Q: Explain The Elements of Prokaryotic Gene Expression?

Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
Name one step of gene expression and describe one way that step differs between prokaryotes and eukaryotes.
Step by step

- Create a Venn diagram to compare and contrast the process of gene expression in Bacteria versus eukaryotes. Remember that “gene expression” can include any part of transcription or translation. Try to be as thorough as you can about what aspects of this process are similar between the two taxa, and what characteristics are distinct to only Bacteria or eukaryotes. Plase include a minimum of 15 items in the Venn diagram.Put the following processes in order of their occurrence during expression of a eukaryotic gene: a. mRNA processing c. transcription b. translation d. RNA leaves nucleusMany aspects of gene function can be nicely explained with the one-gene-one-enzyme hypothesis, which states that a gene controls the production of an enzyme. Which of the following findings about gene expression, though, requires an expansion of this simple concept? Choose an answer below: Non-enzyme proteins are made from genes too. Some genes code for RNA molecules only. Enzymes composed of different polypeptides are coded for by more than one gene. a and c, but not b a, b, and c

Enzymes composed of different polypeptides are coded for by more than one gene. a and c, but not b a, b, and cSeveral different nucleic acids are involved in the process of getting a protein produced from a gene. DNA contains the "genetic code" for the protein. DNA is double-stranded, but only one strand is transcribed into MRNA. The MRNA then goes into the cytoplasm where it is translated into protein with the help of TRNA. At each stage of the process, there is base complementarity (A pairs with T/U and C pairs with G) between the nucleic acids involved to ensure the integrity of the DNA blueprint for the protein being produced. Therefore, some of the four strands of nucleic acids involved will match (except U replaces T in RNA) and some will have base complementarity. Indicate whether there is matching (1) or base complementarity (2) between the following nucleic acids. DNA sense strand and MRNA DNA sense strand and tRNA DNA antisense strand and MRNA MRNA and TRNAFor each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; use each word or phrase only once. For a cell's genetic material to be used, the information is first copied from the DNA into the nucleotide sequence of RNA in a process called . Various kinds of RNA are produced, each with different functions, as follows: molecules code for proteins, molecules act as adaptors for protein synthesis, molecules are integral components of the ribosome, and molecules are important in the splicing of RNA transcripts. incorporation FRNA translation MRNA snRNPs transmembrane PRNA transcription TRNA protein
- a) Define the term gene expression b) State 4 difference between prokaryotes and eukaryotes gene expression c) state the importance of regulating gene expressionThe diagram below shows the structure of DNA from the level of a gene to a condensed mitotic chromosome. At each of the four locations marked, indicate how a gene may be regulated by selecting from the choices given. Some answer choices may fit into more than one position; however, you should use each answer choice only once. Choices given: Alternative splicing within the gene sequence can lead to different forms of mRNA. A promoter region can be blocked by another protein. Histone deacetylation can prevent DNA from unwinding. A regulatory region can be bound and increase transcription rates.Consider Molecule X, which is found in all living cells. This molecule is transcribed from a stretch of DNA in the nucleus. Each nucleobase on the DNA produces a matching nucleobase on this molecule. Every 3-base codon specifies an amino acid in a protein. What is the name of X? Your answer should be one word, or a short two- or three-word phrase. Spelling counts. Note: if there is more than one possible answer, separate each answer with a comma. x 5
- A) List the steps for gene expression in prokaryotes and eukaryotes. B) Relate the differences in gene expression between prokaryotes and eukaryotes in gene expression regulation and explain what causes those differences.What is a gene? What does "base sequence" mean? If the base sequence of a segment of a molecule of DNA is changed, will the base sequence of the mRNA made during transcription be changed? If the base sequence of the mRNA is changed will the sequence of amino acids obtained during translation change? If the primary structure of a protein is changed, will it's function change? If the function of the protein changes, will the organism have a different characteristic? Do introns get read during translation?asap please A partially filled diagram of eukaryotic gene structure is shown below. Label the following additional elements in the empty boxes.
