Answer:
Transcription, mRNA (processing, transport, localization and stability), translation.
Explanation:
- Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
- mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
- In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

Answer:
Good question! Hamburgers actually get their name from Hamburg, Germany, home of a cut of beef called the Hamburg steak that eventually evolved into what we now consider hamburgers
<span>My pea plant has an unknown genotype for flowers, whether it has two dominant traits for white flowers (WW) or one dominant and one recessive (Ww) leading to white flowers; therefore I am doing a testcross in order to determine the genotype of my pea plant. The best plant to do this with is one that has a phenotype of purple flowers (ww) - that is, it is homozygous for the recessive trait.
If I use a homozygous recessive plant, I know exactly what its genotype is. I don't have to worry about whether it's got one or two dominant alleles; I know that at least half of my alleles are going to be the recessive w.
This makes identifying the offspring's genotype very simple. If I find that the offspring have at least some purple flowers among them, I know that my original plant had to be Ww; that is it had to have one dominant and one recessive allele for the flower color gene. If, however, all of the offspring are white flowers, I know that my original pea plant had both dominant alleles (WW).</span>
He used Pea plants to help him find the laws of inheritance. He crossed homozygous (AA) tall plants with short (aa) plants and found that all of the off spring were tall, due to the fact that tall is dominant and short is recessive. He then conducted another experiment where all the offspring mated (all offspring were heterozygous (Aa)) And produced the F1 generation and 25 percent of the plants were short (use a punnet square to see why) and 75 percent were tall.
I hope this response helped :) If u have anymore q about mendelian genetics pls lmk !
