How does RNA primase synthesize RNA primer? Explain how amino acids form proteins. In your explanation, consider different types of bonds that maintain the secondary, tertiary and quaternary structure of proteins. In what way does RNA polymerase differ from...
3.RNA polymerase is free to bind to promoter and initiate transcription of structural genes/lac Z and Y of the operon/switc on lac operon 4.Produces more permeas which increases rate of uptake of lactose 5.Produces more beta-galactosidase which will hydrolys lactose (b)(i)Operator(ii)1....
Since rotation of the nucleotide would disrupt the asymmetry, the optimal nucleotides must form two or more hydrogen bonds with their counterpart on the template strand. All nucleotides in modern RNA and DNA have these predicted properties. Our models demonstrate these constraints on the properties ...
Explain the process of translation in DNA. Describe the structure of RNA, the type of sugar it contains, and explain its bases. Explain the role of tRNA in protein synthesis. Include a description of how it interacts with mRNA and the ribosome. Describe DNA replication and which enzyme(s) ...
Explain how the structure of DNA is well-suited for replication and its function. What is the process of DNA replication? Explain the process of replication. Why does this process produce identical DNA strands? Explain step-by-step how DNA replication happens. ...
• Double-stranded DNA • Single-stranded RNA • Double-stranded RNA Let's assume that the linker DNA averages 254 bp in length (Nucleosome:~146 bp of DNA wrapped around a histone octamer). How many molecules of H2B would you expect to fin...

A recombinant protein is one that has been cloned into a vector that supports the transcription and translation of the gene. Recombinant proteins may be expressed in a host cell and purified for biochemical studies or therapeutic purposes. Alternatively, recombinant proteins m...
Genetic variants that severely alter protein products (e.g. nonsense, frameshift) are often associated with disease. For some genes, these predicted loss-of-function variants (pLoFs) are observed throughout the gene, whilst in others, they occur only at
The four nuclear bases on DNA are adenine (A), guanine (G), cytosine (C) and thymine (T). RNA has uracil (U) instead of thymine. A always pairs with G. C always pairs with T in DNA or U in RNA.Answer and Explanation:
