DNA and RNA

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) carries amino acids to the ribosome, where proteins are synthesized.

Front

What is the correct order of DNA replication?

Back

1. DNA unzips 2. DNA unwinds 3. The bases attach from a supply in the cytoplasm 4. Sugar and phosphate groups form the side of each new strand.

Front

What shape does a DNA molecule have?

Back

A DNA molecule has a double helix shape.

Front

Which organisms contain DNA?

Back

All living organisms, including animals, plants, and bacteria, contain DNA.

Front

What is the difference between DNA and RNA in terms of nitrogenous bases?

Back

DNA contains thymine (T), while RNA contains uracil (U).

Front

What is the sugar component of DNA?

Back

The sugar in DNA is deoxyribose.

Front

What is the sugar component of RNA?

Back

The sugar in RNA is ribose.

Front

Where is DNA primarily located in eukaryotic cells?

Back

In eukaryotic cells, DNA is primarily located in the nucleus.

Front

Where is RNA primarily located in eukaryotic cells?

Back

In eukaryotic cells, RNA is primarily located in the cytoplasm.

Front

What is the role of rRNA in protein synthesis?

Back

rRNA (ribosomal RNA) is a component of ribosomes and helps facilitate the translation of mRNA into proteins.
