What does tRNA bring amino acid to the nucleus or ribosomes?
tRNA brings the complementary base pair to the mRNA already in place. The complementary base pair codes for a certain amino acid. So tRNA does bring the amino acids to the ribosome by bringing the correct code in the sequence to make a protein.
How do ribosomes make proteins?
Ribosomes make proteins by reading messenger RNA (mRNA) and using transfer RNA (tRNA) to link together amino acids in the correct order. This process occurs in two main stages: translation and elongation. Ribosomes are responsible for coordinating the interaction between mRNA and tRNA to assemble the amino acids into a protein chain.
How is the nucleotide seguence in the mRNA translated into a polypeptide sequence?
mRNA contains codons that correspond to specific amino acids. During translation, ribosomes read the mRNA sequence and match each codon with its corresponding tRNA anticodon, which carries the specific amino acid. This process continues until a stop codon is reached, resulting in the formation of a polypeptide chain.
Which two structures are first to combine in translation?
The small ribosomal subunit and the initiator tRNA molecule are the first two structures to combine in translation. The initiator tRNA molecule carries the amino acid methionine, which is the first amino acid in the polypeptide chain.
What two processes must occur to get from a gene to a protein?
The two processes that must occur are transcription and translation. Transcription involves the synthesis of messenger RNA (mRNA) from the DNA template in the nucleus, while translation takes place in the cytoplasm and involves the synthesis of a protein based on the mRNA sequence.
What types of RNA are present in protein synthesis?
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA) carries the genetic information from DNA to the ribosome, transfer RNA (tRNA) brings amino acids to the ribosome based on the mRNA sequence, and ribosomal RNA (rRNA) is a structural component of the ribosome where proteins are synthesized.
One binding site on a ribosome holds an mRNA molecule and the other two binding?
sites hold tRNA molecules. The mRNA binding site is where the mRNA molecule binds and is read during translation. The tRNA binding sites are where tRNAs carrying amino acids bind and deliver them to the growing polypeptide chain.
Which two structures contain codons and anticodons?
Codons are found in mRNA molecules, which are involved in protein synthesis during translation. Anticodons, on the other hand, are found in tRNA molecules, which are responsible for carrying amino acids to the ribosome based on the mRNA codons.
Two types of RNA molecules are?
messenger RNA (mRNA) and transfer RNA (tRNA) are two types of RNA molecules. mRNA carries the genetic information from DNA to the ribosomes for protein synthesis, while tRNA brings amino acids to the ribosomes to be added to the growing protein chain during translation.
Where does the process of translation do in mRNA?
The newly spliced mRNA binds to a ribosome. tRNA molecules migrate towards the ribosome, these tRNA molecules carries a specific amino acid. The ribosome allows two tRNA molecules into the ribosome at a time. The tRNA molecules have complementary anti-codons to the codons present on the mRNA strand. Two tRNA move into the ribosome and their anti-codons join to complementary codons on the mRNA strand. As one molecule leaves the ribosome, its amino acid forms a peptide bond with an amino acid on the adjacent tRNA molecule, with the help of ATP and an enzyme. As the ribosome moves along the the mRNA strand, a polypeptide chain is created. The ribosome stops reading the mRNA strand when it reaches a stop codon.
What is the function of ribosomal (rRNA)?
rRNA is a massive molecule consisting of two parts; a small section, and a large section. It is between these two sections that the mRNA fits, and into the large selection that the tRNA complexes (with attached amino acids) are taken. rRNA molecules have two main binding sites. When a tRNA molecule is bound, the mRNA molecule moves along one space, and another tRNA molecule binds. When this happens, the amino acids at the ends of the tRNA molecules are very close together, and a peptide bond forms. The mRNA then moves along again and the first tRNA molecule breaks away.

What two types of molecules are involved when the codon pairs with its anticodon?
The two types of molecules involved when the codon pairs with its anticodon are messenger RNA (mRNA) and transfer RNA (tRNA). The mRNA carries the codon sequence, while the tRNA carries the anticodon sequence that base-pairs with the codon during translation.
The actual function of RNA in protein synthesis is not yet fully understood?
Yes, it is. There are two types of RNA, mRNA (messenger RNA) which copies the DNA codons in reverse, and tRNA (transfer RNA), which recopies from the mRNA the codon in reverse, thus restoring the correct codon from the DNA. The tRNA then finds its corresponding amino acid in the ribosome and brings it to the growing polypeptide chain, attaching it in the proper place, until an entire protein is made.
Which type of RNA has amino acids covalently attached?
Transfer RNA (tRNA) has amino acids covalently attached to it during protein synthesis in the cell. Each tRNA molecule carries a specific amino acid to the ribosome based on the codon it recognizes on the mRNA strand.
What does tRNA bring amino acid to the nucleus or ribosomes?
tRNA brings the complementary base pair to the mRNA already in place. The complementary base pair codes for a certain amino acid. So tRNA does bring the amino acids to the ribosome by bringing the correct code in the sequence to make a protein.
What identifies the specific amino acid for tRNA?
The anticodon on the tRNA molecule is what determines the specific amino acid it carries. The anticodon base pairs with the complementary codon on the mRNA during translation, ensuring that the correct amino acid is added to the growing polypeptide chain.
