Which of the following is true regarding complementary base pairing in DNA and RNA molecules?
Although the base pairing between two strands of DNA in a DNA molecule can be thousands to millions of base pairs long, base pairing in an RNA molecule is limited to short stretches of nucleotides in the same molecule or between two RNA molecules.
If one strand of a DNA molecule has the sequence of bases 5'attgca3' the other complementary?

In DNA complementary base pairing occurs between what?
Adenine pairs with Thymine ( A-T) Guanine pairs with cytosine ( G-C)
Due to the strict pairing of nitrogen base pairs in DNA molecules the two strands are said to be what to each other?
complmentary
Base pair in RNA?
RNA has four different base pairs. Adenine, cytosine, uracil, and guanine are the base pairs. These base pairs are made when a transcription initiation complex moves along DNA, unzips it, and creates RNA. Unlike DNA, RNA is one stranded and the base pair thymine is not present. Instead, uracil bonds with adenine.
What is specific base pairing?
a pair of nitrogenous bases,consisting of a purine linked by hydrozen bonds to a pyrimidine that connects the complementary strands . the base pair are adenine,thymine,cytosine & guanine in DNA & uracil in place of thymine in RNA.
Where do hyrdrogen bonds form in the DNA molecule?
across the nitrogenous bases, they form between the complementary base pairs Thymine and Adenine and also cytosine and guanine
What are complementary base-pairs?
Adrenine (A) pairs with Thymine (T) Cytosine (C) pairs with Guanine (G)

As a DNA molecule splits what is added to the exposed base on the original molecule?
Complementary nucleotides
What base always base pairs with guanine?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
How are base pairing rules and complementary base pairs related?
Base pairing rules and complementary base rules are related because of DNA. If one can find the base pairing on a strand of DNA, usually the complementary base is easily found.
If one strand of a DNA molecule has the sequence of bases 5'attgca3' the other complementary?

Explain the components of DNA and explain its functional relationship to RNA and protein?
DNA or Deoxyhydro-Neucleic Acid is composed of base pairs, nitrogen and phosphates. The nitrogen and phosphates form the backbone of the DNA structure and take the shape of a double helix with the base pairs on the inside and the backbone on the outside. Thus, a molecule of DNA is actually two separate chains interwoven. The base pairs contain the information and most of the time are protected on the inside of the helix. There are four base pairs, adenine, guanine, cytosine, and thymine (represented by the letters A, T, C, and G) A bonds with T, C bonds with G via hydrogen bonding. A cannot bond to either C or G. This is a major function of the structure of DNA in protecting the information it contains. Should a base pair be incorrectly placed, the molecule will not fold up correctly, and an enzyme will likely find the problem and insert the correct base pair. This base pair bonding makes duplicating the molecule quite easy. The DNA helix unwinds, leaving two separate strands. The base pair sequences on these two strands are complementary to each other. Where there is a C on the first chain, there will be a G on the other. So to copy the molecule, complementary base pairs can be inserted onto the open chain and a back bone bonded to the new base pairs and the resultant will be two identical helices of DNA. A similar mechanism is employed in DNAs transcription To RNA. To be read, the DNA molecule unwinds, leaving two complementary chains. The chain that contains the information starts with a certain sequence which labels it as the one containing useful information. RNA base pairs are inserted onto the DNA chain in the same manner as DNA base pairs would be to copy the molecule with a few exceptions. There is no RNA base pair for thymine, instead the base pair Uracil is used. Uracil is complementary to Adenine. The backbone is also subtly different, though its immaterial to the transcription process. Once completed, this molecule of messenger RNA is complementary to the molecule of DNA, whose information it now encodes. The messenger RNA is what the protein is constructed off of. Transcription enzymes are used for such purpose and have a triplet of base pairs on one end and a amino acid on the other. The triplet of base pairs lines up with a triplet on the messenger RNA and one by one a chain of amino acids is put together. once the transcription enzymes get to the end of the messenger RNA molecule, the protein folds up.
What factor maintains the same distance strands in a DNa molecule?
Depending on what "Strands" are it could be either Hydrogen bonding between complementary base pairs or Phosphate bonds between interlinking deoxyribose sugars
