What is the significance of the mRNA start codon in initiating protein synthesis?
The mRNA start codon, usually AUG, plays a crucial role in initiating protein synthesis. It signals the ribosome to start translating the mRNA sequence into a protein. This codon marks the beginning of the protein coding sequence and helps establish the correct reading frame for translation.
Why methionine is removed from protein in post translation modification?
Methionine is the amino acid associated with the AUG sequence on mRNA. The AUG sequence also indicates the beginning of a gene. Though the AUG sequence is necessary for gene expression, methionine is not necessary for all proteins. This is why it is usually removed after translation.
Why does an insert mutation usually cause more defects during protein synthesis than a point mutation?
Insertion mutations can affect many amino acids in the protein.An insertion mutation usually causes more defects during protein synthesis than point mutation because an insertion mutation will affect many amino acids in the protein.
Synthesis of a protein stops when?
Synthesis of a protein stops when a stop codon is reached on the mRNA during translation. This signals the ribosome to release the newly synthesized protein so it can fold into its functional structure.

Insertion mutations can affect many amino acids in the protein.An insertion mutation usually causes more defects during protein synthesis than point mutation because an insertion mutation will affect many amino acids in the protein.
Why does a detetion mutation usually cause more defect during protein synthesis than point mutation?
Mutation usually causes the entire base sequence to defect. This usually happens during the protein synthesis.

What is the name of the process of building up large proteins in a cell?
Protein synthesis requires two steps: transcription and translationMessenger RNA (mRNA) a copy of a portion of the DNA. It carries genetic information from the gene (DNA) out of the nucleus, into the cytoplasm of the cell where it is translated to produce protein. Proteins are created by ribosomes translating mRNA into polypeptide chains. These polypeptide chains undergo PTM (Posttranslational modification) to give the mature protein.
Synthesis of a protein stops when?
Synthesis of a protein stops when a stop codon is reached on the mRNA during translation. This signals the ribosome to release the newly synthesized protein so it can fold into its functional structure.

What are inducible and non inducible enzymes?
Inducible: usually off for protein synthesis but can be turned on Non inducible, or REPRESSIBLE : usually on for protein synthesis but can be turned off Inducible: usually off for protein synthesis but can be turned on Non inducible, or REPRESSIBLE : usually on for protein synthesis but can be turned off
Why does a deletion mutation usually cause more effects during protein synthesis than a mutation?
A deletion mutation typically removes one or more nucleotides from the DNA sequence, which can disrupt the reading frame of the codons during protein synthesis, leading to a frameshift mutation. This alteration often results in a completely different and nonfunctional protein, as the downstream amino acid sequence is altered. In contrast, a point mutation (such as a substitution) may only change a single amino acid or have no effect at all if it occurs in a non-coding region or results in a synonymous codon. Thus, deletions generally have more severe consequences for protein function than point mutations.
