5) In Ligers, stripes are dominant over solids. If two heterozygous Ligers mate
VikaD [51]

The chance of their baby liger having stripes and being solid would be 3/4 and 1/4 respectively.

<h3>Monohybrid cross</h3>

Assuming stripes allele to be A and solid allele to be a.

For two heterozygous ligers, Aa   vs   Aa

                             Aa    x    Aa

                           AA   Aa   Aa   aa

Offspring

AA and Aa - striped = 3/4

aa - solid = 1/4

Thus, the chance of producing a striped baby is 3/4 while the chance of producing solid baby is 1/4

You are doing research in bacteria on the effects of mutating the shine-dalgarno sequence. you change some nucleotides in the sh
padilas [110]
<span>Shine-Dalgarno sequence is a sequence that precedes the starting codon in the mRNA. the small sub-unity of ribosome will recognize it with by a specific sequence in the initiation phase of translation.

The best way to restore the translation speed if the Shine Dalgarno sequence is mutated is to make a change in the small sub-unity of the ribosome, specifically in the RNA sequence that recognizes the mRNA Shine Dalgarno sequence, so it can be recognized again. and the translation process will be restored.
</span>Another way to improve a translation speed if to provoke a mutation in the proteins' genes involved in the translation process (like enzymes and translation factors), there will be a chance to increase their effectiveness, especially for enzymes, so the translation speed will be improved.

This hypothesis states that viruses originated from more complex cells<br> Select one:
-Dominant- [34]

Answer:

The hypothesis that states that viruses originated from more complex cells is called the regressive hypothesis.

Explanation:

The regressive hypothesis -also called <u>degenerative hypothesis</u>- raises the possibility that viruses originally were cells that behaved as symbionts or parasites of other cells, and this condition of dependence could have originated the disappearance of genes, becoming structures formed by nucleic acid inside a viral capsid (virus).

Some evidence gathered to support this theory suggests that some bacteria, such as rickettsia, need to parasitize a cell in order to replicate, just as viruses do.
