What does DNA primase do? Why is DNA considered a nucleic acid ? What is the reason behind DNA being acidic? What are the functions of DNA and through what process does the DNA acquire these functions? Why is DNA replication necessary? What important features of the structure of DNA are ...
Why is there a need for the primase to make an RNA primer for DNA replication? Why are DNA strands anti-parallel? What is the main function of DNA replication? How are primers involved in the replication of DNA? Describe the process of DNA replication. ...
Glycosylated Nsp4 is necessary for normal DMV formation [34,35], as described in SARS-CoV and MHV [36]. The N-terminal region of Nsp4 comprising the first three transmembrane regions necessary for DMV membrane pairing [37]. We observe in Fig.3b that they are highly conserved among all co...
To elucidate how these processes, which are also involved in other nuclear processes, regulate replication initiation, it is necessary to identify and characterize elements in cis that serve as potential origins of replication in eukaryotes at a genome-wide level. Furthermore, it is becoming ...
Why is DNA ligase popularly called the molecular glue? Why is RNA a single strand? Why is DNA necessary for protein synthesis? Why are nucleotides added to the 3' end? Why do viruses have both RNA and DNA? What is the significance of the 5' and 3' positions in the deoxyribose sugar ...
mRNA molecules are translated into amino acid sequences by the ribosomes in a cell. This sequence of amino acids can then be folded in the specific manner necessary to create functional protein.Answer and Explanation: A codon must consist of at least 3 bases, not amino acids. A codon ...
Why is uracil excluded from DNA replication but not RNA? Why is the continuous synthesis of DNA not possible? Why does a plasmid ligated from a restriction fragment consist of an even number of fragments? Why do eukaryotic cells need to be able to turn genes on and off...
Why do eukaryotic cells need to be able to turn genes on and off as necessary? Why does primase make RNA and not DNA? Why is DNA acidic? Why don't all cells make all proteins coded for their DNA? Why is DNA polymerase used in PCR?
Discuss why DNA is often called a "protein recipe". Why do all living creatures have DNA? What is the reason behind DNA being acidic? (a) Describe the levels of DNA packaging. (b) Why is this important to the cell? Why is DNA replication necessary? Explain why DNA has an overall ...
Although many natural amino acids are known, only 22 are so-called proteinogenic, that is they are the ones involved in protein synthesis. With the exception of non-chiral glycine, they all exist naturally as the L-stereoisomeric form, which is not to say they are all laevorotatory, but ...
