Which statement BEST explains how RNA polymerase knows where to start and stop making an RNA copy of DNA?
guapka [62]

"The enzyme only binds to regions of DNA known as promoters, which have specific base sequences" statement BEST explains how RNA polymerase knows where to start and stop making an RNA copy of DNA.

Option: D

<u>Explanation:</u>

Transcription is the mechanism which happens when polymerase of RNA (principal enzyme for transcription) attaches by aid proteins or personally or to a promoter segment near the gene beginning.

For generating a new molecule of RNA which is complementary, RNA polymerase utilizes one of the DNA strands or the parent strand as a template.

For an instance, trying to block mushroom toxicity transcription triggers liver failure and death, as no new RNAs and therefore no fresh proteins can be produced.

Find a start signal, and write the amino acid sequence that is coded for. 5'...gccauguuuccgaguuaucccaaagauaaaaaagag...3'
Greeley [361]
The start signal is AUG which codes fo methionine. The amino acid sequence will be as follows: <span>Met-Phe-Pro-Ser-Tyr-Pro-Lys-Asp-Lys-Lys-Glu. The first codon (GCC) codes for alanine but not in the amino acid sequence because it is not a start codon (the only start codon is AUG which codes for methionine).

Which of the following statements about plankton or nekton is NOT correct?
Oduvanchick [21]

Answer:

C. All plankton are closely related to plants.

Explanation:

Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.

Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.

Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.

Nekton are organisms found in water that swim actively.

Based on this information, we can conclude that statement C is the only incorrect statement.
