BAC (Bacterial Artificial Chromosome) arrays are a type of DNA arrays. BAC arrays are usually used for a technique called array CGH (Comparative Genomic Hybridisation) which is used to identify gross deletions or amplifications in DNA (which for example is common in cancer). DNA arrays include BAC arrays but also oligo, cDNA, and promoter arrays. Oligo and cDNA arrays are typically used for gene expression analysis (looking to see how heavily expressed each gene is). Oligo arrays can also be used for SNP (single nucleotide polymorphism) analysis. Promoter arrays are used to identify transcription factor binding sites.
What else can I help you with?
How can foreign pieces of DNA be transfered into organisms?
By a vector such as a plasmid or by a BAC or YAC.
What is the difference between new and old DNA strands?
old is broken but new is not
What the difference between rna and dna in number of strands?
RNA is typically single-stranded, while DNA is double-stranded. RNA carries genetic information in some viruses and acts as a messenger between DNA and ribosomes during protein synthesis. DNA stores genetic information in most organisms and is the blueprint for the development, growth, and functioning of living organisms.
What is major difference between normal DNA helix and RNA helix?
DNA is double stranded while RNA only has one strand.
If you wanted to clone a sequence of DNA - 200 kb long - what vector should you use?
For cloning a 200 kb DNA sequence, a bacterial artificial chromosome (BAC) vector would be suitable due to its large insert capacity, stability, and ability to maintain large DNA fragments intact. BAC vectors can accommodate DNA inserts up to 300 kb in size, making them ideal for cloning large DNA fragments accurately.
Difference between the DNA and RNA?
the difference is that DNA is a double helix and RNA is a single chain
What is the difference between DNA and chromomatins?
Chromatins are made up of DNA strands
Are there any difference appearance between DNA from different cell?
No, there is no difference in appearance between DNA from different cells. DNA is a molecule that has a uniform structure regardless of the cell type it is found in. The only differences in DNA between cells come from variations in the sequence of nucleotides that make up the DNA.
How can foreign pieces of DNA be transfered into organisms?
By a vector such as a plasmid or by a BAC or YAC.
Which best describes a difference between transcription and DNA replication-?
Another answer could be that Transcription uses Uracil. This is the answer I got from Apex btw.
Is the DNA of a bull the same as the DNA of a lamb?
Nope. If they were the same, then there would no difference between a lamb and a bull.
What is the difference between virus and baterias?
Bacteria has both DNA and RNA where as Virus has either DNA or RNA
What is the difference between single gene DNA and repetitive sequences of DNA?
DNA is double Helix But A Gene is a part of that double helix.
What is the difference between a maternal and paternal DNA test?
A maternal DNA test compares the DNA of a child to that of their mother, while a paternal DNA test compares the child's DNA to that of their father. This helps determine biological relationships between individuals.
Difference between Z-DNA and B-DNA?
B DNA is the normal kind where it twists in what is called a right hand fashion. Z DNA is twisted in the opposite direction.
The difference between prokaryotic and eukaryotic DNA?
The difference is that eukaryotic DNA is organized into a well defined nucleus and prokaryotic DNA is not. An example of a prokaryote is bacteria (or a bacterium). Humans and fungi are eukaryotes. Prokaryotes also do not have introns (DNA that is not expressed), while Eukaryotes do.
What is the difference between ribonucleaic and deoxyribonucleaic acid?
No oxygen on the second carbon of the deoxyribose sugar used in DNA. That is the only difference between ribose and deoxyribose sugars. And, of course RNA is single stranded and has catalytic properties DNA does not have. DNA is strictly a storage of information molecule.
