Answer #1

1) The pink structure is DNA , Blue is RNA and green is protein. The DNA and RNA plays an important role in encoding the genetic information of an individual . There is no role of protein in encoding the genetic information as the protein is a product of genetic information. Both RNA and protein acts as an enzymes and are involved in the catalytic reactions . The DNA do not takes part in the catalysis reaction. RNA enzymes are known as ribozymes . The building blocks of DNA and RNA are nucleotides where the protein is made up of amino acids . DNA is made up of four types of nucleotides that is adenine , guanine , cytosine and thymine . Whereas RNA is made up of adenine , guanine , cytosine and Uracil . Protein is made up of 20 different type of amino acids. DNA is double stranded molecule . RNA is single stranded and Protein is also single stranded. The structure of DNA is double standard. The structure of RNA is different four different type of RNA . Protein has a very complex structure which can be categorised under primary secondary tertiary and quaternary . The DNA is extremely susceptible to degradation. There is variations in the degradation of RNA and protein. DNA has a repair mechanism whereas there is no mechanism of repair in RNA and protein. DNA is present in the nucleus . RNA present in both nucleus and cytoplasm . Protein is present throughout the cytoplasm . The process of formation of DNA is replication. The process of formation of RNA transcription. The process of formation of protein is translation .

    Regulation of Gene Expression in Eukaryotes In all organisms, certain genes are expressed at any given time while other genes are not. Both prokaryotes and eukaryotes regulate gene expression at the transcription stage. However the greater complexity of eukaryotic cells makes it possible for gene expression to be regulated at many other stages as well. The diagram below shows different stages at which gene expression may be regulated in eukaryotes. nucleus chro modifica anscription RNA processing cytoplasm degradation protein processing...
