Study Notes
Asexual Reproduction
- Asexual reproduction involves a single individual producing offspring.
- Produces genetically identical offspring, as seen in yeast cells.
Sexual Reproduction
- Sexual reproduction generates greater genetic variation in offspring due to unique gene combinations from both parents.
Gamete Formation
- Gametes are formed through meiosis, which produces haploid cells from diploid parental cells.
- Normal human gametes contain 23 chromosomes, one set of chromosomes.
- A diploid organism with 32 chromosomes produces gametes with 16 chromosomes.
Bacteria and Cell Division
- Bacteria replicate through binary fission, a method of simple cellular division.
- The first step in bacterial replication is DNA replication, ensuring each daughter cell receives a copy of the chromosome.
- Binary fission guarantees equal distribution of the parental chromosome to daughter cells.
Differences Between Prokaryotic and Eukaryotic DNA
- Prokaryotic DNA is typically circular, while eukaryotic DNA is linear.
- Prokaryotic cells have less DNA than eukaryotic cells and do not have a nucleus.
Sister Chromatids
- The DNA sequences in sister chromatids are identical, barring rare mutations, resulting from replication of a single DNA molecule.
- Cells replicate their entire chromosomal DNA only prior to division to ensure equal genetic material distribution to daughter cells.
