In the snail pomacea patula catemacensis, n = 13. what is the diploid number for this organism?

1 answer:

5 0

Answer: 26 chromosomes.
The diploid number is the number of chromosomes required for two sets of copies of the organism’s genome ( this is the number of chromosomes in the cells except gametic cells). The organism's genome is represented as n, and the diploid number,as 2n (2 x 13= 26).

A particular triplet of bases in the template strand of DNA is 5' AGT 3'. The corresponding codon for the mRNA transcribed is __

earnstyle [38]

Answer:

The correct answer is 3' UCA 5'

Explanation:

The rule of pairing of base-pair says that A and T base pairs with each other with two hydrogen bonds and G and C base pairs with each other with three hydrogen bonds in DNA. In the case of RNA Uracil comes at the place of thymine that means uracil replaces thymine.

Therefore according to this base-pairing rule the corresponding codon of mRNA transcribes from DNA codon 5' AGT 3' will be 3' UCA 5' as U came in place of A nucleotide, C comes in place of G nucleotide, and A comes in place of T nucleotide.

Therefore the correct answer is 3' UCA 5'.

Prepare a pamphlet on the problem of population growth

Goryan [66]

Answer:

problems of population growth are

economic causes
economic status
Poverty status
Occupational status
Unemployment

Explanation:

1. Economic causes : the economy always affect the fertility rate of any country. parents in backward communities considered their children as sources of income in future. most of these parents think that producing more children is helpful addition to the workforce and a means to increase the agricultural production.Economic causes refers to those aspect of our life that affect the population size from economic point of view.

2. Economic status: number of children are more in agro based communities. economic status also increase the population.in agricultural countries like I was all the works are done manually so more level forces are working people are required. farmer think that if they have large family they will accomplish their works easily and they will not have to hire people. they will be able to save the unnecessary cost . In other words ,the polar parents give birth to many childrens. it helps to increase the population.

3. Poverty: Poverty is another important factor of population growth in every country.many people of their country are under the absolute poverty line.they think that the birth of a son is the prospect of income in the family and he will drive them away from the poverty-stricken life.earn more money to wipe out their poverty. similarly, many pop people are deprived of even basic needs. education becomes an additional need to them. Then, the same vicious circle of illiteracy binds them within the same boundary of inner ignorance and poverty. Therefore,poverty plays an important role to increase the population of any country.

What is the answer of the question?

Goshia [24]

Answer:

A. Amino Acid, protein, gene.

Explanation:

Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.

A gene can be defined as a complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Simply stated, a sequence of biomolecules which are responsible for coded genetic instructions in all living organisms is known as nucleotides.

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

Furthermore, the two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

Additionally, the proteins which are mainly synthesized based on the genetic instruction codes in deoxyribonucleic acid (DNA) determines the trait of living organisms.

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

Hence, when you remove a nucleotide from a gene, the order of nucleotides shifts and as such resulting in new amino acid being coded for. These new amino acid will combine to form a different protein than what the gene was originally coded for.
