If you consider the haploid human genome occupies a total of just over 3 billion DNA base pairs, and the genome is stored on 23 chromosome pairs.3,000,000,000 / 23 = 130,000,000 (rounded to nearest hundred thousand).So one gene is roughly one-hundred-million base pairs.
A stands for adenine, one of the four nitrogen-containing bases in DNA. By the rules of complementary base pairing, A always pairs with T (thymine). Adenine is a purine (a base with a double ring structure). T is a pyrimidine (a base with a single ring structure). Each pair of bases always consists of a purine and a pyrimidine. A and T form two hydrogen bonds between them; G and C form three.

There are 7 base SI units and all other are defined using these 7 base units. See the related question below:[http://wiki.answers.com/Q/What_are_all_the_SI_unitsWhat are all SI units?]
The process is to first get the microscope to work after you do that you have to adjust it to see what you are trying to look at. Or A method and calibration standard for fabricating on a single substrate a series of crystalline pairs such that the d-spacing difference between the pairs will generate Moire fringes of the correct spacings to optimally calibrate the magnification settings of an electron microscope over a variety of magnification settings in the range of 5000× to 200,000×.

Minimal pairs are pairs of words that except for one phenomic difference sound alike. The one phenome difference can make a significant difference in meaning between the two words. e.g. beat-bear, wet-wit, ten-teen etc. For further examples of minimal pairs, please see related links below.
This question requires a strand of mRNA to be given so you can copy the codons and then find the anticodons which will give you the amino acids. Your question is identical to mine from a work booklet pg 68#6 just flip back to page 67 and you'll see a 14 codon mRNA strand!
The graduates walked in pairs down the aisle. The pairs of shoes were lined up neatly outside the dojo.
The four bases of RNA are adenine guanine cytosine and uracil. (Uracil is only found in RNA) The four bases of DNA are adenine, guanine, cytosine and thyamine (thyamine replaces uracil in DNA). The bases in uracil are denoted A, G, C and U. When RNA pairs with DNA, A of the DNA always pairs with U of the RNA, T of the DNA always pairs with A of the RNA, and C and G always pair with each other. If you look at a drawing of each molecule, it is easy to see that each pair of complementary bases are perfectly matched for each other. The bases pair with each other through hydrogen bonding. This is a very strong type of bond that occurs between a hydrogen and an electronegative atom (such as F, O or N). The bases are cyclic structures of carbons and hydrogens, and they have some N-H groups and carboxylic groups. So the bases of RNA pair with their complementary bases in DNA by hydrogen bonding between the N-H groups on one base with the oxygen of the carboxylic group on the complementary base.

Only one mRNA codon codes for Methionine - AUG.

The transcription of mRNA begins in the nucleus. The DNA is uncoiled and the nucleic acids with nitrogen bases adenine, thymine, guanine, and cytosine combine to form an incomplete mRNA. The current RNA contains exons (the coding region) and introns (non-informational regions). The introns are cut out and remaining exons are spliced together. Now the mRNA goes through polyadenylation. This is the process where the 3' end of the mRNA is attached with multiple adenine nucleotides. On the 5' end of the mRNA, a 5' cap is attached. This is the complete and functional mRNA. At this point, the mRNA exits the nucleus to join with the ribosome, ending the transcription and starting the process of translation.

The two strands in a DNA molecule (the polynucleotides) are complementary to each other. This means that the base sequence in one strand determines the base sequence in the other strand. This happens because of specific base pairing. An adenine in one strand always pairs with a thymine in the other strand, and a cytosine in one strand always pairs with a guanine in the other strand. So if you know the base sequence in one strand of the DNA yoiu can work out the sequence in the complementary strand. See: http://www.phschool.com/science/biology_place/biocoach/dnarep/basepair.htmlDNA strands run anti-parallel from one another, and have a double helix structure. The strands are held together by hydrogen bonds between base pairs that are weak individually, but collectively strong.
You can graph the values and see if the points fall on a straight line. You can also calculate delta-y / delta-x (i.e., difference between y values / difference in x values) for pairs of adjacent points, and see whether this value is the same in all cases. Or at least similar - you may want to allow for errors in measurement, or rounding errors.
