BIOB 375 1st Edition Lecture 13 Outline of Last Lecture I. Review Outline of Current Lecture II. Cell Divisionsa. Growthb. ReproductionCurrent LectureMost common missed questions:4. Replication, transcription and translation are three essential biological processes in living organisms. What is false:- DNA replication is semi-conservative, so only one strand is being replicated. 5. The DNA sequence that encodes which of the following parts of a mature mRNA must be found within as exon of a eukaryotic gene?- The AUG start codon8. The first 10 nt of DNA in 5’ to 3’ direction after replication are:- (A)Lecture 11: Cell Divisions- Living organisms are capable of growth and reproduction o Growth In size In numbero Reproduction Asexual reproduction Sexual reproduction In Bacteria:- Growtho Only size- Reproductiono Asexual reproductionIn Eukaryotes:- Growtho In sizeo In number – Through cell division (Mitosis)- Reproductiono Asexual reproduction – Mitosiso Sexual reproduction - MeiosisReproduction of eukaryoteSexual reproduction MeiosisAsexual reproduction MitosisSexual reproductionIn plants:- Anthers (male) part- Stigma (female) partSexual reproduction seedsAsexual reproduction potato In animals:Sexual reproduction babyAsexual reproduction cloning Somatic cells – normal cellsGametic cells – reproductive cellsThree fundamental events in cell division:- Growth- Receiving signal for dividing 1. Synthesize enzymes for DNA replication 2. DNA replication 3. Check for the accuracy of DNA replication - Damaged cell will degrade and healthy cell will go on to replicate and complete the
