Describe the role of RNA polymerase in the transcription process. What occurs during the termination stage of DNA transcription? Explain the differences between transcription and translation. 1- What is the purpose of the mRNA transcript? 2- Explain why term 'transcription' is used to describe this...
Describe the structure of chromosomes and the role of structural packaging and organization of DNA. Describe the function of DNA polymerase I in leading strand synthesis in DNA synthesis. Describe the contents of the bacterial nucleoid and summarize the packing of the DNA and chromosome within the ...
Here we tested the possible role of DNA methylation in mediating long-term induction of epileptiform activity by transient kainic acid exposure using in vitro and in vivo rodent models. We analyzed changes in the gria2 gene, which encodes for the GluA2 subunit of the ionotropic glutamate, alpha...
Describe how the concept of heritability has been misused in the debate over group differences in IQ test scores. Heritability: Heritability is a measure of how differences in people's genes (genotypes) affect differences in people's traits (phenotypes). A br...

Honey bees are large-scale monitoring tools due to their extensive environmental exploration. In their activities and from the hive ecosystem complex, they get in close contact with many organisms whose traces can be transferred into the honey, which can
DNA | Definition, Characteristics & Sequencing from Chapter 4 / Lesson 1 123K Learn about DNA, or deoxyribonucleic acid, and how it is one of the major components of living organisms, playing an important role in all of life's processes. Related...
Explain, in general terms, the role of RNA in gene expression. Why is RNA useful to a cell? What is the benefit of using RNA instead of just directly producing protein from the instructions in DNA? Explain the differences between DNA and RNA. ...
Briefly identify and describe the stages of interphase and mitosis. Explain the process of mitosis. Describe the difference between a gene and a codon. Explain what is DNA and how it encodes genetic information Explain the role of tRNA in protein synthesis. Include a description of how it inter...
