What is the subunit of a ribosome holds onto the mRNA strand?
The ribosomal subunit of a ribosome holds onto the mRNA strand
The code of mrna directly dependent on the?
The sequence of mRNA is directly dependent on the sequence of DNA in the process of transcription. During transcription, RNA polymerase reads the DNA sequence and synthesizes a complementary mRNA strand. Changes in the DNA sequence can result in changes in the mRNA sequence, affecting the protein product that is ultimately produced.
How are the codes for proteins carried fromthe nucleus to the ribosomes?
The codes for proteins are carried from the nucleus to the ribosomes by messenger RNA (mRNA). After transcription in the nucleus, the mRNA strand carries the genetic information encoded in the DNA to the ribosomes in the cytoplasm for translation into proteins. This process is crucial for protein synthesis within the cell.
How many tRNA nucleotides form an anitcodon that will attach to the mRNA codon?
The codon and the anticodon interact with each other via hydrogen bonding, hence both the codon and anticodon are made up of the same number of nucleotides, which is three.
What is the difference between translation and transcription?
Transcription, which comes first, is when DNA information is read and matched onto an RNA strand. The new strand of RNA now has codons that match up with those in the DNA. After this, the RNA travels into the nucleus of the cell, where its information is used to create long protein chains in the process of translation.
Mrna is synthesized in translation or transcription?
mRNA is synthesized during the process of transcription, which occurs in the nucleus of the cell. During transcription, the information stored in DNA is copied onto mRNA, which can then move out of the nucleus and into the cytoplasm for translation. Translation is the process by which the mRNA is read by ribosomes to produce a specific protein.
What two steps must occur in protein synthesis?
The two main steps in protein syntheis are transcriptionand translation. In transcription, the enzyme RNA Polymerase uses a DNA strand as a template to make a transcript of messenger RNA. This transcript is then translated into protein by the ribosome.
How the tRNA docks on the mRNAexplain in terms of nitrogen bases?
The tRNA docks onto the mRNA through complementary base pairing between the anticodon on the tRNA molecule and the codon on the mRNA strand. This base pairing ensures that the correct amino acid is brought to the ribosome during protein synthesis. The interaction between the nitrogen bases is specific, with adenine (A) pairing with uracil (U) and cytosine (C) pairing with guanine (G).
Why is DNA replication caled semiconverative?
Because when the two strands of the double helix are unwound for replication each strand acts as a template to replicate a new strand onto. So, you get four strands, two pair. One of that pair is a new strand and one of the pair is the old strand that was the template strand.
Where is DNA decoded onto in protein synthesis?
DNA is first transcribed into mRNA in the nucleus of the cell. This mRNA then moves to the cytoplasm, where it is translated by ribosomes. The ribosomes decode the mRNA sequence and synthesize the corresponding amino acids into a protein. Therefore, protein synthesis occurs in the cytoplasm.
What happens during the transcription of a given portion of a DNA molecule?
During transcription, an enzyme called RNA polymerase binds to the promoter region of the DNA molecule. The polymerase then unwinds the DNA double helix and synthesizes a complementary RNA strand using one of the DNA strands as a template. This process results in the formation of a single-stranded RNA molecule that carries the genetic information encoded within the DNA onto mRNA.
What carries information for the DNA int he nucleus out onto the cytoplasm of the cell?
The RNA, or mRNA. It carries the info to the cytoplasm and the ribosomes.
