There are four nucleotide bases that pair up to form the "ladder rungs" that we see on a DNA molecule. These are adenine, thymine, guanine, and cytosine.
Adenine matches with thymine, and guanine matches with cytosine. The opposite of each case also occurs (thymine will bind to adenine, and cytosine to guanine).

What is adding base pairs to the strand?
Base pairing between the DNA template strand and the RNA nucleotides
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.
Why is one strand of the DNA molecule labeled Template DNA?
DNA acts as a template for two things: # DNA # mRNA transcripts This is possible because each nitrogenous base in one strand pairs only with one other base in the complementary strand as follows: Adenine (A) always pairs with Thymine (T) Guanine (G) always pairs with Cytosine (C) Note: in RNA, Uracil (U) takes the place of Thymine (T), but still always pairs with Adenine (A). So, if one looks at a single strand of DNA, one can reconstruct the sequence of the complementary strand from the original strand, because each base on one strand will pair with only one base on the other. Consider this single strand of DNA: DNA acts as a template because of one fact: each nitrogenous base in one strand pairs only with one other base in the complementary strand as follows: Adenine always pairs with Thymine (or Uracil in RNA) Guanine always pairs with Cytosine So, if one looks at a single strand of DNA, one can reconstruct the sequence of the complementary strand from the original strand, because each base on one strand will pair with only one base on the other. Consider this single strand of DNA: ATTGCAT Looking at the first base, we know that A always pairs with T, and that T always pairs with A for the second base, and so on. Therefore we can reconstruct the complementary strand is: TAACGTA The mRNA transcript would be: UAACGUA This fact is important in two ways. First, when a cell needs to replicate its DNA, it uses an enzyme, DNA Polymerase, to assemble complementary strands by adding nucleotides with the appropriate matching bases along the strand. The result is two identical, complete DNA molecules. Secondly, when the cell needs to build messenger RNA for protein synthesis, it uses an enzyme called RNA Polymerase to assemble the mRNA transcript by adding RNA nucleotides with the complementary matching bases from the DNA strand. The result is an mRNA transcript which will be translated into a protein whose amino acid sequence will reflect the codon sequence of the original DNA strand.
What nucleotide base in DNA is replaced by a base in RNA?
In DNA thymine is one of the nitrogen bases, but in RNA uracil replaces thymine still leaving four nitrogen bases
What strand of DNA would be produced from the template strand of DNA?
AAC CT would produce TTG GA The coding strand is the DNA strand that has the same base sequence as the RNA transcript. It contains codons, and the non-coding strand has anti-codons instead.
What is adding base pairs to the strand?
Base pairing between the DNA template strand and the RNA nucleotides
What RNA pairs with adenine?
The phosphate base that pairs with Adenine in RNA is Uracil. In a DNA strand Adenine would pair with Thymine.

Why is RNA needed to create proteins?
RNA is a single-stranded structure that is copied from an unzipped DNA strand identically, this is called transcription. The RNA strand contains the complementary base pairs for the DNA sequence. The DNA strand has sections that code for specific proteins, so when the RNA strand is created from the DNA, the RNA strand is then able to recreate the sequence that codes for the proteins. The RNA strand leaves the nucleus, via a nuclear pore, and enters the cytoplasm. In the cytoplasm the RNA strand binds to two Ribosomal subunits, and translation is carried out, producing proteins.

If the nucleotide or base sequence of the DNA strand used as a template for messanger RNA synthsis is ACGTT then the sequence of bases in the correspnding mRNA would be?
For a DNA strand having the code, "aac tae ggt" the corresponding rna strand would be: "UUG AU? CCA". There is no "e" pyridine, so I do not know what would pair with "e." In DNA, the purines are Adenine and Guanine, and the pairing pyrimidines are Cytosine and Thymine, respectively. Thus, in DNA, A pairs with T and G pairs with C. In rna, the pyrimidines are again Adenine and Guanine, but the pairing pyrimidines are Uracil and Cytosine respectively. In rna, A pairs with U and G pairs with C
Is transcription the manufacture of a strand of RNA complementary to a strand of DNA?
Yes. The strand of RNA is messenger RNA, mRNA.
Adenine complements with what in DNA RNA?
In DNA: Adenine base pairs with Thyamine A=T In RNA: Adenine base pairs with Uracil A=U
What is is called when RNA copies to DNA?
When RNA's base sequence is used to determine the base sequence of a new strand of DNA, that is called reverse transcription.This is because the process is the reverse of transcription, which involves copying the base sequence of DNA to form RNA, including messenger RNA (mRNA).
What base pairs with thymine in DNA and with uracil in RNA?
Arginine
