Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the
serg [7]

Scientists have found that extracellular matrix component may induce specific gene expression in the embryonic tissues such as the liver and testes. For this to happen, there must be a direct communication between the extracellular matrix and the developing cells. The Integrins of transmembrane protein would most likely be involved in this kind of induction.

Integrins are the main principal receptors used by the cells of  animal to bind to the matrix of extracellular. They are heterodimers and they function as transmembrane linkers between the actin cytoskeleton and the extracellular matrix. A cell can regulate the sticky activity of its integrins from within.

True or false: in the sequence aggcct, an available phosphate group would be found at the 5' end of the nucleotide labeled "t."
Oksanka [162]

The answer is false.

an available phosphate group would be found at the 5' end of the nucleotide labeled A. The 5′-end of a DNA contains a phosphate group that is  attached to the 5′ carbon of the ribose ring and that A phosphate group  permits ligation of two nucleotides ( phosphodiester bond).
