    induction of the lacZ gene since IS cannot be removed by the inducer from the operator. 3. Define the following terms: a. enhancer- sequence that stimulates maximal transcription of distant genes; affects only genes on the same DNA molecule (is cis acting)‚ contains short consensus sequences‚ is not fixed in relation to the transcription start site‚ can stimulate almost any promoter in its vicinity‚ and may be upstream or downstream of the gene. The function of an enhancer is independent of sequence

    translating the codons into proteins and stop codons tell the tRNA to stop translating codons into proteins. They are essential in the process of producing proteins. 6. Describe the processes of transcription and translation in your own words‚ based on what you have observed in the Gizmo. Transcription: Protein synthesis process starts in the nucleus where DNA is found‚ which is a double chain of sugars and phosphates that are joined by pairs of nucleic acids. These are adenine‚ guanine‚ cytosine

    Transcription‚ or RNA synthesis‚ is the process of creating an equivalent RNA copy of a sequence of DNA. Both RNA and DNA are nucleic acids‚ which use base pairs of nucleotides as a complementary language that can be converted back and forth from DNA to RNA in the presence of the correct enzymes. During transcription‚ a DNA sequence is read by RNA polymerase‚ which produces a complementary‚ antiparallel RNA strand. As opposed to DNA replication‚ transcription results in an RNA complement

    states‚ “In the process of transcription‚ DNA is used as a template to produce a molecule of mRNA. This occurs in the nucleus.” RNA synthesis transcription is the first step of gene expression‚ in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. During transcription‚ a DNA sequence is read by an RNA polymerase‚ which produces a complementary‚ antiparallel RNA strand‚ also unlike DNA replication where DNA is synthesised‚ transcription does not involve an RNA primer

    RNA are different in ways. One way is that DNA is double stranded and RNA is single stranded. Another way is that DNA contains thymine and RNA contains nitrogenous base uracil. Transcription is used to produce complementary mRNA molecule. Transcription uses the enzyme called RNA polymerase. The transcription process occurs inside the nucleus in a eukaryotic cell. First the RNA polymerase joins with a DNA molecule and separates its two strands. One strand of the DNA molecule assembles nucleotides

    Gene expression begins with RNA synthesis. The transcription enzyme RNA polymerase joins RNA nucleotides according to the base sequence in DNA. Prokaryotes have one type of RNA polymerase. Transcription has four major processes Template recognition‚ Initiation‚ Elongation‚ and Termination. First RNA polymerase binds to duplex DNA. Then‚ DNA is unwound at promoter and then chain

    (Wolfe‚ 2000a) Role of mRNA • Transcription begins within the nucleus of a cell when mRNA binds to a segment of DNA and produces a copy. • This mRNA moves out of the nucleus and into the cytoplasm. • Once in the cytoplasm‚ the mRNA is able to become a part of the process of translation. • Codons in single strands of mRNA join with anticodons of tRNA (transfer RNA) to form proteins.
