  • Do neuromodulators travel a longer or shorter distance than neurotransmitters, or is it the same?

    Best answer: Neuromodulators travel longer than neurotransmitters. This is due to the location they are synthesized. Nueromodulators are made in the cell soma/body and have to travel to the presynaptic terminal. Neurotransmitters are already located at the presynaptic terminal.

  • What problem(s) would arise for genetic engineers if DNA ligase did not exist?

    Best answer: You are correct A is for sure. Dideoxy sequencing is used to break down DNA so you can be able to determine the genome. So I don't think that is the answer. PCR is used to determine pieces of DNA. Both these methods are breaking down the DNA. Ligase is needed to put together the lagging strands together.

  • Protein Synthesis biology homework help? I don't understand transcription?

    Best answer: Ok I am going to give you the overall picture first. DNA makes RNA by a process called transcription RNA makes protein by a process called translation. In transcription you have a DNA sequence like above 3'TGTGCTCGA 5'. This sequence is going to be used as the template strand to make RNA by RNA polymerase. Therefore your... show more
    Best answer: Ok I am going to give you the overall picture first. DNA makes RNA by a process called transcription RNA makes protein by a process called translation. In transcription you have a DNA sequence like above 3'TGTGCTCGA 5'. This sequence is going to be used as the template strand to make RNA by RNA polymerase. Therefore your result will be 5'ACACGAGCU 3' this sequence you have transcribed is now called mRNA. Keep in. Mind when you deal with mRNA T nucleotide will now become U. Here every 3 nucleotide will code for an amino acid. So ACA, CGA, GCT will code for 3 different amino acids. Use and amino acid chart to figure out what these will code for. Each 3 nucleotide equal a codon. You have to use these codon to make protein with the help of tRNA. tRNA will have the anticodon to the codon. Lets say for example if you have a codon ACA then it's anti codon is UGU. In DNA replication or transcription you will always add nucleotide to a growing chain on the 3' OH end. Hope this helps! If you get a chance try some YouTube videos.

    Best answer: If there is a covalent bond then it would be harder to separate both strands for replication since all DNA Replication proteins do is disrupt hydrogen bonds.

    Best answer: If there is a covalent bond then it would be harder to separate both strands for replication since all DNA Replication proteins do is disrupt hydrogen bonds. These interactions are weaker than covalent bonds. If a mutation occurs in the promoter than that gene will not be able to be transcribed. Transcription factors and RNA polymerase will not be able to carry out transcription. Just right the complementary to it but instead of A binding to T it will bind to U. So A H-bonds with T and C with G.

  • Prokaryotic genes are POLYCISTRONIC, so, do they have terminator codons that punctuate each CISTRON?

    Best answer: Yes they are polycistronic genes. Like eukaryotes they have a stop codon. They have a release factor which has tRNA shape which force peptidyl transferase to add water instead of amino acid making translation complex unbind ending translation.
