Answer:
The answer is letter C.
Explanation:
The spliceosome can not excise RNA sequences bounded by an upstream 5' splice site and a downstream 3' splice site.B
Because it is not possible to produce an mRNA with the composition Exon 1 Intron AExon 3, it would require the use of two 3' splice sites.
Answer:
yy
Explanation:
it can only be yy because you need 2 recessive genes to show a recessive trait.
A plant with Yy genes could pass the recessive genes on, but would still show the dominant trait.
The nucleotide sequence on a section of
DNA where transcription begins is called a promoter.
To add, i genetics, a promoter is a region
of DNA that initiates transcription of a particular gene. Promoters are found along
the transcription beginning sites of genes, on the same strand and upstream on
the <span>DNA.</span>
Answer:
An organism would not be able to reproduce without meiosis.
Explanation:
Between meiosis and mitosis, meiosis is by far not as important. If you are a asexual organism, this would be NOT IMPORTANT whatsoever. If you are a sexual organism, this would LARGLY effect you. But on a world scale, this is NOT AS IMPORTANT.
This is because, without mitosis, you could not heal and would die much much younger since your cells could not be replaced. On the other hand, without meiosis, any organism that reproduces sexually would be unable to do so, which could lead to extinction in many, many species. This would not be harmful, however, to species that can also or mainly reporuduce asexually through budding, fragmenting, or sporing. So overall:
<u>Organisms that produce sexually would go extinct. </u>
This is the only real affect I can think of. Since meiosis does not produce any cells aside from reproductive cells. And asexual organisms produce reproductive cells through other means.
