The correct answer is:
nucleic acids
Explanation:
Nucleic acids are biopolymers, or humble biomolecules, necessary for all known methods of life. They are formed of nucleotides, which are monomers comprised of three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base..Nucleic acids are the basic unit of heritage, they develop all the genetic element of living things.This genetic information defines how individual cells and entire organisms grow and function
Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.
Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
Glycogen is also called as the animal starch. This carbohydrate polymer is made up of the several repeating monomer units (in thousands) of alpha D glucose. The skeletal muscles break down this glycogen into the monomer alpha D glucose units in order to generate energy, which can be used for the contraction and relaxation of the muscle filaments.
Hence, the answer is 'alpha D glucose'.
