Today, we went in depth into DNA. We went through that DNA uses a code to form different types of proteins to make different tissues or organs. The DNA code is the same as words as both make use of letters and when one letter is changed, the whole meaning is different. But this DNA code has a special name called condons. Codons are instructions to make different types of proteins. Alot of codons add up to form DNA. Codons makes use of 4 different letters(A, T, C, G)and only has a combination of 3 letters. The letters A, T, C and G have a special name known as Nitrogenou Bases. A stands for adenine, T stands for thymine, C stands for cytosine and G stands for guanine. For example, a single strand DNA may be like:
TAG CCG CGT TAG ACG TGA
DNA comes in a pair but the other half is complimentary of the original one. So A will always go with T and G will always go with C. So the complimentary strand of the single strand DNA above is like that:
ATC GGC GCA ATC TGC ACT
The double stranded DNA will twist into something like a spiral staircase withn a hollow interior. This is called DNA double helix.
After going through the topic, we were tasked to make a DNA model using stickers and 2 wires. We were given a total of 20 stickers. And on 5 stickers per letter(A, T, C, G), we were required to write a letter on both ends of the sticker. Then we pasted the stickers on the wires following the rule: A goes with T and G goes with C. And this is how my DNA looks like.
