Genetics & Molecular Biology

Question 1

DNA & RNA Basics

DNA

Answer 1

Double-stranded, contains A, T, C, G

Question 2

DNA & RNA Basics

RNA

Answer 2

Single-stranded, contains A, U, C, G

Question 3

Protein Synthesis

Transcription (in nucleus)

Answer 3

DNA -> mRNA

Question 4

Protein Synthesis

Translation (in ribosome)

Answer 4

mRNA -> Protein (tRNA helps by brining amino acids)

Question 5

Mendelian Genetics

Dominant vs. Recessive Traits

Answer 5

(e.g., Aa = dominant trait expressed)

Question 6

Mendelian Genetics

Punnett Squares

Answer 6

Predicts offspring genotype/phenotype ratios

Question 7

Mendelian Genetics

Incomplete Dominance

Answer 7

Blended traits (e.g., red + white = pink flowers)

Question 8

Mendelian Genetics

Codominance

Answer 8

Both alleles are expressed (e.g., AB blood type)
