Answer:
Awnser
Explanation:
The Awnser is C _________________
Answer:
D) presence of transcription activators or repressors
Explanation:
The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.
For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
Answer:
This means that one amino acid can be coded by more that one codon.
Explanation:
A triplet code that code for an amino acid during translation is called genetic code. The genetic code is said to be redundant because a single amino acid can be coded by more that one triplet codon.
So there can be synonymous codon for one amino acid. For example, leucine, serine, and arginine have 6 synonymous codons.
The genetic code is unambiguous also because each triplet codon can only code for a particular single amino acid. Genetic code is also universal which means the same code is used in all life forms.
A. The organism has a large nose, because it's homozygous.
The option that is an example of the "ethical dilemma" of creating and destroying human embryos is option A: Some people..."believe an embryo has the same moral standing as a human being?"
<h3>What moral dilemmas do embryonic stem cells present?</h3>
The infinite differentiation potential of iPSCs, which can be used for human cloning and pose a risk for the creation of human embryos and human-animal chimeras, is the center of the current ethical debates surrounding stem cell-based therapies.
However, due to the fact that it involves the killing of human embryos, hESC research is morally and politically contentious. The controversy over abortion has a strong connection to the issue of when human existence begins in the United States.
