First Sequenced human chromosome

Do you know?

The first human chromosome to be sequenced is chromosome no 22.

The sequencing completed
in December 1999

The genetic code of it comprised of 33.5 million bases

About Chromosome 22

Chromosome 22 is the second smallest of the human autosomes. The short arm (22p) contains a series of tandem repeat structures including the array of genes that encode the structural RNAs of the ribosomes, and is highly similar to the short arms of chromosomes 13, 14, 15 and 21. The long arm (22q) is the portion of human chromosome 22 that contains the protein coding genes and this is the region that has now been sequenced. The completed sequence consisted of 12 contiguous segments covering 33.4 million bps separated by 11 gaps of known size. One of these gaps has subsequenctly been closed by the Oklahoma group. The sequence is estimated to cover 97% of 22q, and is complete to the limits of currently available reagents and methodologies. The largest contiguous contig is >23 million bps, and at that time, this was the largest piece of continuous sequence determined

The overview of fair democracy: https://iambrainstorming.wordpress.com/from-hypocrisy-to-democracy-this-way-delegated-proof-of-stake-2/   Evolutionary democracy using hierarchical specialization with adapted delegated proof of stake algorithm, where different specialized departments are in a symbiotic or mutually beneficial relationship.  The Tree of Democracy Each funnel is a department with its subdepartments A Department For example, the education department can have its sub-departments such as kid education, adult education, research, entrepreneurship. Each department consists of large outer representatives and a few inner representatives. These large outer representatives are the grand total of all its sub-department outer representatives and the few inner representatives are the grand totals of all its sub-department inner representatives. Inner representatives of center and state are policy approver,   and inner representatives of all the regions (center, state, ...

A new fair democracy inspired by Delegated Proof of Stake algorithm

Preprint link: https://osf.io/82mpk/ dem·oc·racy [democracy democracies] 1) fair and equal treatment of everyone in a country or organization, etc, and their right to take part in making decisions 2) a system of government in which all the people of a country can vote to elect their representatives Yes, most democratic countries fulfill the second definition of democracy, but none to the first definition. Abstract: Democracy is about fair and equal treatment of everyone in a country. But it becomes unrealistic to achieve when political parties have their conflict of interest , and leaders don't have the expertise to make evidence-based policies and neither have the skill and manpower for solving problems that surround our society and ecosystem. The new fair democracy provides an elegant way of governance that separates the representative responsibility according to their specialization and can grow into any complexity. The governance is divided into various departments, and each ...

Importance of educational videos and solving its limitation by teachers assistance

Many technologies have promised to revolutionize education, but so far none has. With that in mind, what could revolutionize education? Why educational videos don't work? 1) Procrastination : Educational videos give freedom of anytime learning, but this can lead to procrastination. According to Parkinson's Law: "Work expands to fill the time available for its completion". But in case of video lectures or MOOCs there is no limit of time, so usually, we procrastinate. Limiting time to complete the MOOCs is also a bad idea, as it takes away its advantage of any time and anywhere learning. 2) Lack of a social interaction : We share emotions, feelings, discuss with the teacher, friends that come to our mind just like a true social animal and classroom brings a social two-way interaction, but it doesn't happen in case of MOOCs. 3) Answerability : No one is there to keep you accountable for finishing the course, no outward push, everything lies with intrinsic motivation...
