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

D. is transcribed to RNA that is always subsequently translated to a polypeptide. E. can always be replicated by enzymes produced within that cell or virus. Answer: B 3. Which of the following is not a possible component of a DNA nucleotide? A. adenine

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
