What is the function of the B subunit of DNA polymerase III in DNA replication?
Holoenzyme DNA Polymerase III
| Protein | Subunit | Function |
|---|---|---|
| B | Subunit of Topo IV | |
| Topoisomerase I | Relaxes supercoils, affecting global regulation of replication | |
| SSB | Protects single-stranded DNA from nucleolytic degradation | |
| DNA polymerase III | α | DNA synthesis |
What is a codon Anticodon?
anticodon – a sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule. The anticodon sequence determines the amino acid that the tRNA carries. codon– a sequence of three nucleotides on a mRNA molecule that encode a specific amino acid.
What is needed for translation?
The key components required for translation are mRNA, ribosomes, and transfer RNA (tRNA). During translation, mRNA nucleotide bases are read as codons of three bases.
How do you translate DNA?
Basically, a gene is used to build a protein in a two-step process:
- Step 1: transcription! Here, the DNA sequence of a gene is “rewritten” in the form of RNA.
- Step 2: translation! In this stage, the mRNA is “decoded” to build a protein (or a chunk/subunit of a protein) that contains a specific series of amino acids.
What amino acid does CCA code for?
Codon-Amino Acid Abbreviations
| Codon | Full Name | Abbreviation (1 Letter) |
|---|---|---|
| CCC | Proline | P |
| CCA | Proline | P |
| CCG | Proline | P |
| CAT | Histidine | H |
Is glycine an acid?
It is an alpha-amino acid, a serine family amino acid and a proteinogenic amino acid. It is a conjugate base of a glycinium. It is a conjugate acid of a glycinate. It is a tautomer of a glycine zwitterion.
What is the start codon in DNA?
AUG
