What else can I help you with?
What refers to identifying an individual on the basis of repetitive nucleotide sequences in his or her DNA?
DNA fingerprinting
Is gcccaaag a molecule of dna?
No, "gcccaaag" is not a molecule of DNA. It is a string of nucleotide bases that could be part of a DNA sequence. DNA molecules are made up of sequences of nucleotide bases like adenine, cytosine, guanine, and thymine.
Are no two nucleotide sequences in DNA molecules ever the same?
Yes. This can happen via a gene duplication in a single organism or by shear coincidence (though its increasingly unlikely the biggest the sequence in question). Identical sequences can happen across species due to heredity from a common ancestor of a common gene or genetic marker, such as we see in ERVs and analysis from computational genomics.
True or false After replication the nucleotide sequences in both DNA molecules are identical to each other and to the original DNA molecule?
True. After replication, the nucleotide sequences in both DNA molecules are indeed identical to each other and to the original DNA molecule. This ensures that genetic information is accurately duplicated during cell division.
What types of DNA do scientists use to determine individual identities of organisms within the same species?
Scientists use genetic markers such as microsatellites or single nucleotide polymorphisms (SNPs) in DNA to determine individual identities of organisms within the same species. These markers show variations in DNA sequences that can be used to distinguish one individual from another.

What are two essential types of nucleotide sequences found in transposon DNA?
Terminal inverted repeats (TIRs) and target site duplications (TSDs) are two essential types of nucleotide sequences found in transposon DNA. TIRs are short inverted sequences found at each end of the transposon, while TSDs are short repeated sequences created upon insertion of the transposon into the target DNA.
How is a SNP identified in an alignment?
A SNP (Single Nucleotide Polymorphism) is identified in an alignment by comparing the DNA sequences of different individuals or species. A SNP is a variation at a single nucleotide position in the DNA sequence. By aligning the sequences and looking for differences at specific positions, researchers can identify SNPs.
How is the hereditary information in DNA coded and passed generation to generation?
as nucleotide base sequences that make up genes
Are the two strands of DNA identical to each other?
No, the two strands of DNA are not identical to each other. They are complementary and have opposite sequences of nucleotide bases.
What are the differences between amino acid sequence and nucleotide sequence in terms of their composition and function?
Amino acid sequences are made up of building blocks called amino acids, while nucleotide sequences are made up of building blocks called nucleotides. Amino acid sequences determine the structure and function of proteins, while nucleotide sequences determine the genetic information in DNA and RNA.
What reflect exact nucleotide sequences of active DNA?
The exact nucleotide sequences of active DNA refer to the specific arrangement of adenine (A), thymine (T), cytosine (C), and guanine (G) bases that make up the functional regions of DNA involved in gene expression, replication, and other cellular processes. These sequences can vary between different genes and cell types, and play a critical role in determining how DNA is transcribed into RNA and ultimately translated into proteins.
Two pieces of DNA can be joined to form a single piece only if they?
Have single chain ends with complementary nucleotide sequences
