Continental drift is the process that powers the movement of tectonic plates. The movement of magma can also attribute to this movement as well.

Which of the following features of the trp operon is most essential to the process of attenuation independent of the repressor p

diamong [38]

Answer:

The ability of sequences within the leader mRNA to pair with one another and form stem-lopp structures

Explanation:

A form of feedback regulation controls the trp operon by regulating transcription termination, a mechanism referred to as Attenuation.

-In the presence of high concentrations of tryptophan, RNA polymerase ceases transcription shortly after initiation in a region called the leader sequence.

-If the concentration of tryptophan is low, transcription does not terminate until the entire operon is transcribed. The mechanism of attenuation links alternative RNA secondary structures to transcription termination.

-Immediately after transcription, RNA from the leader region folds into one of two alternative secondary structures.

-One of these structures is a transcription termination signal that stops RNA polymerase from continuing to the end of the operon.

-The alternative structure does not contain a transcription termination signal and allows transcription of a single mRNA that encodes all the structural genes.

-The decision as to which of the two alternative RNA structures formed is regulated by the concentration of tryptophan.

In DNA replication, the resulting daughter molecules contain one strand of the original parental DNA and one new strand. What is

Dmitriy789 [7]

Answer:

This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.

Explanation:

Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).
