have few amino acid sequence differences.
DNA and RNA (m and t) are made of nucleotides. Proteins like hemoglobin are composed of amino acids. The mRNA specifies the sequence information needed for making the hemoglobin protein. This information is a direct and temporary copy of information contained on a gene on DNA. The tRNA is a separate molecule the carries an amino acid on it. It is like a mediator. It has sequence that matches to a small part of the sequence being specified by the mRNA. When the tRNA moves into the right position on the mRNA, the amino acid detaches from the tRNA and is added to the growing protein or polypeptide chain.
They are two different proteins, like the difference between a train and a robot. The difference between one protein and the other is the amino acid sequence that comprises that protein and the molecular bonding that determines its shape. Shape determines function in a protein. If it loses its shape it can't do its job. The shape of insulin and hemoglobin is different so insulin binds with glucose and hemoglobin binds with oxygen.
Sickle cell disease is a group of disorders that affects molecule in red blood cells (hemoglobin) that delivers oxygen to cells throughout the body. Person with this disorder have typical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.

These are called the second differences. If they are all the same (non-zero) then the original sequence is a quadratic.

1123 is not a number included in the Fibonacci Sequence.
It is the sequence of first differences. If these are all the same (but not 0), then the original sequence is a linear arithmetic sequence. That is, a sequence whose nth term is of the form t(n) = an + b

* A cubic sequence is a sequence in which the third level of differences (D3) is constant. * It is represented by the function tn=an3+bn2+cn+d, where D3=6a, and a does not equal zero.
have few amino acid sequence differences.
The first thing to do when tackling a sequence is note the differences between the values. In this case they are 2, 3, 4 As they are not equal, we look at the differences of the differences: 1, 1 These are equal, so the equation for the sequence begins x2/2 The sequence minus x2/2 is 6.5, 7, 7.5, 8 The differences in this new sequence are 0.5, 0.5, 0.5 Thus the equation continues x2/2 + x/2 The sequence minus x2/2 + x/2 is 6, 6, 6, 6 Thus the entire equation is x2/2 + x/2 + 6, or more simply (x2+x+12)/2 Using this equation you can find the next few numbers of the sequence: 21, 27, 34, 42, 51...
To find the equation of a sequence, you first have to look at the differences between the numbers. In this case the differences are 4, and 4. Thus the equation begins 4n. The sequence minus 4n is: 3, 3, 3 Thus the equation in its entirety is that the value of the term in position n is 4n+3
