Write out the steps in the Central Dogma. List where each step occurs in the cell. For each arrow, name the process that the arrow represents and the primary enzyme (complex) respon- sible for completing that step. Name the step(s) in which mRNA, tRNA, and rRNA have a role and briefly describe the role of each in the step(s) you name.

1. The Central Dogma refers to the molecular process by which the DNA is converted into proteins using RNA as intermediate, i.e., DNA (Transcription)-> RNA (Translation) -> Protein.

2. Localization:

Transcription: within the cell nucleus (in eukaryotic organisms)

Translation: cytoplasm

3. Enzymes :

Transcription: RNA polymerase

Translation: Peptidyl transferase

Explanation:

Transcription is the process by which a segment of DNA (called gene) is used as template to synthesize a messenger RNA (mRNA) by using a specific RNA polymerase enzyme. During translation, this mRNA travels from the cell nucleus to the ribosomes in the cytoplasm, where this sequence (mRNA) is used as template to synthesize a protein. The ribosomes are organelles composed of ribosomal RNA (rRNA) molecules which direct the catalytic steps of protein synthesis, while transference RNAs (tRNAs) are molecules that act as adaptors which link the mRNA template with the corresponding amino acids being incorporated into the protein. The enzyme peptidyl transferase catalyzes the formation of peptide bonds between adjacent amino acids.

Answer from: Quest

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat. although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. â€ścaptureâ€ť as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
