Review<\/span><\/strong><\/p>\n

\u2022 DNA is made of nucleotides joined together to form a double helical structure.<\/p>\n

\u2022 Each strand contains the genetic code for the particular gene.<\/p>\n

\u2022 Different DNAs are responsible for the production of different proteins.<\/p>\n

How does DNA carry genetic information?<\/span><\/strong><\/p>\n

\u2022 The DNA molecule carries genetic information in the unique base-pairing and base sequences of the gene.<\/p>\n

\u2022The genetic information, which codes for characteristics of an organism, results from the sequence of nucleotides in the DNA, which make up units called genes.<\/p>\n

WHAT IS GENE EXPRESSION?<\/span><\/strong><\/p>\n

\u2022 The process of transferring the information encoded in a gene to its functional gene product.<\/p>\n

RNA processing in Eukaryotes<\/span><\/strong><\/p>\n

\u2022 Coding regions of eukaryotic gene are separated by sections of DNA that are not translated into proteins.<\/p>\n

DNA gene: Intronic and exonic DNA<\/strong><\/span><\/p>\n

\u2022 DNA sequences that does not code for proteins are called introns or intronic DNA.<\/p>\n

\u2022 DNA sequence that gives rise to a translated polypeptide sequence are called exons.<\/p>\n

Eukaryotic genomes<\/strong><\/span><\/p>\n

\u2022 Eukaryotic genomes contain a large amount of introns.<\/p>\n

\u2022 Introns were termed as \u201cjunk DNA\u201d and assumed to have no function. New evidence suggests that this DNA may encode a vast number of RNA molecules with regulatory functions.<\/p>\n

\u2022 An increase in complexity is associated with an increase in the proportion of nonprotein-coding DNA.<\/p>\n

\u2022 Intronic DNA may has a role in regulating genomic function.<\/p>\n
