There are a variety of enzymes used in replication. Helicase is used to open the hydrogen bonds that connect the two strands. However, this causes a tension to form in the strands (like a wind up toy) so some of it needs to be released. This is done by topoisomerase, which cuts the strands, lets them spin out some of the tension and attaches the DNA back together again. Moving behind helicase, is an enzyme called SSBP. This basically binds to the DNA sequence to prevent it from reattaching to itself after helicase unzips it; DNA would otherwise just bond back with the other strand. Then an RNA Polymerase called primase comes and attaches a primer to the DNA strands. This is needed because the next enzyme, DNA polymerase will not from scratch and needs a base to work from: the primer serves this role. Starting on the primer, DNA Polymerase III synthesizes the new strand, but the primers are still left on the strands. These will be removed by DNA Polymerase I which also adds new nucleotides to the hole left by the primer. Finally, an enzyme called ligase fills the one nucleotide gap left between the primer and the newly synthesized DNA with a sugar phosphate backbone (not another nucleotide)

∙ 13y agoDNA Helicase - The enzyme responsible for separating the two strands of DNA, normally in the conformation of a helix, so that they can be copied during DNA replication.
DNA Ligase - The enzyme responsible for sealing together breaks or nicks in a DNA strand, and responsible for patching together Okazaki fragments on the lagging strand during DNA replication.
DNA Polymerase - The enzyme responsible for catalyzing the addition of nucleotide subunits to DNA both during and after DNA replication.
Primase - The enzyme responsible for initiating synthesis of RNA primers on the lagging strand during DNA replication.

DNA polymerase- adds the complementary base pairs
DNA replication is a semi-conservative process. This means that after a strand of DNA is replicated, half is old and half is new.

They bond nucleotides (C,G,A,andT) together to make a new strand in order.
Another enzyme is DNA Ligase-
They seal the gaps in a new DNA strand.

What two nucleic acids are involved in transcription?
The nucleotides that are involved in transcription are known as uracil (U). This is what will be used in the RNA transcription to the ribosomes.
What is C H O in nucleic acids?
CHO is not in nucleic acids...
Are ribozomes carbs proteins lipids or nucleic acids?
nucleic acids. they are rna enzymes, and rna is a nucleic acid
What is the monomer of Nucleic Acids?
monomer of nucleic acids are a sugar, phosphate group, and a nitrogenous base
What statement best describes nucleic acids?
Nucleic acids are polymers. They are made of monomers Nucleotides.
How is information converted in translation?
From nucleic acids to amino acids
What are the nucleic acids?
Nucleic acids (DNA and RNA) are polymers of nucleotides; they are involved in genetics.
What nucleic acids are involved in transcription?
Deoxyribose nucleic acid, transcribed into, Ribose nucleic acid.
What does the code for genetic information change to during translation?
Nucleic Acids to Amino Acids--APEX
What are DNA and RNA examples of?
Nucleic acids
Are fatty acids involved in translation?
no
What two nucleic acids are involved in transcription?

How does the process of translation convert information?
From a nucleic acid code to an amino acid code
What macromolecules that function as the genetic material and are involved in protein systhesis are?
nucleic acids
What macromolecule provides instructions for growth?
Nucleic acids
How do transciption and translation change information from one form to another?
From nucleic acids to amino acids. Transcription copies the nucleotide sequence of DNA into RNA; in translation ribosomes recreate the messenger-RNA pattern into a copy of the sequence.
What is the name of the macromolecules that makes up DNA?
Nucleic acids.
