![]() ![]() This kind of content review for the MCAT is not necessary. You are basically re-learning the stuff you should have learned during your pre-med prerequisites. Either with a tutor, class, or self-paced MCAT course, you will systematically review every topic in a condensed format. Your traditional MCAT course will have a curriculum that essentially covers every subject that could be tested on the MCAT with practice questions to reinforce the learning of those topics. Is Content Review Necessary For The MCAT? This is valuable because the psych/soc section ( being the newest section on the MCAT) is still lacking in options for quality review material. Lots of students agree that Khan Academies’ strongest subject is the psychology/sociology section. This not only saved me time but also helped me develop a deeper understanding of the subject matter. What a video could teach me in 15 minutes could take up to an hour of reading for me. This is really helpful for people like me who are visual learners. Khan Academy is known for its very thorough teaching videos. They were so good at covering everything on the MCAT that I could have gotten away with not purchasing an MCAT review book. While reviewing my practice tests, I would frequently go back to Khan Academy to watch videos on subjects that I struggled with. When I was studying for the MCAT, I found Khan Academy to be very useful. You will need to invest in practice problems books and full-length practice exams. You could get by without purchasing a content review book like Kaplan or The Princeton Review but there are just not enough good quality practice problems. Therefore, yes, Khan Academy is good enough for MCAT content review.īut that is considering only content review, not practice problems. They have a huge database of videos that exhaustively cover every topic on the MCAT. ![]() Khan academy’s content was created in partnership with the AAMC so you are getting material that is influenced by people who create the MCAT tests. Is Khan Academy Good Enough For MCAT Content Review? Let’s dive a little deeper into this topic in order to see how useful Khan Academy is when studying for the MCAT. Khan Academy content review for the MCAT pretty much covers everything you need to know but it does not provide you with enough practice problems to study properly for the MCAT. Note having palindromic sequences along short the short stretches over which restriction enzymes function is not common.Khan Academy has been a popular choice for premed students studying for the MCAT primarily for 2 reasons: It’s free and it was created in partnership with the AAMC which happens to be the creators of the MCAT.Įven though Khan Academy is a very comprehensive resource, alone it is not enough for your MCAT preparation. Having short stretches of DNA that read the same on both strands of double-stranded DNA allow restriction enzymes to cut both strands in the same place. ![]() Calculate the reverse complement of the whole forward strand to finish the reverse strand: ATCGAT.Reverse the order of the reverse complement ( CTA) and add it to the end of the forward strand - TAGCTA.Calculate the reverse complement of the sequence - ATC.Starting with the original sequence - TAG.TAGCTA) can be reconstructed from just knowing the first three bases on one strand: For example, a six-base recognition sequence (e.g. This pattern makes it possible to reconstruct a palindromic sequence from one-half of one strand. The complement to the whole six base strand is CCTAGG, read backwards (as it would be when reading from 5’ to 3’ on the complementary strand) is GGATCC, an exact match for the original strand. Note the first three bases GGA are followed by the complement of those three bases in reverse order: TCC. For example the recognition sequence for BamHI is GGATCC. Palindromic sequences are a short run of bases (typically 3 to 5 in length), follow by their complementary bases in reverse order. They are probably more properly referred to as palindromic sequences to distinguish them from language palindromes. In English, the term palindrome refers to a string of letters that have the same meaning written in both directions some classic English palindrome are kayak, civic, noon, and racecar.Īs a set of paired sequences (one on each of the strands of a double strand of DNA), the palindromes recognized by restriction enzymes follow a slightly different set of rules. ![]()
