can apply this tool. The cassette is stably and efficiently transmitted and expressed in the next generation. Utilization of different promoters enables the transcription of tissue and stage specific hairpin RNA from the cassette‚ directing conditional inhibition of gene functions by RNAi. Additionally‚ the transcription of mRNA and translation of the ORF can be directed which result in the conditional activation of gene functions. The efficient integration and expression of piggyBac-derived cassettes

What would be the effect of a deleltion or an addition in one of the DNA nucleotides? What would be the effect of a substitution in one of the nucleotides? STANDARDS: In the transcription phase of protein synthesis‚ students were given a point for a correct definition of transcription. They were awarded one point for mentioning each of the following:

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA molecules are composed of two strands that form a helical ascending spiral. They fit together like the opposing teeth of a zipper and are held together by weak interactions called hydrogen bonds. These two strands is a long string of subunits called nucleotides‚ each attached to the one immediately about it and the one immediately below it to form a long chain. Each

Double Helix Two DNA strands form a helical spiral‚ winding around a helix axis in a right-handed spiral. The two polynucleotide chains run in opposite directions. The sugar-phosphate backbones of the two DNA strands wind around the helix axis like the railing of a spiral staircase. The Backbone DNA is in the form of a double helix. This means that two helices‚ or sides‚ twist around a center. The sides of the double helix are referred to as the backbone of the DNA strand. They are made up

a. Transcription is the first step of protein synthesis it uses a sequence of DNA nucleotides to produce a sequence of RNA nucleotide. b. RNA polymerase bonds to RNA nucleotides together‚ attaches to the promoter site at the start of the gene. 4. 5. a. -Messenger RNA contains information to synthesize proteins. -Transfer RNA is used to transfer amino acids during the next step. -Ribosomal RNA makes up part of a ribosome. b. Transcription takes place in the nuclease 6. Translation takes

this structure is called the coding strand. The second strand that lies below the coding strand is called the template strand. In order for a RNA polymerase to go from the upper strand to the second strand it must go through the process called transcription. First‚ the RNA polymerase must attach on to one of the genes on the coding strand on DNA. Once the RNA polymerase attaches‚ it must then begin the process called initiation. This means that the RNA polymerase opens up both strands of DNA in order

A gram-negative bacteria like Escherichia coli protect its cells from stresses that cause the misfolding of proteins‚ which are later secreted across the cytoplasmic membrane (Raivio et al.‚ 2013). In response to the secretion of misfolded proteins‚ gram-negative bacteria use two major envelope stress responses (Raivio et al.‚ 2013). One of the envelope stress responses is the Cpx envelope stress response and it is activated by a diverse set of inducing signals‚ such as alkaline pH‚ chloride ions
