Look back at Figure 3. In our model, the free mRNA strand has just come from the nucleus and enters the ribosome; the machinery for making proteins. Because RNA is just a sequence of nucleotides, the ribosome d
What are: a gene, a codon, an anticodon, the generic code? What is the complementary mRNA base sequence to the DNA stand TGCCAT? a. TGCCAT b. UGCCAU c. ACGGTA d. ACGGUA e. ACCGTA Given the following sequence of DNA nucleotides- Templates DNA - TAC. What will the codon be?
There should be enough nucleotides, polymerase and other reagents left for the amplification of the less abundant genes. In a primer limited multiplex reaction, the Ct values for both genes will still be measured accurately. In a typical singleplex TaqMan reaction the primer concentrations are 900...
What are the first six nucleotides of mRNA if the sequence below represents the first cDNA strand? 5' TACGGCTATCCCTACGCCT 3' (a) 5'UGGCGA3' (b) 5'UACGGC3' (c) 5'AUGCCG3' (d) 5'AGGCGU3' What would be the anticodon of the tRNA that recognizes this codon 5'-UUA-3'. What...
When our nucleotides are bound together from the 3’ carbon on one nucleotide’s sugar to the phosphate group on the 5’ end of a different nucleotide, we start forming a strand that is referred to as the sugar-phosphate backbone (of DNA and RNA). When our nucleotides are connected in ...
(Figure 5). The proteins that bind to promoters to regulate transcription are called transcription factors. The RNA coding region, the main component of the transcription unit, contains the actual exons and introns. Theterminator, a sequence of nucleotides at the end of the transcription unit, ...
Poly-A is a repetitive sequence of adenine nucleotides added posttranscriptional to the 3’-end of a eukaryotic mRNA molecule.
Let’s start by defining two key terms: coding strand and non-coding strand. As its name suggests, double-stranded DNA is built of two complementary strands of nucleotides. In simple terms, the DNA strand that serves as a template for transcription is called the coding strand, and the compl...
DNA has a structure called a double helix. Nucleotides are attached together to form two long strands that spiral to create this structure. If you think of the double-helix as a ladder, the phosphate and sugar molecules would be the sides, while the base pairs would be the rungs. The ba...
Nucleotides contain what kind of sugars? What cell structure contains DNA? What molecules make up the backbone of the RNA molecule? What holds the two strands of DNA together? What are the macromolecules DNA and RNA referred to as? What sugar is found in DNA and RNA?
