Complete the following Venn diagram, which compares and contrasts DNA and RNA. When a virus of this type takes over a host cell, it makes DNA from its RNA. GGAGCTCCAGAGACCTTGAGACCAGTTCA Select one: a. GGAGCTCCAGAGACCTTGAGACCAGTTCA b. CCUCGAGGUCUCUGGAACUCUGGUCAAGU c. GGAGCUCCAGAGACCUUGAGACCAGUUCA d. The intermediary RNA breaks that cycle of dependence because it can both encode genetic information and act catalytically like enzymes. DNA polymerase c. RNA polymerase d. ribozyme e. ribosome The correct answer is: ribosome Which one of these RNA sequences could have been made from the following DNA template? insertion of an incorrect nucleotide by RNA polymerase during transcription a mutation in the coding sequence within the DNA a mutation in the promoter sequence within the DNA a mistake during splicing that leads to … 5. For example, a trinucleotide repeat is made up of 3-base-pair sequences, and a tetranucleotide repeat is made up of 4-base-pair sequences. Following the definition of RNA editing given above as nucleotide alterations which could just as well have been encoded in the genomic sequence, the sequence alterations in tRNAs of Acanthamoeba classify as bona fide editing [28, 29]. Certain viruses, like HIV, actually contain RNA.
A repeat expansion is a mutation that increases the number of times that the short DNA sequence is repeated. 6. Ribonucleic acids, also called RNA, perform multiple important roles in living cells. RNA containing molecules also contribute to the regulation of gene expression and function as enzymes. Nucleotide repeats are short DNA sequences that are repeated a number of times in a row. Which of the following could NOT introduce a premature stop codon in mRNA? The viral DNA is then used to make an RNA copy, which is used to make viral proteins. These nucleotides have three parts: 1) a five carbon ribose sugar, 2) a
During sequence analysis of the mitochondrial genome in this amoeba 13 of the 16 tRNAs encoded in the mitochondrial DNA were predicted to contain mismatches … You could be forgiven for thinking that it pretty much solves the conundrum of how the replication of DNA could have avoided a chicken-and-egg impasse: DNA replication requires protein enzymes, but proteins must be encoded in DNA.
To ensure the success of 5′ end-labeling, the RNA substrate should be prepared to its highest purity, which can usually be achieved by gel purification (8 M urea-PAGE gel electrophoresis). In all cells, the flow of genetic information is from DNA ( RNA ( proteins.
Like DNA, RNA polymers are make up of chains of nucleotides.
The RNA substrate could be prepared either from in vitro transcription or in vivo purification. RNA is needed for protein synthesis and DNA replication. This nucleotide contains the five-carbon sugar deoxyribose (at center), a nitrogenous base called adenine (upper right), and one phosphate group (left).
