in DNA, each base pairs up with only one other base
You can predict the base sequence of one strand of DNA if you know the sequence of the other strand because DNA strands are complementary. Adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This complementary base pairing allows the sequence of one strand to dictate the sequence of the other, enabling accurate predictions of the base sequence.
In DNA, the other strand of the helix would have complementary base pairs to the original strand. Adenine pairs with thymine, and cytosine pairs with guanine. So, if one strand has the sequence ATTGC, the complementary strand would be TAACG.
To determine the base sequence on the complementary DNA strand, you need to know the base sequence of one strand. DNA is composed of four bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The complementary base pairing rules state that A pairs with T and C pairs with G. For example, if the given strand is 5'-ATCG-3', the complementary strand would be 3'-TAGC-5'.
They would be described as being complementary - as in complementary base pairing.

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.
In DNA, the other strand of the helix would have complementary base pairs to the original strand. Adenine pairs with thymine, and cytosine pairs with guanine. So, if one strand has the sequence ATTGC, the complementary strand would be TAACG.
They would be described as being complementary - as in complementary base pairing.
You can predict the base seqences of a DNA molecule if you know what one strand is, because of double Stranded DNA. Each strand matches up with a letter and repeats a pattern throught the entire DNA strand.
Each strand in the double helix is complementary rather than identical to the opposite strand. The bases in one strand pair up with specific bases in the opposite strand according to the base pairing rule (A with T and C with G). This complementary base pairing allows each strand to serve as a template for the synthesis of a new strand during DNA replication.

in DNA, each base pairs up with only one other base
The base sequence CAGACT corresponds to the DNA strand, and it would be complementary to the RNA strand with the sequence GUCUGA. Therefore, the original strand is the DNA strand.
You can predict the base sequence of one strand of DNA if you know the sequence of the complementary strand because DNA strands are complementary and follow base-pairing rules (adenine pairs with thymine, and cytosine pairs with guanine). However, if the question implies difficulty in prediction, it may relate to factors such as DNA mutations, structural variations, or the presence of non-canonical base pairing that could complicate straightforward predictions. In typical scenarios, though, knowing one strand allows for the accurate determination of the other.
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.
