Document Summary
**announcement from prof: mistake in the following slide. When it gets synthesised, it becomes a penta-peptide. Hence, the addition of another d-alanine (seen in red) (gram -ve on top and gram +ve on the bottom) Rna is usually ss and read 5" 3". Rna can coil back on itself and make complementary base pairing which is why we never really see it in single strand form. The sugars contain an oh group at the 2" position. The nitrogenous bases are agcu instead of acgt: au and gc bping. Associated with small basic proteins called histones this aids with compaction. No nucleus, the dna is free-floating in the cytoplasm but is anchored to the cell membrane. It must be anchored to the cell membrane in order for division to occur successfully. It is compacted but not nearly as compacted as the dna in eukaryotic cells.
