Transcription A

Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries the genetic instructions from DNA to the ribosome, where proteins are synthesized.

Front

What is the primary function of tRNA?

Back

tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during protein synthesis, matching them to the coded message in mRNA.

Front

What is rRNA?

Back

rRNA (ribosomal RNA) is a component of ribosomes, which are the cellular structures where protein synthesis occurs.

Front

What is transcription?

Back

Transcription is the process by which the genetic code from DNA is copied into a complementary strand of mRNA.

Front

What is the role of uracil in RNA?

Back

Uracil is one of the four nitrogenous bases in RNA, replacing thymine found in DNA.

Front

How does RNA differ from DNA in terms of structure?

Back

RNA is usually single-stranded, while DNA is double-stranded.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA and RNA corresponds to the sequence of amino acids in proteins.

Front

What is the process of translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is decoded to produce a specific polypeptide or protein.

Front

What are the three main types of RNA involved in protein synthesis?

Back

The three main types of RNA are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What is the role of RNA polymerase in transcription?

Back

RNA polymerase is the enzyme that synthesizes RNA by unwinding the DNA and adding complementary RNA nucleotides.
