  • how could a normal blood cell form intto a sickle cell intsantly???

  • Sickle cells have the normal concave disc shape under high-oxygen conditions; they only become their classic "C" shape when they are deoxygenated.

  • is there anyway i can get this video for a power point in science?

  • i hav it too.such horrible pain

  • i have sickle cell disease and this is an animation of a sickle cell crisis..these are very painful episodes of when ur blood cells turn into a sickle or the letter C shape and when blood clots this is what happens

  • and have many other issues in terms of transporting oxygen to required places around the body. the defective triplet code is a replacement of Glu for Val in the DNA protein code

  • ...however, if this reccessive allele is found in both parents of a person, they have a 1/4 chance of contracting the life threatening disease on sickle cell anaemia, which gives haemoglobin and therefore the red blood cell a rigid texture which results in stretching of numerous cells which a poor at transporting oxygen and cannot fit through tiny capillaries, sometimes causing unwanted clots. The effected person will then appear very pale,....

  • If you know about Sickle Cell Anemia, it is when the red blood cells are affected and change shape because it doesn't have the same type of hemoglobin as normal cells. So this animation is basically displaying how this transformation of cells occur. The sickle cells are not flexible and cannot move properly throughout the body which causes problems. Look up more on the disease if you want to learn about symptoms and how it affects people's lives.

  • ...due to, a genetic mutation which thrived due to natural selection in tropical regions where malaria rates are high, the haemaglobin defect gene prevented death to those who contracted the disease...

  • from what i can gather from this animation sickle cell is when the red blood cells get all disfigured....

  • this does not explain anything at all

  • this is cool and sick at tha same time.LOLL

  • @UrgedCRUSHER well it may look that way but its definitely no joke.sicklecell is so painful i shuld know cuz i got it.its somethin about it skipping generations in a person's family.extremely painful.weird thing iz i have it but i know maybe 10-15 facts about it.i never cared much to learn about it but its real serious.
