What is the difference between a coden and an anti coden?
a codon is the sequence of three nucleotides of mRNA, the anti codon is the amino acid of tRNA that is matched to the codon.
What event occurs during the elongation stage?
mRNA passes through ribosomal subunits, tRNA deliver amino acids to the ribosomal binding site in the order specified by the mRNA, & peptide binds forms between the amino acids and the polypeptide chain grows
What role does rna play in gene expression?
RNA plays a key role in gene expression by serving as the intermediary between DNA and proteins. RNA molecules are transcribed from DNA and then used as templates for protein synthesis during translation. Different types of RNA, such as messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), each contribute to various steps in the gene expression process.
What role does the structure of RNA and DNA play in protein synthesis?
mRNA. tRNA,
What role does Trina RNA play in gene expression?
Trna RNA, or transfer RNA, plays a crucial role in protein synthesis by bringing amino acids to the ribosome during translation. It ensures that the correct amino acid is added to the growing protein chain based on the codons in the mRNA.
How many different RNA are found in cells?
There are three main types of RNA found in cells: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNA molecules play crucial roles in protein synthesis and gene expression within cells.
What molecules must pass between nucleus and cytoplasm?
Molecules that must pass between the nucleus and cytoplasm include mRNA (messenger RNA), tRNA (transfer RNA), and proteins. These molecules play crucial roles in gene expression and protein synthesis within the cell.
What consisting of only about 80 nucleotides which assume a looped shape?
MicroRNA is a type of small non-coding RNA consisting of about 80 nucleotides that forms a looped secondary structure. It plays a crucial role in post-transcriptional regulation of gene expression by binding to target messenger RNA molecules.
Which mutation cannot occur in a tRNA encoding gene?
A mutation that changes the start codon of a tRNA gene is unlikely to occur, as that could prevent proper translation of the tRNA. Mutations that disrupt critical structural elements such as the anticodon loop or the acceptor stem are also less likely, as they would affect the tRNA's functionality.
Does tRNA have proteins?
Yes, tRNA molecules do not have proteins. They are small RNA molecules that play a key role in protein synthesis by carrying specific amino acids to the ribosome during translation.
What is relatively small consisting of only about 80 nucleotides wich assume a looped shape?
This description matches a microRNA (miRNA). MiRNAs are small non-coding RNA molecules that are about 18-25 nucleotides in length and often assume a looped structure. They play important roles in post-transcriptional regulation of gene expression.
What are the functions of each type of the RNA?
mRNA carries genetic information from DNA to the ribosome for protein synthesis. tRNA brings amino acids to the ribosome during protein synthesis. rRNA makes up the ribosome and is involved in protein synthesis. PTEN RNA regulates gene expression and cell growth. miRNA regulates gene expression by binding to target mRNAs. snoRNA guides chemical modifications of other RNAs.
What is the order or events in gene expressions?
Gene expression involves transcription of DNA into mRNA, followed by translation of mRNA into proteins. After transcription, the mRNA undergoes processing steps such as splicing and capping before it can be translated into a protein by ribosomes. Post-translation modifications may also occur to ensure proper functioning of the protein.
What molecule contain anticodons?
The tRNA gene sequence is the anti-codon while mRNA is the codon sequence.
