Ipaliwanag ang pagkakaiba ng DNA replication sa transcription. Ano ang layunin ng bawat proseso?

Answer (1)

Ang DNA replication at transcription ay parehong mahalagang proseso sa loob ng cell, ngunit magkaiba ang kanilang layunin at resulta.Ang DNA replication ay ang proseso kung saan kinokopya ang buong DNA molecule bago mag-cell division. Layunin nitong matiyak na ang bawat daughter cell ay magkakaroon ng kumpletong set ng genetic material. Nangyayari ito sa nucleus ng cell bago ang mitosis o meiosis. Sa replication, parehong strands ng DNA ay ginagamit bilang template, kaya’t nagkakaroon ng dalawang double-stranded DNA molecules—bawat isa ay may lumang strand at bagong strand (semi-conservative replication).Sa kabilang banda, ang transcription ay ang paggawa ng RNA (lalo na mRNA) mula sa DNA. Layunin nito na kopyahin ang bahagi ng genetic code na kakailanganin para sa paggawa ng protein. Sa transcription, isang strand lamang ng DNA ang binabasa at nagbubunga ito ng single-stranded mRNA. Nangyayari rin ito sa nucleus, ngunit ang mRNA ay lumalabas ng nucleus papunta sa ribosome upang maisagawa ang translation.Mas madali ring makilala ang kaibahan nila sa pamamagitan ng analogy: ang replication ay parang pag-photocopy ng buong libro (DNA), habang ang transcription ay parang pagkopya ng isang pahina ng recipe (gene) para lutuin ang isang ulam (protein).Sa buod, ang DNA replication ay para sa cell division at pagpasa ng genetic material, habang ang transcription ay para sa protein production sa tulong ng genetic instructions mula sa DNA.
