In genetics, a promoter is a sequence of DNA to which proteins bind to initiate transcription of a single RNA transcript from the DNA downstream of the promoter. The RNA transcript may encode a protein, or can have a function in and of itself, such as tRNA or rRNA.

What is the hardy weinberg symbol for the dominant allele
soldier1979 [14.2K]

Answer:

The Hardy Weinberg symbol for the dominant allele is 'p' in his equilibrium equation.

Explanation:

  • The equation given by Hardy: "\bold{p^{2}+2 p q+q^{2}=1}" is known as "Hardy-Weinberg equilibrium equation".
  • The frequency of dominant allele and recessive allele for a trait is represented by 'p' and 'q' respectively.
  • 2pq in the equation is the frequency for heterozygous  genotype.
  • Conditions that must be considered for the Hardy-Weinberg equilibrium equation to satisfy are: no mutations , no flow of gene, large population size, no selective forces , no non-random mating.

Please answer these questions I'll give 40 brainliest and you will help me so much
Kisachek [45]

Answer:

10:  Number of protons always equal number of electron, but that's the case with a neutral atom. ... This implies that it has same number of protons and electrons in it. It means it has same amount of positive and negative charge, which cancel each other, and the atom as a whole becomes electrically neutral.

19: The three stable isotopes of Argon, Argon-36, Argon-38, and Argon-40, would all have 18 protons and 18 electrons if they are all neutral. The three isotopes will have different numbers of neutrons compared to each other (18, 20, and 22 neutrons respectively).

20: This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.

Explanation: Hope those are the only answers you needed. I just saw the stars next to them and figure those were the only ones you needed.

Zanzabum

Mutation rate of Gram negative bacteria is much greater than that of Gram positive bacteria.

Explanation:

The gram positive types of bacteria responsible for causing diseases in humans. It is called as Gram positive bacteria. Both the bacteria are different in structural and physical properties. It is defined as the group of bacteria’s which positive result in gram stain test.

Gram negative bacteria are the group of bacteria’s which gives negative result to the gram stain test. This classification is done according to the cell wall. The cause of common disease by Gram positive bacteria is our anthrax, diphtheria, etc.
