LEAP Biology I

Deoxyribonucleic Acid (DNA) is composed of-

• Carbon, Hydrogen, Potassium

• Sugar, Phosphate, and Nitrogen Bases

• Amino Acids, Proteins,

• Phospholipids

One half of the DNA molecule is copied into mRNA during-

• Cellular Respiration

• Translation

• Transcription

• Photosynthesis

After transcription, mRNA leaves the nucleus and meets up with the ribosome in the-

• Cytoplasm

• Vacuole

• Mitochondria

• Plasma Membrane

In the ribosome, the mRNA pairs with its corresponding nitrogen base pair on the-

• Nucleus

• Amino Acid

• RNA Polymerase

• tRNA

tRNA carries ________ to the ribosome to build a protein.

• Lipids

• Carbohydrates

• Amino Acids

• Nucleic Acids

All cells in the body contain the same DNA, but not all of the genes are expressed.

• True

• False

Each specialized cell has different _____ that are expressed, which allows them to look and function different.

• Genes

• Phenotype

• Homozygous

• Nucleus
