Commonly used tools for alignment (FASTA, BLAST, BLAT)

Alright, let's break it down!

  • FASTA: Imagine you have a big library filled with books, and you want to find one specific book among them. FASTA is like a super-fast librarian who helps you find similar sequences of genetic information (like DNA or protein sequences) in a huge database. It looks for patterns and similarities between your sequence and the sequences in the database.
  • BLAST (Basic Local Alignment Search Tool): BLAST is like a detective for genetic information. It searches through a database to find similar sequences to the one you provide. But it's not just looking for exact matches; it's smart enough to find similar sequences even if there are slight differences or mutations. It's widely used by scientists to compare DNA, RNA, or protein sequences and understand their functions and relationships.
  • BLAT (BLAST-Like Alignment Tool): BLAT is similar to BLAST but works even faster for certain types of searches. It's like a super-speedy investigator that quickly finds regions in a genome that match your query. It's often used when you have a large genome and need to find specific regions or genes quickly.

So, in simple terms, FASTA, BLAST, and BLAT are tools that help scientists search through vast amounts of genetic data to find similar sequences, helping them understand the genetic code better and unravel mysteries in biology.

Charter of Queen Elizabeth I & the East India Company

  Charter of Queen Elizabeth I & the East India Company   Background Francis Drake’s Voyage (1580) : First Englishman to sail around the world, inspiring exploration. Defeat of Spanish Armada (1588) : England’s naval victory boosted confidence to challenge Spain/Portugal in global trade. Portuguese & Dutch Profits : Europeans made huge money from Asian spices, textiles, and goods → England wanted a share! Formation of the East India Company 1599 : Group of English merchants ( Merchant Adventurers ) formed a company to trade in Asia. 31 December 1600 :  Queen Elizabeth I  granted them a  Royal Charter , giving: Exclusive Rights : Only this company could trade east of Africa (monopoly). Name : “Governor and Company of Merchants of London trading into the East Indies” (later called  East India Company ). 1609 : Monopoly extended  indefi...
