What is the complementary DNA strand of ATG?

Back

TAC

Front

What is diffusion?

Back

Diffusion is the movement of molecules from areas of high concentration to areas of low concentration until equilibrium is reached.

bb

Front

What is the complementary RNA sequence for the DNA sequence ATTCGT?

Back

UAAGCA

Front

What is the correct order of biological organization?

Back

cell-tissue-organs-organ systems-organism

Front

Define complementary base pairing in DNA.

Back

Complementary base pairing refers to the specific pairing of nitrogenous bases in DNA: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating messenger RNA (mRNA) into amino acid sequences.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits or characteristics.

Front

What is equilibrium in the context of diffusion?

Back

Equilibrium is the state reached when the concentration of molecules is equal throughout a space, resulting in no net movement.

Front

What is the function of mRNA in cells?

Back

mRNA (messenger RNA) carries genetic information from DNA to the ribosome, where proteins are synthesized.
