Answer:

melanopsin

Explanation:

this note might help you :

The retinohypothalamic tract (RHT) is a photic neural input pathway involved in the circadian rhythms of mammals. The origin of the retinohypothalamic tract is the intrinsically photosensitive retinal ganglion cells (ipRGC), which contain the photopigment melanopsin. The axons of the ipRGCs belonging to the retinohypothalamic tract project directly, monosynaptically, to the suprachiasmatic nuclei (SCN) via the optic nerve and the optic chiasm. The suprachiasmatic nuclei receive and interpret information on environmental light, dark and day length, important in the entrainment of the "body clock". They can coordinate peripheral "clocks" and direct the pineal gland to secrete the hormone melatonin.

information about melanopsin : Melanopsin is a type of photopigment belonging to a larger family of light-sensitive retinal proteins called opsins and encoded by the gene Opn4.[5] In the mammalian retina, there are two additional categories of opsins, both involved in the formation of visual images: rhodopsin and photopsin (types I, II, and III) in the rod and cone photoreceptor cells, respectively.

PolarNik [594]

Answer:

Minimal media + glucose + streptomycin

Explanation:

Those capable of synthesizing galactose can grow in minimal media, the availability of streptomycin will destroy those who are susceptible to the antibiotic, whereas glucose, a carbon source from which galactose may be produced and will encourage growth.

Therefore:

The medium should not include galactose when selecting for gal⁺.

Streptomycin should be present in the medium to select against str^s.

The medium to choose is: Minimal media + glucose + streptomycin.

Answer:

The phenotype of the brown parent would be heterogeneous.

Explanation:

As albino is a recessive trait, both the alleles should be recessive for this trait to occur.

A punnet square is a diagram which is made to illustrate the possible phenotype of the offspring.

If the brown parent will be homologous, then a cross with albino parent  will produce offspring with brown color having heterogeneous phenotype.

For production of albinos the brown parent should be heterogeneous for the trait.

Arrange the following in the proper sequence in which they occur during a single PCR cycle.
Tju [1.3M]

Answer:

C. 3, 2, 1

Explanation:

During a single PCR cycle, the very first step is the heat separation of the double stranded DNA. Primer binds only single stranded DNA/RNA because it has complimentary bases which match single strand of DNA/RNA that is why it is necessary to unwind both the strands of DNA by providing temperature.

As soon as the DNA strands have separated by increasing the temperature to ~ 95 °C, in the next step the primer binds the portion of DNA which is complimentary to the bases of the primer. In order for primer to bind DNA, the temperature is lowered to ~ 72 °C and the process is called as annealing.

Once primer has bound to the DNA, the next step is polymerization i.e. nucleotides which are the monomer units of DNA are added one by one with the help of enzyme named as Taq polymerase. This is how the strand extends ahead of primer and exact copies of the given DNA are produced.

Note: PCR may be considered as in vitro DNA synthesis or replication.
