I think its the first one but I'm not sure
Answer:
a. Bacteria cannot carry out splicing.
Explanation:
Human genes contain non-coding sequences called introns. Transcription of genes produces primary transcripts that undergo post-transcriptional modifications to produce mature mRNA. These modifications include removal of introns, the addition of 3' poly-A tail and 5' cap. The splicing of introns from primary transcripts is followed by ligation of protein-coding sequences exons to produce mature mRNA. The mRNA leaves the nucleus and serves as a template for protein synthesis.
Splicing of introns requires specific machinery such as several small nuclear ribonucleoprotein complexes, etc. which are not present in a prokaryotic cell. Therefore, a eukaryotic gene like the gene for human growth hormone is not expressed in a bacteria cell as these prokaryotic cells cannot carry out the splicing of introns from pre-mRNA.
Hey Brainly Student!
I found this in wonderopolis.org: “Scientists concluded that the average human body contains approximately 37.2 trillion cells! Of course, your body will have more or fewer cells than that total, depending upon how your size compares to the average human being, but that's a good starting point for estimating the number of cells in your own body!”
This is an estimation and there is not an exact amount because everyone is different :)
Just go with 78 as the answer
This is a law because the math behind it is simple and makes
sense – is scientifically proven and developed and is designed to be used. If
double the force, you have double acceleration, double the mass, you get half
the acceleration. A theory is an opinion or an idea, this is a law because it
is sound and the only law for this theme, it stands true for every scenario.
<span>a...it is a fixed equation that is true for
every scenario...</span>
