Sophia - Human Biology - Unit 6 Challenge 1
1 — Structure of DNA and Chromosomes
Understand the structure of DNA.
If one strand of a DNA double helix has bases "ATCCGC," what bases are on the
other strand of the helix?
a.) GCCGAT
b.) GCTTAT
c.) TAGGCG
d.) TTCCGA
2 — Mitosis
Identify various components of mitosis
In which phase of mitosis do the chromosomes line up and become attached to
spindle fibers?
a.) Prophase
b.) Telophase
c.) Metaphase
d.) Anaphase
3 — Meiosis and Genetic Variability
Understand the process of meiosis and how it results in genetic variability
Which of these is true about meiosis?
a.) Meiosis occurs in all type of cells.
b.) Meiosis causes an increase in the chromosome number.
c.) Meiosis results in the formation of haploid cells.
d.) Daughter cells are identical to the parent cell.
4 — DNA Replication
Understand the process of DNA replication
What is a change in a gene's sequence called?
a.) DNA replication
b.) Gene mutation
c.) Semiconservative replication
d.) DNA polymerases
