2. RNADuring protein synthesis certain specific regions of DNA (the genes) are copied into a polynucleotide of a chemically and functionally different type known as ribo nucleic acid.RNA is a nucleic acid polymer consisting of nucleotide monomers that acts as a messenger between DNA and ribosomes and is also responsible for making proteins out of amino acids.RNA is similar to DNA but containing ribose in place of deoxyribose and uracil in place of thymine.

25. HnRNA are immediate product of gene transcription. The nuclear product is heterogenous in size and is very large. 75% of hnRNA is degraded in the nucleus, only 25% is processed to mature mRNA

27. Functions of RNARNA is a nucleic acid messenger between DNA and ribosomes.It serves as the genetic material in some organisms (viruses).Some RNA molecules play an active role within cells by catalyzing biological reactions, controlling gene expression, or sensing and communicating responses to cellular signals.Messenger RNA (mRNA) copies DNA in the nucleus and carries the info to the ribosomes (in cytoplasm).Ribosomal RNA (rRNA) makes up a large part of the ribosome; reads and decodes mRNA.Transfer RNA (tRNA) carries amino acids to the ribosome where they are joined to form proteins.Certain RNAs are able to catalyse chemical reactions such as cutting and ligating other RNA molecules, and the catalysis of peptide bond formation in the ribosome; these are known as ribozymes
