    flow of information is depicted as: DNA --> RNA --> protein. Both DNA and RNA can be replicated (i.e. DNA is synthesized from DNA‚ and RNA from RNA). RNA can be made or transcribed from DNA. It is called transcription since the same type of "language" is used in DNA and RNA -- i.e. nucleic acids. In some cases RNA may be used to make DNA (i.e. "reverse transcription") using a particular enzyme called reverse transcriptase. Protein is synthesized from RNA by translation. It is called translation‚ because

    Answer the following in at least 100 words: 1. Describe the structure of DNA. ➢ DNA is a nucleic acid‚ which consist of long chains (polymers) of chemical units (monomers) called nucleotide. A molecule of DNA contains two polynucleotides‚ each a chain of nucleotides. Each nucleotide consists of a nitrogenous base‚ a sugar‚ and a phosphate group. Each DNA strand serves as a mold‚ or template‚ to guide reproduction of the other strand. There are four different types of nucleotides found in DNA

    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
