Protein Synthesis and RNA

Front

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

Back

RNA contains uracil in place of thymine.

Front

What is ribosomal RNA (rRNA)?

Back

Ribosomal RNA is a form of RNA that makes up a ribosome and catalyzes protein synthesis.

Front

How many strands does RNA have?

Back

RNA has one strand.

Front

What type of RNA carries the DNA message out of the nucleus to the ribosomes?

Back

mRNA (messenger RNA) carries the DNA message out of the nucleus to the ribosomes.

Front

Which of the following is a type of RNA? mRNA, tRNA, rRNA, or All of these?

Back

All of these are types of RNA.

Front

What is the primary function of mRNA?

Back

The primary function of mRNA is to carry the genetic information from DNA to the ribosomes for protein synthesis.

Front

What does tRNA do in protein synthesis?

Back

tRNA (transfer RNA) carries amino acids to the ribosome and matches them to the coded mRNA message.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where protein synthesis occurs, translating mRNA into a polypeptide chain.

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is the role of RNA polymerase?

Back

RNA polymerase is the enzyme that synthesizes RNA from a DNA template during transcription.
