Linker DNA links adjacent nucleosome core particles to each other. They then resemble beads on a string. These linker DNAs are readily removed through exonuclease hydrolysis.

What is a fusion primer?

Not 100% sure, but I believe it's a primer with a linker attached to it. A linker is a short DNA that has a restriction site built-in. Imagine this: you want to amplify a gene by PCR, but it has no suitable restriction site for you to clone into a vector. So by PCR with a fusion primer (with built-in restriction site), you can simply digest the ends and ligate it into your vector


What is cross-linker solution?

A cross-linker solution is a chemical compound used in cross-linking reactions to form covalent bonds between molecules or polymers. This helps to stabilize or enhance the structure of materials like gels, adhesives, or coatings. Cross-linkers are commonly used in biology, chemistry, and materials science.


Which cell junction has a linker proteins spanning the intracellular space?

Desmosomes have linker proteins known as desmoplakins that span the intracellular space and help to connect intermediate filaments. Desmosomes provide strong adhesion between adjacent cells, especially in tissues that experience mechanical stress, such as the skin and heart muscle.


What is the function of DNA helicare in DNA replication?

DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.


Which cell juction has a linker proteins spanning the intercellular space?

Tight junctions have linker proteins that span the intercellular space, specifically claudins and occludins, which create a barrier between adjacent cells. These proteins help maintain cell polarity and regulate the passage of substances between the cells. By sealing the space between cells, tight junctions play a crucial role in controlling the permeability of epithelial tissues.
