5.2a PRACTICE - Transcription (DNA to RNA)

Front

What is the main difference between RNA and DNA?

Back

RNA contains uracil and ribose, while DNA contains thymine and deoxyribose.

Front

How many nucleotides are needed to code for one amino acid?

Back

3 nucleotides.

Front

Where does the process of transcription occur in a cell?

Back

Transcription takes place in the nucleus.

Front

What is the process called that copies DNA in the nucleus?

Back

Replication.

Front

Is RNA single-stranded or double-stranded?

Back

RNA is single-stranded.

Front

What are the three main types of RNA?

Back

mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What is the role of mRNA in transcription?

Back

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

Front

What is the function of tRNA?

Back

tRNA transports amino acids to the ribosome during protein synthesis.

Front

What is the role of rRNA?

Back

rRNA is a component of ribosomes and helps in the assembly of amino acids into proteins.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.
