What else can I help you with?
What does the first nucleotide attach to because DNA polymerase can only add nucleotides to a pre-existing strand?
A primer molecule is required for DNA polymerase to initiate the addition of nucleotides. This primer provides a starting point for DNA polymerase to begin adding nucleotides in the correct sequence. Once the primer is in place, DNA polymerase can add nucleotides complementary to the template strand.
What is the name of the enzyme that would have placed nucleotides into the replicating DNA in the correct order?
The enzyme responsible for placing nucleotides into replicating DNA in the correct order is called DNA polymerase. DNA polymerase adds complementary nucleotides to the growing DNA strand during replication, following the rules of base pairing (A with T and C with G).
What catalyzes the linking together of nucleotide subunits?
Enzymes called DNA polymerases catalyze the linking together of nucleotide subunits in DNA replication. These enzymes attach new nucleotides to the growing DNA strand based on the complementary base pairing between the original template DNA strand and the new nucleotides.
Is it possible for a nitrogenous base a ribose sugar and a phosphate to self assemble?
Yes, nitrogenous bases, ribose sugars, and phosphates can self-assemble to form nucleotides, the building blocks of nucleic acids like DNA and RNA. The nitrogenous base binds to the ribose sugar, and a phosphate group can then attach to the sugar to form a nucleotide. These nucleotides can further assemble to form DNA or RNA strands through complementary base pairing.
What are protein strands that attach to the centromere?
Spindle fibers.
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.

Describe the role of protein synthesis DNA nucleotides RNA ribosomes rough ER and golgi apparatus?
DNA contains the instructions for protein synthesis. RNA transcribes these instructions, which are then translated by ribosomes to assemble proteins. The rough ER helps in protein synthesis by providing a surface for ribosomes to attach, while the Golgi apparatus processes and packages the proteins for transport within or outside the cell.
If trna had an agc anticodon it could attach to what?
If tRNA had an AGC anticodon, it could attach to a codon on mRNA that is complementary to it, which would be UCG. This would ensure the correct amino acid is brought to the ribosome during protein synthesis.

What is a riboprotein?
riboNucleoproteins are protein+RNA. The Ribo means it is RNA and not DNA (deoxyribo) nucleotides. Nucleotides (RNA or DNA) can hold onto proteins and subsequently react with substrates or attach to other macromolecules such as proteins. Some proteins will not work without nucleotides attached. Ribosomal proteins, on the other hand, are proteins that work with ribosomes. There are about 79 proteins that interact with ribosomes.
Is it possible for a nitrogenous base a ribose sugar and a phosphate to self assemble?
Yes, nitrogenous bases, ribose sugars, and phosphates can self-assemble to form nucleotides, the building blocks of nucleic acids like DNA and RNA. The nitrogenous base binds to the ribose sugar, and a phosphate group can then attach to the sugar to form a nucleotide. These nucleotides can further assemble to form DNA or RNA strands through complementary base pairing.
What are protein strands that attach to the centromere?
Spindle fibers.
What protein with heads that attach in cross bridging?
myosin
Protein strands that attach to the centromere region during M-phase of cell cycle?
During Metaphase the protein strands that attach to the centromere region are called spindle fibres.
How is mRNA read by the cellular machinery during protein synthesis?
mRNA is read by the cellular machinery during protein synthesis through a process called translation. Ribosomes attach to the mRNA and move along it, reading the genetic code in groups of three nucleotides called codons. Each codon corresponds to a specific amino acid, which is added to the growing protein chain. This process continues until a stop codon is reached, signaling the end of protein synthesis.
