A
Non-sex chromosomes.
2
Q
How are autosomes different from sex chromosomes?
A
They are homologous.
3
Q
Reverse transcriptase produces…
A
cDNA (complementary DNA).
4
Q
What are homologous chromosomes?
A
Chromosomes which have the same gene sequence (and length, loci and centromere location, shape) and which pair up in meiosis.
5
Q
When graphing bacterial populations, we often use logarithmic graphs. What does log ₁₀ ⁽ˣ⁾ mean?
A
log ₁₀ ⁽ˣ⁾ means 1x10 ˣ.
