What is the function of mRNA in the diagram above?

Undifferentiated cells in a tissue that can become specialized cells of that tissue, but not of other tissues, are __________ ce

lara31 [8.8K]

The answer is stem cells, they consist of classes of cells that are undifferentiated and are able to be classified them into types like specialized cells. They consist of having two main sources that will help them develop and mature, these main sources are called the embryonic stem cell and the adult stem cell.

sashaice [31]

Answer:

Golgi apparatus and extracellular matrix

Explanation:

The Golgi complex lies at the heart of the secretory pathway and is responsible for modifying proteins and lipids, as well as sorting newly synthesized molecules to their correct destination. As a consequence of these important roles, any changes in its proteome can negatively affect its function and in turn lead to disease.

Disruption of specific transport steps between the endoplasmic reticulum (ER), Golgi complex, endosomal-lysosomal system and the plasma membrane all can have dramatic consequences on the cell, and increasingly defects in the molecular machinery regulating membrane traffic are being linked to hereditary diseases.

Any changes to the proteome of the Golgi complex would affect its homeostasis and consequently the flux of proteins trafficking through it.

One possible consequence of mutations in Golgi complex proteins is that they cause gross changes in the morphology of the entire organelle and protein mislocalization, which together result in functional problems such as impairment of glycosylation.

Genetic studies of humans and mice continue to highlight the nonredundant mechanical role of components in complexes that anchor cells to extracellular matrices. At the same time, recent data provide exciting insights into, critical roles of transcription factors in regulating differentiation and function of matrix-producing cells.

The chemical stockroom also contains a solution labeled unknown. This solution contains a 0.10M solution of a "synthetic base".

arsen [322]

Answer:

AT indicates A and T bound together, AC indicates A and C bound together, etc.

Explanation:

In the '30s and '40s, biologists knew that the agent for heredity was in thread-like chromosomes, made of the molecule DNA. They also knew that DNA was made of four bases, (A)denine, (G)uanine, (C)ytosine, and (T)hymine. The race was on to be first to determine how they fit together, and how they carried hereditary information.

DNA

In 1953, James Watson and Francis Crick unraveled the mystery, by showing that DNA had the double-helix structure shown to the left. The information is stored as the sequence of bases: G, C, A, and T, on the strand of DNA running up one side of the double helix. On the opposing strand, the sequence is mirrored such that a C is paired with every G, and an A is paired with every T. This pairing is essential to the ability of DNA to replicate and to send its information out into the cell to direct protein synthesis.

You will be provided with stock solutions of all four bases. These are labeled dAMP for A, dCMP for C, dGMP for G, and dTMP for T to reflect the fact that these bases are only soluble as single bases in their d-MonoPhosphate form. Each of these solutions has a concentration of 0.10M. In the following, feel free to combine these solutions in any way you see fit. Note that the "Solution Info" window shows the concentrations of all chemical species in the currently-selected container. In this window, AT indicates A and T bound together, AC indicates A and C bound together, etc.
