ANSWERS & COMPREHENSIVE REVIEW
what happens in each stage of mitosis - ANS ✔✔interphase than PMAT
Interphase (Mitosis) - ANS ✔✔cell is preparing itself
Anaphase (Mitosis) - ANS ✔✔Chromosomes split apart and are pulled to opposite ends of cells
Telophase (Mitosis) - ANS ✔✔Nuclear membrane reforms
Metaphase (Mitosis) - ANS ✔✔all 46 chromosomes align in the center of the cell
Prophase (mitosis) - ANS ✔✔sister chromatids are forming and duplicating
Where are anticodons present - ANS ✔✔tRNA anticodon
Is there any change in the chromosome number in the daughter cell as compared to the
parental cell - ANS ✔✔the parental cell has 46 while the daughter cell only has 23
What are homologous chromosomes? - ANS ✔✔Two chromosomes with the same set of genes,
in the same sequence, sometimes with different alleles
Trait - ANS ✔✔A characteristic that an organism can pass on to its offspring through its genes.
Allele - ANS ✔✔Different forms of a gene of the same trait
, Dominant - ANS ✔✔capital letter
Recessive - ANS ✔✔lower case letter
Ocular - ANS ✔✔Eyepiece of a microscope
Arm - ANS ✔✔the vertical support leading upward from the base to the body tube
Correlation between field of view and magnification - ANS ✔✔as magnification increases the
diameter of the field it decreases in proportion
What is the field of view? - ANS ✔✔the diameter of the circle that you can see through the
microscope
Where are codons present - ANS ✔✔mRNA
What is a codon? - ANS ✔✔a sequence of three nucleotides that together form a unit of genetic
code in a DNA or RNA molecule.
In prophase 1 of meiosis, what happens? - ANS ✔✔Homologous, chromosomes pair up
Objectives - ANS ✔✔the three lenses on the revolving nosepiece
Base - ANS ✔✔stand that supports the microscope and contains the light
What is translation? - ANS ✔✔the decoding of an mRNA message into a protein
