SCNT stands for Somatic Cell Nuclear Transfer. It is used for creating an ovum with a donor nucleus. It can be useful in embryology and a donor nucleus.
The steps of SCNT are as following:
<span>d. Isolate donor cells from egg donor and germ cell donor
</span><span>c. Remove and discard the nucleus from the egg cell
</span><span>e. Transfer the somatic cell nucleus into the egg cell
</span><span>a. Stimulate cell division
</span><span>f. Implant embryo into a surrogate mother
</span><span>b. Deliver baby</span>
Explanation:
Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.
Answer: they grow bigger and stick together
Explanation:
The given question is incomplete as the option are not provided however, the correct options are as follows:
Defective proteins are often degraded quickly, making their effects temporary.
Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.
Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.
Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.
ch mRNA molecule is only translated once and then degraded
Answer:
The correct answer is - statements 1, 3, and 4.
Explanation:
DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.
RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited
The process of transcription is quick.
