Which of the following processes of genetic information flow can occur under lab conditions, but has never been observed to occur under natural conditions (either in living cells or in viruses)? transcription of RNA from a DNA template (using DNA-dependent-RNA-polymerase) self-replication of RNA from an RNA template (using RNA-dependent-RNA-polymerase) direct-translation of protein from a DNA template (using special ribosomes) self-replication of DNA from a DNA template (using DNA-dependent-DNA-polymerase) translation of protein from an RNA template (using ordinary ribosomes)
Suppose you have been directed to find new enzymes to use in the breakdown of wood in order to process biofuel (switchgrass, for example). Suppose you wanted to use fungal or bacterial DNA from the environment in order to do so. DNA can be unwound from the double stranded double helix into single strands, amplified, separated on gels by size, stained with dyes. It can be mutated by a variety of means. It can be sequenced. Describe one or more of the ways that you might manipulate DNA towards the stated goal. Relate the technology you plan to utilize to the structure of DNA. (You can break this into multiple posts, as multiple procedures might be used).
Which of the following features is common to both DNA replication and RNA transcription? Both RNA and DNA polymerase form a sugar-phosphate bond between the 3' hydroxyl and the 5' phosphate. Both RNA and DNA polymerase require oligonucleotide priming. Both RNA and DNA polymerase incorporate deoxyribonucleotides into the growing sequence. Both RNA and DNA polymerase initiate at promoter sequences. Both RNA and DNA polymerase have extensive proofreading editing.
List and describe three important processes are affected by DNA supercoiling.
DNA from actively dividing bacteria was isolated and examined to find two groups of DNA. One group DNA included very large molecules (thousands or even millions of nucleotides long), and the other included short stretches of DNA (several hundred to a few thousand nucleotides in length). What was the researcher actually seeing in these two groups? Group of answer choices mRNA molecules and siRNA molecules Okazaki fragments and RNA primers leading strands and Okazaki fragments leading strands and RNA primers
In next-generation sequencing, which of these advances allows for massively parallel sequencing? a. Pieces of DNA are fixed to a surface, so we can tell which new nucleotides were added to each piece. b. DNA sequences are read in real-time as nucleotides are added to each piece. c. Each segment of the genome can be pieced back together through shotgun alignment d. Single molecules of DNA can be read without the need for amplification.
At the molecular level, speculate on some ways that the environment might have an influence on DNA and its packaging
In relation to central dogma of molecular biology answer the following questions: The following segment of DNA is part of the transcription unit of a gene. You know already that RNA polymerase moves in a specific direction along this piece of DNA to convert one of the DNA strands into a single strand RNA transcript so that this entire region of DNA is made into RNA. 5′-GGCATGGCAATATTGTAGTA-3′ 3′-CCGTACCGTTATAACATCAT-5′ Given this information, a student claims that the RNA produced from this DNA is: 3′-GGCATGGCAATATTGTAGTA-5′ Give two reasons why this answer is incorrect.
Complete the table below 6. Below are several DNA sequences that are mutated compared with the wild-type sequence: 3’-T A C T G A C T GA C G A T C-5’. Envision that each is a section of a DNA molecule that has separated in preparation for transcription, so you are only seeing the template strand. Construct the complementary DNA sequences (indicating 5’ and 3’ ends) for each mutated DNA sequence, then transcribe (indicating 5’ and 3’ ends) the template strands, and translate the mRNA molecules using the genetic code, recording the resulting amino acid sequence (indicating the N and C termini). What type of mutation is each?6.a.

A researcher sequences the genome of a variety of bacterial and eukaryotic cells. She finds that the bacterial genome is smaller, but that there are more genes for a given number of base pairs in the eukaryotic cells. In other words, there are fewer genes per unit of length of DNA in the eukaryotic cells. What do you predict she will find if she examines the DNA more closely? A. All of the bacterial DNA consists of coding sequences, but this is not true of the eukaryotic DNA. B. There are more repetitive sequences in the eukaryotic DNA than in the bacterial DNA. C. There are densely packed genes in the eukaryotic DNA that were not immediately distinguishable during the first analysis. D. The bacteria have larger quantities of noncoding DNA than the eukaryotic cells.
