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 else can I help you with?
A DNA strand with the base sequence tgacgca codes for a strand of mrna the mrna will have what base sequence?
The mRNA sequence generated from the DNA strand tgacgca would be acugcgu. This is because mRNA is complementary to the DNA template strand, so DNA base T pairs with mRNA base A, DNA base G pairs with mRNA base C, DNA base A pairs with mRNA base U, and DNA base C pairs with mRNA base G.
What strand mrna would be produced from the strand of DNA gca tta?
UGA CUG
What is adding base pairs to the strand?
Adding base pairs to a strand refers to the process of DNA replication, where new nucleotides are paired with existing ones to create a complementary strand. This process is essential for cell division and genetic inheritance.
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 RNA pairs with adenine?
The phosphate base that pairs with Adenine in RNA is Uracil. In a DNA strand Adenine would pair with Thymine.
A DNA strand with the base sequence tgacgca codes for a strand of mrna the mrna will have what base sequence?
The mRNA sequence generated from the DNA strand tgacgca would be acugcgu. This is because mRNA is complementary to the DNA template strand, so DNA base T pairs with mRNA base A, DNA base G pairs with mRNA base C, DNA base A pairs with mRNA base U, and DNA base C pairs with mRNA base G.

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.
Figure 8.2 shows a single strand of DNA. choose the first three nucleotides of the complementary rna strand.?
To determine the first three nucleotides of the complementary RNA strand, you need to match the DNA bases with their RNA counterparts. In DNA, adenine (A) pairs with uracil (U) in RNA, thymine (T) pairs with adenine (A), cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C). If the first three nucleotides of the DNA strand are, for example, A, T, and C, the complementary RNA strand would have U, A, and G as its first three 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.
Which nitrogenous base pairs with cytosine in DNA and RNA?
In both DNA and RNA, cytosine pairs with guanine.

What nitrogenous base does adenine pair with in an RNA strand?
In an RNA strand, adenine (A) pairs with uracil (U).
What nitrogen base is found in RNA that pairs with adenine in DNA?
Uracil is the nitrogen base found in RNA that pairs with adenine in DNA.
CGT base triplet on DNA is copied into mRNA as?
CGT base triplet on DNA is copied into mRNA as GCA. This is because DNA and RNA follow complementary base pairing rules, where C in DNA pairs with G in RNA, G in DNA pairs with C in RNA, and T in DNA pairs with A in RNA.
