Chargaff’s Rule - Each species has identical amounts of Adenine and Thymine bases in their DNA‚ and also identical amounts of Guanine and Cytosine‚ A = T; G = C. - A + G = T + C • RNA (Ribonucleic Acid) - It is a single stranded molecule. - It can be found in nucleus as well as cytoplasm. - There are three types of RNA: mRNA‚ tRNA‚ and rRNA - The

Transcriptomics: Past and Present Introduction The transcriptome is defined as the complete set of transcripts in a cell‚ and their quantity‚ for a specific developmental stage or physiological condition. It includes all the mRNA transcripts in a cell‚ reflecting genes that are actively expressed at any given time. An understanding of the transcriptome is essential for interpreting the functional elements of the genome and the development and disease. The key aims of transcriptomics are: cataloguing

To reduce contaminating genomic DNA from RNA‚ proper RNA isolation and cDNA synthesis procedures need to follow .The supernatant biofilm mass was pelleted after centrifugation at 18‚400 g for 20 min at 40c . The supernatant is discarded and double volume (1ml) of RNA protect bacterial reagent (qiagen) was added to each pellet and re-suspended and transferred to 1ml tube. The mixture was mixed immediately

interacts with Thymine‚ while Cytosine interacts with Guanine. RNA -RNA‚ also known as ribonucleic acid‚ is single-stranded. -An RNA nucleotide is structurally similar to that of a DNA nucleotide‚ but it contains a ribose sugar instead of a deoxyribose sugar. -In addition‚ RNA has the nucleotides Adenine‚ Cytosine‚ Guanine and Uracil. Thymine is NOT present in RNA. -Adenine pairs with Uracil‚ while Cytosine pairs with Guanine. -RNA is usually used as a “temporary molecule”‚ meaning that it is usually

primary judge stated the question at [1]‚ as whether a patent may be granted for a claim that covers naturally occurring nucleic acid – either DNA or RNA – that has been “isolated”. His Honour said‚ that in this context‚ the word “isolated” implies that the naturally occurring nucleic acid found in the cells of the human body‚ whether it be DNA or RNA‚ has been removed from the cellular environment in which it naturally exists and separated from other cellular components also found
