What is the unique sequence of DNA base pairs that can be used to identify a person at the molecular level?
The unique sequence of DNA base pairs that can be used to identify a person at the molecular level is called a DNA fingerprint.
What kind of molecular evidence supports evolution?
DNA and protein sequence similarities among different species provide strong molecular evidence for evolution. Mutations in DNA that accumulate over time can be used to construct phylogenetic trees, showing the relatedness between different species. Comparative genomics also reveals shared genetic elements and patterns of gene expression that support the concept of common ancestry.
What are ddNTPs used for in molecular biology research?
ddNTPs, or dideoxynucleotide triphosphates, are used in molecular biology research for DNA sequencing. They terminate DNA synthesis when incorporated into a growing DNA strand, allowing for the determination of the sequence of nucleotides in a DNA molecule.
What does molecular evidence mean?
Molecular evidence refers to biological data obtained at the molecular level, such as DNA sequences or protein structures. This kind of evidence is used in various scientific disciplines, including genetics, evolutionary biology, and biochemistry, to study relationships among organisms, genetic variation, and other molecular processes.
What is the molecular weight of a base pair and how does it impact the overall structure of DNA?
The molecular weight of a base pair in DNA is approximately 650 daltons. Base pairs are the building blocks of DNA, and their specific sequence determines the genetic information encoded in the DNA molecule. The molecular weight of base pairs impacts the overall structure of DNA by contributing to its stability and ability to store and transmit genetic information.

What is the scientific name for a palindrome?
In molecular biology, a palindromic sequence is a nucleic acid sequence on double-stranded DNA or RNA.
The genetic code of a DNA molecule is determined by a specific sequence of?
Molecular bases
What provide evidence of common ancestry amongisms?
Simularities in DNA sequence

What is the strong evidence of common ancestry between the organism that share them?
Simularities in DNA sequence
What sequence best represents the relationship between DNA and the traits of an organism?
DNA contains the instructions for building proteins, which determine an organism's traits. The sequence is: DNA → RNA → proteins → traits of an organism. This process is known as the central dogma of molecular biology.

What is the molecular sequence which is the blueprint for a protein?
The molecular sequence that serves as the blueprint for a protein is the sequence of nucleotides in a gene, encoded in DNA. This sequence is transcribed into messenger RNA (mRNA), which carries the genetic information from the nucleus to the ribosomes. There, the mRNA sequence is translated into a specific sequence of amino acids, forming a protein. The order of nucleotides ultimately determines the structure and function of the protein.

Why is it possible to use a DNA sequence to identify bacteria?
Each bacterial species has a unique DNA sequence that can be used as a molecular fingerprint for identification. By comparing the DNA sequence of an unknown bacterium to a database of known bacterial sequences, scientists can determine the identity of the bacterium. This method is highly specific and accurate in distinguishing different bacterial species.
