What would happen to translation if a ribosome skipped one or more codons?
If a ribosome skips one or more codons during translation, it can result in a frameshift mutation. This mutation can alter the reading frame of the mRNA sequence, leading to the synthesis of a completely different protein with potentially nonfunctional or altered properties. The severity of the impact depends on where in the mRNA sequence the ribosome skips codons.
What would happen if during translation of a protein the mRNA codon UAA sequence was presented?
If the mRNA codon UAA is encountered during translation, it serves as a stop codon, signaling the ribosome to stop protein synthesis and release the completed protein. This results in the premature termination of translation, leading to a shorter and incomplete protein being produced.
What would happen if a single nucleotide mistake were made in the replication process?
it cased that a another nucleotide replaces primary nucleotide and happens mutation.
What would happen if a eukaryotic ribosome had only one tRNA binding site instead of the P and A sites we see in today eukaryotic ribosomes and still needed to execute translation?
If a eukaryotic ribosome had only one tRNA binding site, it would be unable to function in protein synthesis. The P site is where the tRNA carrying the growing polypeptide chain binds, while the A site is where the incoming aminoacyl-tRNA binds. Without these distinct sites, the ribosome would not be able to coordinate the movement of tRNAs during translation.
What will happen after the ribosome joins the methionine and phenylalanine?
The ribosome breaks he bond between methionine and it's tRNA. The tRNA floats away from the ribosome, allowing the ribosome to bend to another tRNA. The ribosome moves along the mRNA, binding new tRNA molecules and amino acids.
What steps happen first in translation?
The mRNA molecule attaches to a ribosome where it will be translated.

The severity of the impact depends on where in the mRNA sequence the ribosome skips codons.
What would happen if a piece of mRNA didn't have AUG at the beginning?
If the mRNA doesn't have AUG at the beginning, it may not be recognized by the ribosome as the start codon for translation. This can result in the ribosome not initiating translation properly, leading to errors in protein synthesis or premature termination of translation.

If the mRNA codon UAA is encountered during translation, it serves as a stop codon, signaling the ribosome to stop protein synthesis and release the completed protein. This results in the premature termination of translation, leading to a shorter and incomplete protein being produced.
What the steps of translation?
Translation involves taking the message that's in the messenger RNA and in a sense decoding the message from the language of nucleic acids to the language of proteins or polypeptides. For translation to happen, the messenger RNA goes to the cytoplasm where it is attached to a cellular structure called a ribosome. Ribosome's are two part molecular assemblies consisting of various proteins plus a special kind of RNA called ribosomal RNA. Ribosomal RNA is involved in catalyzing some of the chemical reactions of translation.

What will happen if the ribosome reads uaa uag or uga?
If you are asking this question to cheat at school shame on you. But I don't care I don't know you, I'm not your parent or teacher. It will read "STOP". actually, this answer is correct. When the ribosome reads uaa, uag, or uga, these sequences are known as stop codons. It will read stop. Also, no tRNA can bind to a stop codon... there are no tRNAs with anticodons complementary to the termination codons, so no tRNA enters the A site of the ribosome. Release factors are induced. RF1 to either UAA or UAG, RF2 to either UGA or UAA. RF3 forms a complex with GTP (energy source) and binds to the ribosome. These release factors promote cleave of the tRNA in the P site. GTP is hydrolyzed (reduced) to GDP. The tRNA is released from the P site, mRNA is released from the ribosome, and the ribosome leaves. -zdrum
Where in the cell does transcription and translation happen?
In prokaryotes (cells without nuclei), both transcription makes RNA from DNA and translation makes proteins from mRNA in the cytoplasm. In eukaryotes (cells with nuclei), transcription occurs in the nucleus, while translation occurs in the ribosomes of the cytoplasm.
What will happen after the ribosome joins the methionine and phenylalanine?
The ribosome breaks he bond between methionine and it's tRNA. The tRNA floats away from the ribosome, allowing the ribosome to bend to another tRNA. The ribosome moves along the mRNA, binding new tRNA molecules and amino acids.
How is protein synthesis different in prokaryotes and eukaryote?
In prokaryotes, transcription and translation happen at the same time. -APEX Learning®️ 2021
