+**Which basic building blocks is the ribosome made of? / Vad är ribosomen huvudsakligen uppbyggd av?**
+
+**Answer**
+```spoiler-block
+
+It is made of rRNA and proteins. rRNA is in the center of both the large subunit and the small subunit. The proteins are more in the periphery.
+
+As described the ribosome has a large and a small subunit. In prokaryotes the small subunit is 30S and the large is 50S – they together form the 70S ribosome. In eukaryotes the ribosome is a bigger, the small subunit is 40S and the bigger is 60S – they form the 80S ribosome.
+
+The small subunits is where the t-RNA´s anticodon pairs with the codon on the RNA strand, in the large subunit the peptide-bond is formed.
