Final answer:
Eukaryotic sliding clamps are composed of three polypeptides. They enhance the attachment of DNA polymerases to DNA, increasing the efficiency of DNA replication. Option C is correct.
Step-by-step explanation:
The sliding clamps of eukaryotes are made up of three polypeptides. The sliding clamp is a protein complex that is important in DNA replication because it increases the processivity of DNA polymerases, meaning it helps the polymerase stay attached to the DNA strand longer, thereby speeding up the replication process.
To provide a bit of additional context, consider some related information in molecular biology:
It takes three "letters" or nucleotides of an RNA molecule in sequence to provide the code for a single amino acid. This sequence of three nucleotides is called a codon.
In eukaryotes, DNA is wrapped around proteins called histones, not sliding clamps or single-stranded binding proteins.
If you translate the mRNA sequence 5'-AUGGGCUACCGA-3', the peptide would be three amino acids long since the sequence contains three codons before it reaches a stop codon or continues beyond the provided sequence.
Additionally, meiosis normally results in the production of four haploid cells. Nitrogen, with an atomic number of seven, has two electron shells. The linkage that combines two amino acids occurs at the peptide bond.
