Q

Messenger RNA

A

Messenger RNA brings the DNA code from the nucleus to the ribosomes. This code determines the amino acid sequence for a specific protein.

17
Q

transcription

A

the process of making messenger RNA

Q

the process of making messenger RNA

A

transcription

19
Q

what unzips a portion of DNA

A

RNA polymerase

20
Q

RNA polymerase

A

what unzips a portion of DNA

21
Q

what happens after the RNA forms

A

mRNA leaves the nucleus and goes to the ribosome

22
Q

anticodon

A

a series of 3 tRNA

23
Q

codon

A

a series of 3 mRNA

24
Q

what does tRNA do after mRNA is formed

A

Transfer RNA in the cytoplasm of the cell carries specific amino acids to the messenger RNA at the ribosome.

25
Q

What happens after tRNA carries amino acids to mRNA

A

tRNA binds to a codon on mRNA and link together to form polypeptides

26
Q

What happens after tRNA and mRNA bond

A

tRNA releases its amino acid and leaves to search for another amino acid
