DNA and RNA Review

Front

What is the role of Transfer RNA (tRNA) in protein synthesis?

Back

tRNA matches to the mRNA code and connects the corresponding amino acid to a growing protein chain.

Front

What makes up the 'rungs' (steps) of the DNA ladder?

Back

The rungs of the DNA ladder are made up of nitrogen bases.

Front

What is the process of making a messenger RNA (mRNA) molecule called?

Back

The process is called transcription.

Front

Where is mRNA found in the cell?

Back

mRNA is found in the nucleus before it is transported to the ribosome.

Front

What base does RNA have instead of thymine?

Back

RNA has uracil instead of thymine.

Front

What are the building blocks of DNA and RNA?

Back

The building blocks are nucleotides.

Front

What are the three main components of a nucleotide?

Back

A nucleotide is made up of a sugar, a phosphate group, and a nitrogen base.

Front

What is the function of messenger RNA (mRNA)?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is the process of translating mRNA into a protein called?

Back

The process is called translation.
