• AGG GTA AGC CTT TAA

• TTU UUG GCT TUC CCT

• UUA AAG GCU UAC CCU

Which process produces mRNA from DNA?

• synthesis

• replication

• translation

• transcription

What amino acid sequence would be produced from the DNA sequence TAC CCC GCA AGT?

• Tyrosine - Proline - Alanine - Serine

• Methionine - Proline - Alanine - Serine

Prior to mitosis, a cell will undergo replication to copy the DNA before dividing. Which feature of DNA allows the replication to be semi-conservative and equip the new cell with an exact copy of the genes from the parent cell?

• DNA is single-stranded.

• DNA is transcribed into RNA before translation.

• Hydrogen bonds hold the strands closely together.

• Base pairing occurs between complementary strands.

Which statement correctly describes the relationship between genes, proteins, and traits?

• Genes are translated into proteins. The proteins are then transcribed into mRNA, which determines specific traits.

• Traits are translated into genes. The genes are then transcribed into mRNA, which determines specific proteins.

• Genes are transcribed into mRNA. The mRNA is then translated into proteins, which determine specific traits.

• Traits are transcribed into mRNA. The mRNA is then translated into genes, which determine specific proteins.

How is a segment of DNA copied to produce a molecule of mRNA?

• through reproduction

• through transcription

• through translation

• through cytokinesis

What carries the instructions for making amino acids in a protein?

• the nitrogen base on the tRNA

• the hydrogen bonding between nitrogen bases

• the sequence of nitrogen bases on the mRNA

• the nitrogen base bonding on the DNA molecule

A section of DNA has these bases: TAG CAG TAC. Which mRNA sequence is produced from this DNA section?

• ATC GTC ATG

• AUC GUC AUG

• AUG CUG AUC

• UTC GTC UTG

During translation, what does the tRNA deliver to the ribosomes?

• Amino acids

• DNA

• mRNA

• Proteins

Which best represents the sequence of bases on mRNA?

• A U C G

• A T U G

• A T C G
