how is the nucleotide sequence in the mRNA translated into polypeptide sequence?

Answer 1

The messenger RNA interacts with ribosomes. Transfer RNA molecules (tRNA) each carrying a specific amino acid come into the the ribosome. The anticodon of the tRNA binds to the three-base codon of the mRNA to insure that the correct tRNA is in place. Then, the amino acid bound to the tRNA is linked to the next amino acid.

There are a lot of sites online with digrams and explanations of the translation process. Just google "translation ribosome mRNA" and you'll find some.

Answer 2

mRNA is transcribed by protein synthesis in the nucleus by using one comlimentary strand of DNA. The transcribed mRNA , through the nuclear pores enters the cytoplasm where translation takes place[message of DNA to synthesise proteins is brought into action.It has three steps: initiation, élongation and termination. ininitiation protein synthesis begins at initiation codon AUG by attracting corresponding anticodon UAC.In elongation the ribosome shifts one codon at a time and adjacent codons attract their corresponding anticodons.this contrinues till by chance it encounters the stop codon UAA and the process ends.In this way the nucleotide sequence in mRNA is translated into polypeptide sequence

Answer 3

ok, there is an trouble-free way and a protracted thank you to make your ideas up. permit's start up with the easy. at the start, permit AAA-GGG-CCC-UUU be our amino-acid chain. Hypothetical, yet trouble-free to do. bear in mind, purely DNA has the backside THYMINE. RNA and proteins have URACIL rather of thymine, so as a result, Uracil pairs with Adenine outdoors the nucleus (ie. DNA). So, if AAA-GGG-CCC-UUU, their complementary bases are the DNA codes. Protein: AAA-GGG-CCC-UUU DNA: TTT-CCC-GGG-AAA Now, for the good way... permit's start up with DNA first: DNA: TTT-CCC-GGG-AAA messenger RNA comes into the nucleus to repeat that code, yet makes use of uracil to pair up with adenine. DNA: TTT-CCC-GGG-AAA mRNA: AAA-GGG-CCC-UUU mRNA takes its codes to the ribosome, the place circulate RNA (tRNA) makes anti-codons: mRNA: AAA-GGG-CCC-UUU tRNA: UUU-CCC-GGG-AAA amino acids that are complementary to the codons of the tRNA get linked, as a effect forming a protein chain tRNA: UUU-CCC-GGG-AAA Protein: AAA-GGG-CCC-UUU
