In the trp (tryptophan) operon, the* repressor protein *binds to the product of the trp operon synthesis pathway, called *tryptophan *forming the active *corepresser *
The reason why the RNA has decrease stability compared to
DNA is because the DNA, is lacking a hydroxyl group in which making it more
stable than of the RNA, that is why RNA has decrease stability than the DNA.
Answer:
The virus will transfer the DNA encoding cholera toxin to the next bacteria it infects, which will make that bacteria cholera-causing.
Explanation:
The process described in this question is a kind of gene transfer in bacteria called TRANSDUCTION. Transduction is the transfer of fragments of DNA from one bacterium to another via a virus called bacteriophage.
As stated in this question, the virus (bacteriophage) infects a cholera-causing bacterium. The bacteriophage moves from lysogenic cycle to lytic cycle and includes some pieces of the bacterial DNA, which encodes information for making the cholera toxin, in its own genome.
This means that the cholera-making toxin DNA is now a part of the virus's genome and hence, will transfer it to the next bacteria it infects in a process called TRANSDUCTION. This will make that bacteria a cholera causing bacteria.
If we talk about guinea pigs, the trait of hair length is controlled by a gene with two alleles.
Allele for short hair (S) is dominant on the allele for the long hair (s).
The texture of hair texture is controlled by a gene with two alleles. It can be rough or smooth, and the allele for rough hair (R) is dominant on allele for smooth hair (r).
Now coming towards the question:
- A female guinea pig is heterozygous for hair texture and homozygous recessive for hair length.
Phenotype of the female will be Rough and long hair.
- A male guinea pig is homozygous dominant for hair texture and hair length.
Phenotype of the male will be Rough and short hair.
