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.
What else can I help you with?
Does running blast using nucleotides or amino acids yield more specific matches?
Running BLAST using amino acids generally yields more specific matches compared to using nucleotides. This is because protein sequences are shorter and more conserved than nucleotide sequences, allowing for clearer identification of homologous proteins. Additionally, amino acid sequences are less prone to variation than nucleotide sequences, which can have multiple codons for the same amino acid, leading to a higher likelihood of identifying functionally related proteins.
What genes code for the same character?
The genetic codeThe genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated intoproteins (amino acid sequences) by living cellsThose genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.Each nucleotide sub-unit consists of a phosphate, deoxyribose sugar and one of the 4 nitrogenous nucleotide bases.
Which sample sequences do not match the tigers sequence Where in the first 40 base pairs do the non-matching sequences differ from the tigers Refer to each non-matching nucleotide by its number in?
To determine which sample sequences do not match the tiger sequence, you would need to compare each nucleotide in the first 40 base pairs of the samples against the corresponding positions in the tiger sequence. Any position where the nucleotide differs indicates a non-matching sequence. For example, if the tiger sequence has an 'A' at position 5 and a sample has a 'C' at the same position, then that sample does not match the tiger sequence at position 5. You would list all differing positions to identify the non-matching sequences.
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.
Why does not the substitution of nucleotides in the mouse change its phenotype or physical characteristics?
The substituted nucleotide has the same directions as the original nucleotide.
Do all living animals have the same nucleotide code?
Yes, all living animals share the same nucleotide code, known as the genetic code. This code consists of sequences of nucleotides in DNA and RNA that dictate how proteins are synthesized. While the code is universal, variations in nucleotide sequences lead to the diversity of life, allowing for different traits and characteristics among species.
Two nucleotide sequences found in two different species are almost exactly the same This fact suggests that these two species probably?
May have similar evolutionary histories

How does each new nucleotide chain compare to the one on which it was formed?
The nucleotide sequences in the two chains of a DNA molecule are complementary.This means that A (adenine) in one chain always binds to T (thymine) in the other, and C (cytosine) always binds to G (guanine).So if the sequence in one chain is:AATCTGGAthe complementary sequence in the other chain will be:TTAGACCT
The change that is not a physical change is?
The substituted nucleotide has the same directions as the original nucleotide.

Quantifier sequences Do the following two statements mean the same thing?
To determine if the following two statements mean the same thing, you would need to offer the quantifier sequences. Then, you could compare the sequences to determine if they are the same.
Why does not the substitution of nucleotides in the mouse change its phenotype or physical characteristics?
The substituted nucleotide has the same directions as the original nucleotide.
Can a codon contain two of the same nucleotide bases?
no
What stays the same in a nucleotide?
the word it doesnt go capital or lowercase unless its in the begining of the sentence.
