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.
Answer:
In the electromagnetic spectrum, the visible spectrum is the part, which is perceptible to the human eye. The electromagnetic spectrum in this array of wavelengths is known as simply light or the visible light. A general human eye will react towards the wavelengths in the range between 380 to 740 nm. A human eye sees the sky as blue that comes in the wavelength 490 nm because of the scattering of the visible light by the particles in the atmosphere. This concludes that 490 nm is the sole wavelength, which is reaching the eye.
I’m pretty sure it’s four chromosomes if it’s correct please at-least consider giving brainliest:)
Answer: coral reefs act as a filtering system .
Explanation:
Answer:
The answer is 1/4 of the offspring will have solid color, 3/4 of the offspring will have black fur, 3/4 will probably have colored fur, and 1/4 of the mice offspring wil probably have pieblad, or white patches. The combined probability is 1/4 X 3/4 X 3/4 X 1/4 = 9/256.
Explanation:
Because each gene segregates independently, so you need to determime the probability of each genotype independently and then multiply the four probabilities together. The probability of offspring with solid color (aa) is 1/4; the probality of offspring with black fur (BB or Bb) is 3/4; the probability of colored fur (Cc or cc) is 3/4, and the probability of piebald, or white patches(pp), is 1/4. The combined probability is 1/4 X 3/4 X 3/4 X 1/4 = 9/256.
