In DNA A pairs with?
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.

What the difference between SI base unit and SI derived unit?
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?]
What amino acid would be made form the mRNA code for a a a?
AGT codes for the amino acid serine and CTT codes for the amino acid leucine.
Which is the largest chromosome?
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.
Which bases pair with each other in the DNA double helix?
In DNA, the four Nitrogenous bases are A= Adenine, T= Thymine, C= Cytosine, and G= Guanine. A pairs with T and G pairs with C through strong bonds called "Hydrogen Bond." A-T base-pairs are held together by 2 Hydrogen bonds, whereas, G-T base-pairs are held together by 3 Hydrogen bonds. If you are familiar with their structures, you can easily see where the "active" part of the molecules are located, aka where the Hydrogen bonds are formed.WARNING: As these particular bonds are the most desirable and MOST COMMON, it is POSSIBLE for a scenario to occur, where for example, an A (Adenine) binds to G (Guanine) base. Such a case, would therefore lead to what is known as a "mutation," during the Replication Process of DNA. There are numerous types of causes (i.e., natural vs. "unnatural"), types (i.e., deletion, insertion, etc), and results (i.e., gene expression) of mutations.
What are minimal pairs?
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.
Number the mRNA codons in the transparency from left to right Write down the anticodon each codon pairs with Then translate each codon into the amino acid it codes for Use the chart in your text to?
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!
How can you see the word pairs in a sentence?

What are the four nitrogen bases of DNA and how do they pair?
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.

How many different mRNA correspond to arginine?
These will be the codes for arginine: CGU, CGC, CGA, and CGG. See the chart at the link below:
How do you know if a table of value is linear?
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.
What is the relationship of the two DNA strands to each other?
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.
A double-stranded DNA molecule contains a total of 120 purines and 120 pyrimidines This DNA molecule could be composed of?
I don't really understand the point of the question but let's see what we can do. Purines are Adenine and Guanine Pyrimidines are Tyimine and Cytosine Since A pairs with T and G pairs with C, the molecule can be composed of any number of ACTG where A+G=C+T=120 and A=T and G=C Hope that helps.

AGT codes for the amino acid serine and CTT codes for the amino acid leucine.
