6. What is the purpose of DNA replication? (“To make more DNA” would not be a complete answer.) 7. Summarize the process of DNA replication by using the following terms: semiconservative replication, replication fork, template, nucleotide, primer, origin of replication, leading vs. lagging strand, DNA polymerase, helicase, DNA ligase, gyrase. (Know what each term means.) 8. Why are some portions of DNA strands synthesized discontinuously? 9. Summarize the process of RNA synthesis (transcription) by using the following terms: promoter, RNA polymerase, rRNA, mRNA, tRNA, terminator, template, coding strand. (Know what each term means.) 10. Summarize the process of protein synthesis (translation) by using the following terms: genetic code, ribosome, mRNA, protein, amino acid, tRNA, codon, anticodon, start codon, stop codons, polypeptide. (Know what each term means.)
Explanation / Answer
6. What is the purpose of DNA replication? (“To make more DNA” would not be a complete answer.)
The main importance of DNA replicaiton is to maintain the stability of chromosome number or ploidy during the cell division of the organims. The DNA replication occurs during the S phase of the meiosis or mitosis. During this S phase due to DNA replication the chromatid number will be doubled, as during the division phase due to segregation the number will be reduced to half and it helps to maintain the same ploidy or same chromosome number.
