NU 318 - Genetics Questions and
Correct Verified Answers
Transcription in Protein Synthesis
✓ Transcription is the process by which DNA is copied (transcribed) to mRNA,
which carries the information needed for protein synthesis.
Where are majority of a cell's DNA located?
✓ Nucleus
What is Mitosis?
✓ Cell Division: there is a duplication of a parent cell
✓
✓ Creates 2 new daughter cells that are identical to each other & parent cell
Translation in Protein Synthesis
✓ reading the mRNA codons to make proteins; occurs on the ribosomes, using
mature RNA, replacing thymine w/ uracil for the mRNA to be able to leave the
nucleus
Post-Translocation Modification in Protein Synthesis

✓
Four Bases that present in DNA
✓ 1. Adenine (A)
✓ 2. Thymine (T)
✓ 3. Cytosine (C)
✓ 4. Guanine (G)
✓ A+T
✓ C+G
What is a chromosome?
✓ -A complex of protein & nucleic acids in which an unbroken double helix of DNA
is tightly wound
✓ -temporary structure that is a large chunk of DNA containing genes
✓
✓ 22 pairs = Autosomes
✓ 1 pair of sex chromosomes
✓
✓ 46 individual chromosomes
What is Apoptosis?
✓ knowing when to take a cell out of the "workforce"

What is a telomere?
✓ Protects the end of a chromosome
Chromosome Structure/Shapes
✓ -2 sister chromatids attached by a centromere; identical DNA
✓ -complex of protein and nucleic acid in a double helix DNA tightly wound
✓
✓ Shapes:
✓ 1. Metacentric: X shaped, centromere in the middle (1, 3, 16, 19, 20)
✓ 2. Submetacentric: Arms lengths unequal, "L shape"
✓ 3. Acrocentric: the P short arm (13, 14, 15, 21, 22) P arm carries very little genetic
material since being short
Chromosome Formation
✓ -During cellular division chromatin condenses or coils to form rod like
chromosomes
✓ -Prophase
Chromosome Inheritance
✓
Helicase enzyme
