Use the drop-down menus to answer the questions about genetic recombination. involves the transfer of genetic material from one
Tresset [83]

The right matches are:

• Involves the transfer of genetic material from one bacteria to another ==> Genetic recombination (all 3).

• Involves scraps of genetic material ==> Transformation.

• Uses a virus to transmit genetic material ==> Transduction.

• Uses a pilus to transmit genetic information ==> Conjugation.

• Introduces new genetic material to a bacterium ==> Genetic recombination (all 3).

In molecular biology the term genetic recombination is often used as a synonym for DNA recombination, that is, the processes by which one DNA (or RNA) molecule is cut off, then joined to another.

There are three possible mechanisms in the bacterium: bacterial conjugation, bacterial transformation and transduction.

bixtya [17]

Answer: 60%

Explanation:

In population genetics, the Hardy-Weinberg Principle states that the genetic composition of a population remains in equilibrium as long as no natural selection or other factors are active and no mutations occur.

The frequencies of the genotypes of an individual locus will be set to a particular equilibrium value.<u> It also specifies that these equilibrium frequencies can be represented as a simple function of the allelic frequencies at that locus</u>. In the simplest case, with a locus with two alleles A and a, with allele frequencies of p and q respectively, the principle predicts that <u>the genotypic frequency for the dominant homozygous AA is p^2, that of the heterozygous Aa is 2pq and that of the recessive homozygous aa, is q^2. The allele frequency of a is represented as p and the frequency of recessive allele is q.</u>

The three genotypes AA : Aa : aa appear in a ratio p² : 2pq : q². If we add them up, we get the unit:

p^2 + 2pq + q^2 = (p + q)^2 = 1  

And p + q = 1

<u>Rh-positive genotypes are represented as AA (homozygous dominant) or Aa (heterozygous) since the presence of a single dominant allele is sufficient to express the phenotype. While Rh-negative genotypes are represented as aa. </u>

If 84% of the population is Rh-positive, that means that this percentage includes all those who are AA and Aa. Then 16% are aa.

F(aa)=q^2=0.16

then F(a)=q=0.4

And since p + q = 1, p + 0.4 = 1, then p is 0.6

We can also calculate the rest, then F(AA)=p^2= 0.36

So F(Aa)= 2pq = 2 x 0.6 x 0.4 = 0.48

Notice that 0.36 + 0.16 + 0.48 = 1

How many organelles are in plant cells? please list them. :)
Murrr4er [49]
There are 11 organelles in total, 
vacuoles: they store water
Chloroplasts: trap energy from the sun to produce food for plant cell
Cell wall: provides support and protection to the cell membrane, 
Cell membrane: thin flexible barrier around a cell, controls what enters/ leaves the cell
Nucleus: 'The control center', carries the DNA of the cell
Ribosomes: Found in all cells, their jobs are to make protein 
Endoplasmic Reticulum: The internal delivery system of the cell
Golgi complex: Transports materials throughout the cell
Lysosomes: Break down food into particles the cell can use. another function is they destroy old or dying cells 
Mitochondria: Breaks down food to make ATP 
and last but not least cytoplasm a jelly like fluid in the cell that keeps the organelles suspended
