Haemoglobin: a quaternary-structure protein found in red blood cells.


Sickle Cell Anaemia

Sickle cell anaemia is a genetic disease caused by a single base substitution mutation within the gene (Hb) that codes for the alpha-globin polypeptide in haemoglobin. Most humans have the normal allele HbA.

The mutation that occurs:
Within the haemoglobin gene, the base thymine (T) is replaced by the base adenine (A), causing the DNA triplet GAG to mutate to GTG
The mutated DNA codon GTG is transcribed into the mRNA codon GUG, instead of GAG.
During translation the amino acid valine (VAL) replaces the original amino acid glutamic acid (GLU); this occurs on the sixth position of the polypeptide.
The results in a new allele, HbS.

Consequences:
The protein haemoglobin S is produced instead of haemoglobin A; this causes a distortion in the shape of the red blood cells into sickle shapes.
Sickle-shaped red blood cells have a limited oxygen-carrying capacity and block the capillaries limiting the flow of normal red blood cells, causing people with sickle cell anaemia to suffer from acute pain, fatigue and anaemia.
There is a correlation between sickle cell anaemia and malaria. In areas with increased malaria cases, there is an increased frequency of sickle cell alleles.

About Sweesh Eggs

Sweesh eggs are covered in patches of downy fur. When Sweesh eggs were first discovered many SAR Center scientists theorized as to the purpose of the fur. It turned out that the fur patches serve no discernible function.

Even though Sweesh are a common sight in Ark's forests, finding a Sweesh egg can be quite difficult. This is due in part to their small size. In addition to this many Sweesh nests are made inside the tops of large trees. Making finding and reaching a nest a bit difficult.

About the Sweesh Creature

Sweesh are nocturnal animals that live their entire lives in the treetops, gliding from branch to branch in search of food. The only time you'll see a Sweesh on the ground is if it became injured and fell. Sweesh are very social creatures and will form social groups with up to a dozen adults. These groups work together to find food, keep watch for predators, and tend nests together. Due to these two behaviors it is highly recommended that any Ark citizen wishing to own a Sweesh should get at least three and build a series of specialized perches in their home to simulate a treetop environment.
