Has anyone here done this before? If so, kit recommendations and protocol? Any help would be awesome. Thanks!
cDNA, or complementary DNA, is a synthesized version of DNA that contains only the coding sequences of genes. It is made from mRNA using the enzyme reverse transcriptase. Unlike DNA, cDNA does not contain introns or non-coding regions.
In order to translate a cDNA sequence into a protein sequence, the cDNA is first transcribed into mRNA. The mRNA is then read by ribosomes, which use the genetic code to assemble amino acids into a polypeptide chain. This chain is then folded into a protein.
cDNA is important in genetic research because it allows scientists to study only the coding regions of genes, which are responsible for the production of proteins. This can help identify genes that are expressed in certain tissues or diseases, and can also be used to produce recombinant proteins for various applications.
Yes, a cDNA sequence can be used to predict the structure of a protein. This is because the sequence of amino acids in a protein is determined by the sequence of nucleotides in the cDNA that codes for it. By using computational methods, scientists can predict the folding and structure of a protein based on its amino acid sequence.
One limitation of using cDNA is that it only represents the coding sequences of genes, which means that it does not capture any potential regulatory regions or non-coding RNA sequences. Additionally, cDNA sequences may not accurately represent the entire transcriptome of an organism, as some mRNA molecules may not be efficiently converted into cDNA. Finally, cDNA sequences may contain errors due to reverse transcriptase activity or PCR amplification.
