Could you locate a central of expansion

1 answer:

6 0

There is no centre of the expansion, the universe is simply expanding at all points. Observers in any galaxy see most of the other galaxies in the universe moving away from them. The only answer to the question "Where did the Big Bang happen?" is that it occured everywhere in the Universe.

What happens during the initiation step of DNA transcription? A ribosome attaches to the initiation codon of a completed mRNA st

Amanda [17]

Answer:

A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.

Explanation:

Transcription is the process in which DNA template is used to synthesize mRNA.

There are three steps of transcription:

Initiation

It is the process in which a portion of DNA unwinds and RNA polymerase binds to the promotor region on the DNA.

Elongation

It is the process in which RNA polymerase moves along the DNA template and synthesizes mRNA. During this process, unwinding of double stranded DNA takes place.

Termination

As the RNA polymerase moves along the DNA template, it finally reaches a termination signal and then stops synthesizing. It is followed by the detachment of the newly formed mRNA and RNA polymerase from the DNA.

QUESTION:

A ribosome attaches to the initiation codon of a completed mRNA strand.

This is the incorrect answer choice as this process does not happen in the process of transcription. This event happens in the process of translation in which mRNA is used to synthesize proteins or amino acids. mRNA attaches to ribosome during this process.

RNA polymerase moves along the template strand of the DNA creating an mRNA strand.

This is the incorrect answer choice as this event takes place in the process of elongation.

A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.

This is the correct answer choice as this event takes place in the process of initiation of transcription

The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand.

This is the incorrect answer choice. This event takes place in the event of termination of transcription.

The biological species concept is least relevant to which of the following groups of organisms?

Luba_88 [7]

<h2>b) is the correct option </h2>

Explanation:

The biological species concept defines a species as a group of individuals living in one or more populations that can potentially interbreed to produce healthy, fertile offspring

The biological species concept connects the idea of a species to the process of evolution
Because members of a species can interbreed, the species as a whole has a common gene pool, a collection of gene variants
In order to be considered to be a single species in the biological species concept, a group of organisms must produce healthy, fertile offspring when they interbreed
In some other cases, organisms of different species can mate and produce healthy offspring, but the offspring are infertile, can’t reproduce

Hence it includes the groups which are reproductively isolated so asexual fungi will be least relevant to this group

The one that makes the most sense to me, would have to be B. A would not be a benefit at all. While C doesn't necessarily makes sense as the device is only designed to capture energy from ocean waves. And D doesn't make sense to me in general.
