WebAs DNA polymerases can only extend a DNA strand in a 5′ to 3′ direction, different mechanisms are used to copy the antiparallel strands of the double helix. In this way, … WebA complementary DNA (cDNA) probe can be generated from a specific mRNA. The mRNA, encoding a specific protein, is a template. By the action of reverse transcriptase and DNA polymerase, a cDNA is formed that can be used as a probe to hybridize with a specific gene sequence ( Fig. 10.49 ). Figure 10.49. WebSince RNA is transcribed from DNA, the DNA sequence will determine the sequence of RNA, the codons, and ultimately what amino acids come together to form a protein. If a DNA sequence (template strand) goes CTTAGG, the corresponding RNA will read GAAUCC. In this sequence there are two codons: GAA followed by UCC, which will code for amino … ttd devasthanam booking
