Q5: Transcription is when DNA is used to make which molecule?

DNA

RNA

Amino Acids

Protein

Q6: Translation is when RNA is used to make which molecule?

DNA

RNA

Amino Acids

Proteins

Q7: What is the role of ribosomes?

To store genetic information.

To produce glycolipids.

To synthesize proteins.

To hydrolyze waste materials.

Q8: Suppose a cell had normal messenger RNA (mRNA) but no functioning transfer RNA (tRNA). How would this affect translation?

The cell would be able to make mRNA but would not be able to make amino acids.

The cell would not be able to synthesize proteins because it would not be able to assemble ribosomes.

The cell would be able to carry instructions to ribosomes for coding proteins, but would not be able to synthesize proteins.

The cell would be able to transcribe DNA to RNA but would not be able to carry instructions to ribosomes for coding proteins.

Q9: Read the paragraph about the different types of RNA. In the process of transcription, DNA is used as a template for making mRNA in the (a) .The mRNA moves to the cytoplasm , where (b) brings in amino acids to the ribosomes, which contain (c) .
