What else can I help you with?
What if we could see the individual nucleotide sequences of DNA?
You can see the nucleotide sequences in the DNA. It is called as DNA finger printing. It has got many applications in molecular biology.
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.
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.
What are repetitive DNA sequences in the ends of chromosomes called?
Telomeres
How man different possible base sequences are there in a nucleotide chain three nucleotides in length?
There are 64 (4^3) different possible base sequences in a nucleotide chain that is three nucleotides in length. This is because there are 4 possible nucleotide bases (A, T, C, G), and each position in the sequence can be occupied by any one of these 4 bases.

The set of three nitrogen bases on tRNA that is complementary to an mRNA codon is called?
These nucleotide sequences are called anticodons.
Nucleotide sequence that starts PCR processes?
Primer sequences

Telomeres
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 are three things that scientists use nucleotide sequences to determine?
punk

What is a telomer?
A telomere is a region of repetitive nucleotide sequences at the end of a chromosome that protects it from deterioration or from fusion with neighboring chromosomes. Telomeres shorten with each cell division, eventually contributing to cellular aging and senescence. They play a crucial role in maintaining genomic stability.
How are nucleotide sequences used to put organisms in evolutionary order?
When comparing nucleotide sequences in organisms, we find that the organisms that have less differences in their nucleotide sequences are closer related in the evolutionary tree. By this we mean that the common ancestor from which these two organisms evolved is more modern than the ancestor they might share with an organism that shows more difference in the DNA sequencing. Example: the chimps and humans share a common ancestor that is relatively modern because the difference in their nucleotide sequences is just about 1% but the differences between the nucleotide sequence of humans and fish shows lots of differences which shows their common ancestor y much older than the one with chimps.
What are the similarities between nucleotide and amino acid sequences?
Both nucleotide and amino acid sequences are essential components of genetic material. They both consist of building blocks that are arranged in a specific order to encode genetic information. Additionally, both sequences play crucial roles in the functioning and regulation of biological processes within cells.
