DNA Only

What is the main role of RNA in protein synthesis?

Exist entire within the protected nucleus

Produce genetic information for the cell

Directly create proteins

Help transfer genetic material from the nucleus to the cytoplasm

Which of the following accurately describes the difference between transcription and translation?

In transcription, the genetic code of DNA molecule is first encoded. Translation is the process of converting DNA code into code that RNA can use.

In transcription, a double helix DNA molecule is split into two separate single strands. Translation is the process of joining each single DNA strand with a single strand of matching RNA.

In transcription, an amino acid chain is encoded in a DNA molecule. Translation is the process of turning the amino acids into nucleic acids in an RNA molecule.

In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. Translation is the process of creating an amino acid chain using the encoded messenger RNA.

A section of DNA strand has the sequence ACCGAGGTT. What is the sequence of an mRNA transcribed from this section of DNA?

UGG-CUC-CAA

ACC-GAG-GTT

TGG-CTC-CAA

ACC-GAG-GUU

What role does the RNA polymerase enzyme play in transcription?

Unwinds the DNA

Creates a complementary sequence of bases

Binds to the gene

Reads the bases in one of the DNA strands

Which amino acid would be transferred to the position of codon CAC?

Leucine

Histidine

Valine

Glycine

The biochemical process represented in the diagram is most closely associated with the cell organelle known as the

Chloroplast
