Ocean trenches are driven by tectonics and are most commonly found along the Pacific Ocean in a zone known as the ring of fire. They are usually formed at the boundaries of convergent plates, at a region where a continental plate submerges beneath an oceanic plate.

PLEASE HELP!!!? Are humans an invasive species? Why or why not. GIVE TWO PIECES OF EVIDENCE TO SUPPORT YOUR OPINION.

Answers

Answer:

I think yes, humans are an invasive species.

Explantation:

I think humans are an invasive species because they are everywhere, and very few places in the world do not have humans. Humans are in control of the planet because of their number. Humans are not going to be extinct ever. They are always going to be here on earth. If somebody finds new land, they make a base/camp and send other people to live there and to populate it. Like in North america, settlers came and sent men to live there. They hunted animals and set up homes. Then, more and more people came and soon all that is left is a over populated land with citys and cars and humans everywhere.

I hope this helps. :)

Cell biologists studying the mobility of plasma membrane proteins fused mouse and human cells together, creating a heterokaryon. They then examined the localization of mouse and human proteins over time. Initially the mouse and human proteins were restricted to separate halves of the heterokaryon. Over time the mouse and human proteins mixed, with each protein eventually being present over the entire cell surface, consistent with proteins being able to move within the plane of the membrane. What techniques could have been used to examine the locations of the mouse and human membrane proteins

Answers

Answer: Fluorescence microscopy

Explanation:

A protein is substance that is the essential constituent of living cells because it forms part of its structure. They are also found in plasma membrane, where they assist substances to cross the membrane. Proteins can be:

Integral: permanently attached within the plasma membrane.Transmembrane: it spans the entirety of the cell membrane.Peripheral: are only temporarily associated to the membrane.

Some integral proteins can act as cellular receptors. Other proteins are responsible for cell adhesion (binding of a cell to another cell or to a surface). On the outside of the cell membranes, attached to other proteins, are the carbohydrate chains that act as labels identifying the type of cell.

A heterokaryon is a multinucleate cell and in this experiment the scientists fuse a human cell and a mouse cell, each of them will have their own proteins. At first, the human and mouse proteins where found in separated halves of this heterokaryon. But after a while, those proteins where mixed and could no longer be identified.

A fluorescent chemical called a fluorophore is able to be absorb light of specific wavelengths and then emit light of longer wavelengths. The proteins can be modified and marked with different colored fluorophores to detect them, even if they are mixed in the heterokaryon. Then, they can be seen with a Fluorescence microscopy, to identify them through different colors.

Which statement best describes what happens during translation?

Answers

Answer:

Explanation:

The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.

During translation, the ribosome reads the mRNA and uses the information to assemble a protein.

Translation is the second step of protein synthesis. It takes place in the ribosome, a complex structure made up of proteins and RNA. The ribosome reads the mRNA, a molecule that contains the genetic information for a protein. The mRNA is translated into a protein by a process called codon-anticodon pairing.

Codons are three-base sequences in mRNA that code for specific amino acids. Anticodons are complementary sequences in tRNA molecules that bind to specific codons. When the ribosome encounters a codon in the mRNA, it brings in the corresponding tRNA molecule. The tRNA molecule carries the amino acid that corresponds to the codon.

The amino acid is then added to the growing polypeptide chain. The ribosome continues to move down the mRNA, reading codons and adding amino acids until the entire protein is synthesized.

What are three methods for detecting radioactively labeled DNA in an experiment?

Answers

Answer:

Limitations. detect low abundance DNA binding proteins from lysates. test binding site mutations using many probe configurations with the same lysate. test binding affinity through DNA probe mutational analysis. non-radioactive EMSA possible using biotinylated or fluorescently labeled DNA probes.

Explanation:

Answer:

Proteins interact with DNA through electrostatic interactions (salt bridges), dipolar interactions (hydrogen bonding, H-bonds), entropic effects (hydrophobic interactions) and dispersion forces (base stacking). These forces contribute in varying degrees to proteins binding in a sequence-specific or non–sequence-specific manner.
