BISC-120 Exam 1 with correct answers
Where is DNA stored? - CORRECT ANSWERS ✔✔In the nucleus
Where does protein synthesis occur? - CORRECT ANSWERS ✔✔In
ribosomes
What is a genome? - CORRECT ANSWERS ✔✔All the DNA in one
cell
What does a genome consist of? - CORRECT ANSWERS ✔✔a
single DNA molecule (prokaryotic) or a number of DNA molecules
(eukaryotic)
What are chromosomes? - CORRECT ANSWERS ✔✔Coiled up
lengths of DNA molecules
What is mitosis? - CORRECT ANSWERS ✔✔Cell division that
generates new cells for growth and repair. The division of one cell
into two genetically identical daughter cells
,What is cytokinesis? - CORRECT ANSWERS ✔✔the cytoplasmic
division of a cell at the end of mitosis or meiosis, bringing about the
separation into two daughter cells.
How does DNA condense? - CORRECT ANSWERS ✔✔it wraps
around proteins called histones which condense into nucleosomes
that coils to make chromatin fiber that condenses into a
chromosome
What are sister chromatids? - CORRECT ANSWERS ✔✔joined
copies of the original chromosome
What is a centromere? - CORRECT ANSWERS ✔✔where the two
chromatids are most closely attached
How does a cell divide during mitosis? - CORRECT ANSWERS
✔✔Two sister chromatids of each duplicated chromosome separate
into two nuclei to make two chromosomes
What are gametes? - CORRECT ANSWERS ✔✔sex cells (sperm
and egg)
, What is meiosis? - CORRECT ANSWERS ✔✔a type of cell division
that results in non-identical four daughter cells each with half the
number of chromosomes of the parent cell, as in the production of
gametes
What is DNA? - CORRECT ANSWERS ✔✔a polymer of
nucleotides, each consisting of a nitrogenous base, a sugar, and a
phosphate group
What does thymine have that cytosine doesn't? - CORRECT
ANSWERS ✔✔a methyl group
what does guanine have that adenine doesn't? - CORRECT
ANSWERS ✔✔oxygen
What are the four nitrogenous bases? - CORRECT ANSWERS
✔✔Adenine, Thymine, Guanine, Cytosine
