Does transcription and translation occur all the time?
Therefore, the processes of transcription, translation, and mRNA degradation can all occur simultaneously. The intracellular level of a bacterial protein can quickly be amplified by multiple transcription and translation events occurring concurrently on the same DNA template.
Where do a lot of transcription and translation occur in the cell cycle?
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.
Does DNA replication and transcription occur at the same time?
All three processes can occur simultaneously. In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation.
When and where in the cell does DNA replication occur?
DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.
Can each RNA transcript be translated many times?
However, errors occurring during transcription often elicit more dire consequences than those occurring during translation because individual mRNAs can be translated up to 40 times (primary sources), resulting in a burst of flawed proteins. …
Does translation occur in all cells?
Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.
What happens during DNA replication transcription and translation?
DNA polymerase links nucleotides together to form a new strand, using the pre-existing strand as a template. Transcription is the synthesis of mRNA copied from the DNA base sequences by RNA polymerase. Translation is the synthesis of polypeptides on ribosomes.
Does DNA replication occur before or after protein synthesis?
Protein synthesis makes proteins, while DNA replication makes DNA . DNA replication occurs in the nucleus and produces two identical sets of DNA. Protein syntheses produces mRNA, which is then translated by tRNA molecules carrying amino acids to produce a polypeptide or protein.
Where does DNA replication transcription and translation occur?
the nucleus
DNA replication occurs in the nucleus. DNA transcription occurs in the nucleus. mRNA translation occurs at ribosomes.
How often does DNA replication occur?
once per cycle
The preparation for DNA replication initiation is tightly linked to cell-cycle progression, ensuring that replication occurs only once per cycle. The time is ripe for a molecular dissection of the links between the two processes.
What is the process of translation from DNA to protein?
Translation: DNA to mRNA to Protein | Learn Science at Scitable Genes encode proteins, and the instructions for making proteins are decoded in two steps: first, a messenger RNA (mRNA) molecule is produced through the transcription of DNA, and next, the mRNA serves as a template for protein production through the process of translation.
What are the similarities between DNA replication and transcription?
DNA replication and transcription both synthesize new molecules by base-pairing In transcription, a strand of mRNA is assembled on a DNA template using RNA nucleotides • Uracil (U) nucleotides pair with A nucleotides •RNA polymeraseadds nucleotides to the transcript
What is the result of transcription and translation?
The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule. Figure 1: A gene is expressed through the processes of transcription and translation.
How is the switch from transcription to replication regulated?
The switch from transcription to replication, that is the switch from antigenome production to genomic nucleic acid for packaging, is highly regulated, and unlike RNA viruses, there is the strict demarcation with respect to timing of genomic DNA replication. Early genes, which code for catalytic (e.g., polymerase) and regulatory proteins]
