What is a characteristic of nucleic acids in which the sequence of bases on one strand is paired to the sequence of bases on the other?
Complementary base pairing is the characteristic of nucleic acids where adenine pairs with thymine (or uracil in RNA) and cytosine pairs with guanine. This pairing allows the two strands of DNA or RNA to form a stable double helix structure.
Why can you predict the base sequence of one stand in a molecule of DNA if you know the sequence of the other stand?
DNA is made up four nucleotide bases,a pentose sugar and a phosphate. The four nucleotides are adenine, guanine, cytosine and thymine. Due to the nature of these molecules they fall into two groups called purines ( adenine an guanine) and pyrimidines ( cytosine and thymine). The bases have complimentary base pairing causing the double helix shape of DNA. adenine always bonds with thymjine and guanine with cytosine. So you can predict what the base sequence of one strand the other strand will be the opposite base pairing, for example if you know that a strand is AGAACTG the complimentary strand is TCTTGAC.
What feature of a DNA molecule ensures accurate replication of the strands during each PCR cycle?
The complementary base pairing of nucleotides is what ensures accurate replication of the DNA molecule during each PCR cycle. This pairing dictates that adenine pairs with thymine and cytosine pairs with guanine, which allows for the faithful duplication of the original DNA sequence.
Why cant you predict the base sequence of one strand in a molecule of DNA if you know the sequence of the other 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.
What is the function of CCA sequence in t-RNA?
The CCA sequence at the 3' end of tRNA acts as the binding site for amino acids. This sequence is added post-transcriptionally by the enzyme tRNA nucleotidyl transferase and is essential for the accurate pairing of tRNA with its corresponding amino acid during protein synthesis.
What does the presence of the nucleotides adenine (A) and thymine (T) in a DNA sequence signify?
The presence of the nucleotides adenine (A) and thymine (T) in a DNA sequence signifies a complementary base pairing, where A always pairs with T.
What is a characteristic of nucleic acids in which the sequence of bases on one strand is paired to the sequence of bases on the other?
Complementary base pairing is the characteristic of nucleic acids where adenine pairs with thymine (or uracil in RNA) and cytosine pairs with guanine. This pairing allows the two strands of DNA or RNA to form a stable double helix structure.
What sequence of DNA bases bonds with the DNA base sequence atgt?
The complementary DNA base sequence that would bond with ATGT is TACA. In DNA, adenine pairs with thymine, and guanine pairs with cytosine. This follows the base pairing rules of DNA.

The code of DNA is specified in?
The code of DNA is specified in the sequence of nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up to form the double helix structure of DNA, with A pairing with T and C pairing with G. This sequence of bases contains the instructions for building and functioning of an organism.
Due to the strict pairing of nitrogen base pairs in DNA molecules the two strands are said to be what to each other?
Complementary. The base pairs in DNA always follow a specific pairing rule (A with T, and C with G), which means that the sequence of bases on one strand determines the sequence on the other, making them complementary.
If DNA has the sequence AAA then a segment of mRNA would be what?
If DNA has the sequence AAA, the corresponding mRNA segment would have the sequence UUU due to complementary base pairing during transcription. This mRNA sequence would then undergo translation in order to produce a protein based on the genetic information contained in the DNA.

What complementary strand to the DNA sequence TAGTCA is?
The DNA base pairing rules are A-T and C-G, so the complementary strand to TAGTCA is ATCAGT.
Difference between kozak sequence and Shine-Dalgarno sequence?
The Kozak sequence is a short sequence surrounding the start codon in eukaryotic mRNA that helps in the initiation of translation. The Shine-Dalgarno sequence is a purine-rich sequence in bacterial mRNA that helps in ribosome binding and initiation of translation by base pairing with the 16S rRNA in the small ribosomal subunit. Both sequences play crucial roles in initiating protein synthesis in their respective organisms.
What sequence in mRNA complements the sequence in the DNA template?
The sequence in mRNA is complementary to the DNA template, with thymine (T) in DNA being replaced by uracil (U) in mRNA. The complementary base pairing rules still apply: adenine (A) pairs with uracil (U), and guanine (G) pairs with cytosine (C).
