This one of my ever lasting questions. May be I asked the same to many.. Or I may hear the answer several time. But still now I am not able to get a clarity on it. The question remains the same.. Why there is a complementary strand? Yes of cause I am talking about the DNA.
We are all having double stranded DNA compliment to each other.
Is it really true that only one strand of these DNA get expressed?
Of only. One strand why there is two? OK it is true that it can increase stability. Ya well ,it act as a proof reader to eliminate mismatches during replication. The stability of the structure and function. I really wonder is that the only function of the complimentary strand. What it actually complimenting.
Nearly 70 to 80% genome of guinea pig and human are. Same. Ho! then the so called 30% is responsible for the variation. Is that really means the 70% is some level of basic genetic constitution of all livings. Not may be but its really confusing... More than 30% really.
I need to learn a lot basics.

Electronic Skin: Store ,send and receive data

Develop an artificial skin is one of the major challenge. And we are almost achieved the goal by nanotechnology. A wearable synthetic skin that can sense touch , temperature , movement and can response to it. Now we moved little bit ahead with a wearable skin which can store, send and receive data, Nature published the success in their latest edition .

The application of this technology is very vast. The initial target is to use this synthetic skin with data to aid patients with movement disabilities. The new improved version of skin can store data, drug, it can receive diagnostic information and can release drug, monitor movement, temperature and send data. The so called 'electronic skin' is a 0.3 mm thick 4 cm long and 2 cm wide stretchable nanomaterial.

The trade-off for that memory milestone is that the device works only if it is connected to a power supply and data transmitter, both of which need to be made similarly compact and flexible before the prototype can be used routinely in patients. Although some commercially available components, such as lithium batteries and radio-frequency identification tags, can do this work, they are too rigid for the soft-as-skin brand of electronic device. Even though the data is transmitted wirelessly, there should be a device that can read the data. The thought of using human body temperature or electric charge is also a thinkable approach to solve the energy requirement.

The electronic skin can also do things that conventional medical sensors cannot. When placed on the throat, for example, it senses spoken words well enough to control a simple computer game. The device might be used to help people with laryngeal diseases communicate, to monitor premature babies, or to enhance the control of prosthetics. Use the skin to induce muscle contractions in regions of the body that have degenerated.

Students Build the First Eukaryotic Chromosome from Scratch

The feat is a landmark achievement in synthetic biology

Credit: Science Source

In March undergraduate students in Johns Hopkins University's Build a Genome course announced they had made a yeast chromosome from scratch—and history, too. It is the first time anyone has synthesized the chromosome of a complex organism, a landmark achievement in the field of synthetic biology. It is also a triumph for the movement known as DIY biology.

The target was chromosome 3, which controls the yeast's sexual reproduction and has 316,617 base pairs of the DNA alphabet—A for adenine, G for guanine, C for cytosine and T for thymine. To synthesize it, the students took a shortcut: they built only the sections considered essential or nonrepetitive. The resulting chromosome had a more manageable 272,871 base pairs. And as reported in Science, the yeast with the new genes thrived just as well as regular yeast did in terms of size and growth.

“They are going strong,” says biologist Jef Boeke of New York University, who helped lead the research as part of the Synthetic Yeast 2.0 project—an effort to build a synthetic genome for yeast that would give scientists nearly complete control of it. Boeke and others plan to grow this batch for thousands of generations over the next several years to see how they evolve over time, which will give scientists a better understanding of fundamental biology, from the role of “junk DNA” to the absolute minimum of genetic code necessary for survival. “The questions are endless,” Boeke says.

The current work is just 3 percent of the way toward creating an entirely synthetic yeast genome (there are 16 chromosomes in total) and will take many more years to finish. If finished, synthetic yeast could be second on the list of organisms with genomes built from scratch—the J. Craig Venter Institute built a bacterium's genome in 2010.

It could also be a breakthrough in humanity's millennia-long cohabitation with Saccharomyces cerevisiae, which is responsible for bread and wine. Yeasts today churn out human proteins for medicines, biofuels and other specialty products. Being able to fine-tune the microscopic fungus's genetics could lead to better beer or sustainable chemicals, according to Boeke. And after yeast? “The fruit fly? The worm? We're not sure what is next.”
