Explain How Cells Have Same Dna but Different Functions

Cells can perform different functions even if they have the exact same DNA by only using the instructions that are needed depending on their function. Now scientists are learning there is more to the story.

Seer Training Cell Function

The set of genes we have has the instructions for everything about us.

. Same- genetic material DNA 2. That is how cell types can be so different even though they have the same set of genes. DNA is packaged in a chromosome.

Somatic cells undergo mitosis and germ cells undergo meiosis. 9 How is it that different cells can respond in different ways to exactly the same signaling molecule even when they have identical receptors. Higher cells incorporate an ancient chromosome.

How can your muscle cells have the same exact DNA sequences as your nerve cells even though they look very different and perform very different functions. In one study they plucked neurons from. Neurons- send and receive signals.

While all cells have the same genes cells turn on different genes at different times in order to become specialized to their functions. The way in which the nucleotide subunits are lined together gives a DNA strand a chemical polarity. Genes can be turned on and off.

Each cell is living in its own environment and getting different signals that they act on. Some DNA does not encode protein. Muscle cell- contraction which helps in locomotion.

However they look and perform differently because some of the genes are turned on while the others are turned off via the process of GENE EXPRESSION. Like other prokaryotic cells this bacterial cell lacks a nucleus but has other cell parts including a plasma membrane cytoplasm ribosomes and DNA. Master genes control basic body plans.

This is because all cells in the body have the same genome but do not have the same epi-genome which controls gene expression. They provide structure to the body and convert the nutrients taken from the food into energy. Whether a heart cell skin cell or muscle cellthey all read from the same genetic blueprint.

Carrying oxygen and carbon dioxide in red blood cells transmittingreceiving electrical messages. Genes can be moved between species. DNA responds to signals from outside the cell.

If you think of DNA like the directions for making proteins you can see that even though every cell generally has the same directions if cells use different parts of the directions they will end up being different. Environmental cue -- Cell signal -- Cell turns on or off different genes based on these signals Recognizing that all cells have the same DNA is a good place to start. Cells are the building blocks of all living beings.

Each cell type just picks and chooses the recipes it wants to use. 10 How can most cells have the same genetic content and yet have different functions in the body. If we think of each sugar as a block with a protruding knob the 5 phosphate on one side and a hole the 3 hydroxyl on the other see Figure 4-3 each completed chain formed by interlocking knobs with holes will have all of its subunits lined up in the same orientation.

Also all cells of the body have the same DNA but different functions. This will make cells to have. This is because all of the cells in our bodies are formed from a single fertilized egg that forms the diploid zygote 2n after the fusion of one haploid sperm cell n with one haploid egg cell n.

We learned in biology class that every cell in the body has the same DNA. Different genes are active in different kinds of cells. Cells can perform different functions even if they have the exact same DNA by only using the instructions that are needed depending on their function.

Gametes sperm and egg cells have only half of the amount of DNA. They are of different shapes and sizes pretty much like bricks of the buildings. The cell division produces cells with the same genetic material which differentiates to form different types of cells and attain different functions on the type of genes activated as well location of the cells.

2marks Viruses are not considered to be living organisms because they lack metabolic machinery and cannot reproduce without a host cell. University of Southern California. New research into brain cells is revealing that their DNA blueprint is radically different than expected.

Symmetry breaking by environmental cues during embryogenesis is what causes cells that carry the same DNA to become different from one another and most species break that symmetry at fertilization or even earlier. This starts a cascade of compartmentalized gene expression that eventually gives rise to a functioning multicellular organism. Cells are complex and their components perform various functions in an organism.

The easy answer is. Walsh and his colleagues have discovered intricate mosaics in the brains of healthy people. To perform these functions they need different shapes.

Therefore a blood cell and skin cell possess exactly the same DNA sequence. Some exceptions to the rule are. This diagram shows the structure of a typical prokaryotic cell a bacterium.

B cells in our immune system have. Some DNA can jump. How can cells perform different functions when they all have the exact same dna Differentiation is the process by which basic cells become more specialized to perform a specific function.

Differentiation is the process by which basic cells become more specialized to perform a specific function. They all have the same DNA but different blueprints are activated depending on where they are in the body. At the molecular level these different types of cells contain the same DNA sequence as rightly stated in the question.

The DNA in cells creates proteins that are used for different purposes within different cells ex.
