What is the protein strand created from the mrna strand cagaaguuccucucgc?
The mRNA sequence cagaaguuccucucgc would be translated into the protein sequence Glutamine-Lysine-Serine-Leucine-Arginine. Each set of three nucleotides (codon) in the mRNA corresponds to a specific amino acid in the protein sequence during translation.
Why do all polypeptide chains start with methionine?
In eukaryotic cells, the start codon for protein synthesis is always AUG, which codes for methionine. Methionine is the initiator amino acid that signals the ribosome to start translation. Additionally, methionine helps stabilize the structure of the nascent polypeptide chain during synthesis.
Why do cells have to produce RNA from DNA?
Cells must produce RNA from DNA in order to carry out essential cellular functions such as protein synthesis. RNA serves as a messenger molecule that carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm where proteins are made. This process is crucial for the proper functioning and regulation of cellular processes.
MRNA must pass through which membrane?
The nuclear membrane.In eukaryotic cells, DNA is transcribed into mRNA within the nucleus. Once transcription is complete the mRNA must exit the nucleus to be translated into protein, which ocurrs in the cytoplasm. Thus, mRNA must pass through the nuclear membrane.
Where must An MRNA Attach Before Protein Can Begin?
The ribosome.
