Question

Which type of RNA carries the genetic information from DNA to the site of protein synthesis? mRNA rRNA tRNA

Answer 1

i wanna say its tRNA?

Answer 2

rRNA
Ribosomal RNA (rRNA) along with ribosomal proteins make up ribosomes, the "workbenches" on which polypeptides (proteins) are synthesized. It turns out that it is actually rRNA, and not a protein, in the large subunit of the ribosome that performs the peptidyl transferase function of linking amino acids together via peptide bonds. In eukaryotes, the genes coding for rRNAs are located in the nucleolus of the nucleus. A ribosome has 3 binding sites: an A (aminoacyl) site, a P (peptidyl) site, and an E (exit) site.

mRNA
The message carrying the information needed to make a particular polypeptide exists in the mRNA molecule. It binds with a ribosome and the ribosome starts reading it one codon - 3 consecutive mRNA bases - at a time. Each of the possible 64 codons codes for a particular amino acid, or for a release factor (in which case it is a STOP codon). So the order of bases in the mRNA specifies the order in which amino acids are linked together to form a polypeptide.

tRNA
A tRNA molecule has 2 main sites. At one end it has an amino-acid attachment site and on the opposite end it has a 3-base anticodon. An enzyme (an aminoacyl-tRNA synthetase) recognizes the type of tRNA and attaches the appropriate amino acid to it, at which point the tRNA is said to be charged. Charged tRNA molecules "bump into" the empty ribosome A site, but only if there is a complementary match between the mRNA codon associated with that site and the anticodon on the tRNA does the charged tRNA dock.

Answer 3

Which do u think now?

Answer 4

im thinkin its m? Im not positive... :\ its m or t.

Answer 5

Let me make it simple

Answer 6

im thikin its m now haha

Answer 7

mRNA - messenger RNA- Acts as a messenger

tRNA - Transfer RNA

rRNA - Ribosomal RNA

Answer 8

Now Which ?

Answer 9

messenger carries message from DNA

Answer 10

and its transporting so it is t

Answer 11

Hmm we have a smart person here :D

Answer 12

Good Job

Answer 13

haha ^_^
I feel like shouting katie deserves a cookie xD

Answer 14

It wasnt t. must have been m since it has nothin stated for ribosomes..

Answer 15

Yea M is a messnger mRna

Answer 16

Sorry bout that

Answer 17

its ok i have another chance to retake it:) thanks for helping me two or three times now carolina4567!

Answer 18

Np anytime
