Question

Genes _______

are ribosomes

are mRNAs

code for proteins

are made of proteins

are traits

Answer 1

Option (c) Code for proteins is correct answer.

Gene :-
• Gene is functional unit of DNA segment which encodes for protein by gene expression process.
• In gene expression, gene or DNA encodes for mRNA in the step called transcription and this mRNA encodes for protein in the step called translation.
• Gene or DNA is formed by nucleotide monomers and nucleotide monomers are formed by deoxyribose sugar, nitrogenous base and phosphate group.

Other options -
• Ribosome is a cell organelle which is formed by RNA and protein and it helps in translation or protein synthesis process.
• mRNA is formed on gene sequence during transcription process.
• Traits are genetically determined characters. Each character has two traits - dominant and recessive. For example - in pea plants - height of plant is a character which has two traits - dominant trait is tall plant and recessive trait is dwarf plant.
