In the case of sickle cell anemia, what happens to the gene? To the protein?

Answer:

When a person has sickle cell anemia, the hemoglobin protein forms long chains that change the shape of the red blood cell. So, instead of a disc shaped structure that moves easily through blood vessels, sickled blood cells are shaped like bananas. The reason they have a sickled shape is because the underlying gene has the wrong instructions.

Explanation:

Recall that DNA contains four bases: Adenine, Guanine, Cytosine, and Thymine. The sequence of A's, T's, G's, and C's are what determines the protein that is built. Each set of three bases will code for a single amino acid. Proteins are simply chains of amino acids. To make proteins, DNA must send its code sequence to the ribosomes in the cell, but it needs a messenger to do that. Transcription is the process where DNA is converted to a molecule of messenger RNA (mRNA). The mRNA is then used to build a protein like hemoglobin. To determine the amino acid sequence of the gene, you must transcribe the DNA to RNA. The base pair rule is used to create RNA, but RNA does not contain thymine, it contains URACIL instead. This is why codon charts have U's in them and no T's.

A codon chart tells you what bases in RNA code for what amino acids. The ribosome combines all the amino acids to create a single protein, like hemoglobin. It takes three bases to determine one amino acid. Amino acids are usually abbreviated. GUC makes the amino acid valine, abbreviated as "Val". Sometimes, one of the letters in DNA gets switched with another letter, causing a mutation in the DNA. Many mutations don't have any effects, but some will change the amino acid made by the ribosomes. In the case of sickle cell anemia, just a single letter change alters the shape of the hemoglobin protein

Basically, the gene gets the wrong instructions, and ends up forming a sickle shaped blood cell.

From what i know, in sickle cell anemia the blood is lack of oxygen.

The haemoglobin run from the blood cell because reacted with nitric oxide, and so thats why the shape of the blood change into sickle-shaped like.

"Bottom-up" (or "data-driven") mechanisms are Group of answer choices
lukranit [14]

Answer: A. mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information.

Explanation:

Bottom-up mechanism is a process in which a body perceives an incoming stimulus and certain physiological changes occurs in the body working in the direction of upwards that is the signals are transferred to the brain so that the brain could interpret the stimulus. This mechanism suggests the fact that our perceptual experience is based upon the sensory stimuli.
