Answer:

DNA always has these bases: A,T,C,G whilst RNA always has A,U,C,G (RNA never has T).

C and G are complementary, so if your DNA has C, the RNA will have G.

If your DNA has T, your RNA has A

If your DNA has A, your RNA has U

^ These rules always hold true.

To find the proteins formed, take your codon (3 bases on RNA) eg AUG and look at the diagram. First look at the green A section, then the red U section and then the G section. Your protein will be abbreviated to 3 letters eg ala or gly.

Explanation:

Hope this helps you.

The main thing you need to know is which bases are complementary, and that RNA (mRNA and tRNA never have T, they always have either U or A, and C or G.

Explain the role of crossing over in terms of achieving genetically varied offspring

Annette [7]

Answer:

Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

A given mass of oxygen at room temperature occupies a volume of 500. 0 ml at 1. 50 atm pressure. what pressure must be applied t

andreev551 [17]

5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

<h3>Given</h3>

Mass of oxygen at room temperature =500.0 ml

Volume of pressure = 50 atm pressure.

The gas to a volume = 150.0 ml

<h3>Explanation</h3>

The volume decreases by the factor = 500.0 mL / 150.0 mL

= 10 / 3

The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to

$P_{final} = \frac{10}{3} * 1.50 atm$

= 5.00 atm

So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

What are some of the concerns associated with our increasing population and consumption of resources?

Ugo [173]

Explanation:

As human population increases the rate of consumption of resources also increases. Economists postulates that available resources with which to satisfy our unlimited wants as a population is highly limited.

Increase in population leads to an increasing pressure on available resources such as freshwater, land, air, energy e.t.c.
Increasing population easily leads to deforestation. Deforestation is the loss of forest. Forest trees are used in construction of houses and industries. Forests also takes up space and they might have to be plundered to make way for new buildings. Eventually, the forest will be lost.
Decrease in standard of living: increasing population will lead to a low standard of living. Resources meant to accommodate a certain number of people will no longer be sufficient for them.
High poverty rate; if population continues to rise, the rate of poverty will increase too. There will be limited resources to cater for the well being of the populace as a whole.
