What is the concept of DNA?

Which carbohydrates are found in our genetic material?

Kisachek [45]

The carbohydrates found in our genetic material are the two sugars deoxyribose and ribose.

Carbohydrates are defined as organic compounds which occur in food and living tissue and include starch, sugars and cellulose. They are composed of hydrogen, oxygen and carbon.

Deoxyribose is a sugar found in the structure of DNA, while the sugar ribose is found in the structure of RNA.

DNA is the molecule that carries the cell's genetic information while RNA is the molecule involved in synthesis of protein using the coded information received from DNA.

Both DNA and RNA are termed as the genetic molecules of life.

Write an essay on ecosystem productivity

rosijanka [135]

A ecosystem productivity is a rate of generation of biomass.’’I know this because it states.”In economy productivity refers to the rate of generation of biomass in an economy.This shows that the economy its usually expressed in units of mass per unit.

What is the most role of hydrogen bonding between water molecules?

blondinia [14]

In a water molecule (H2O), the oxygen nucleus with +8 charges attracts electrons better than the hydrogen nucleus with its +1 charge. ... The hydrogen atoms are not only covalently attached to their oxygen atoms but also attracted towards other nearby oxygen atoms. This attraction is the basis of the 'hydrogen' bonds.

In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another

aev [14]

Answer:

15

Explanation:

The genes for vestigial wings (vg) and purple eyes (pr) are linked on the same chromosome.

The following cross was made:

Heterozygous male for both genes X female vg pr / vg pr

The male could be either vg+pr+/vg pr or vg+ pr/vg pr+.

The female only produces vg pr gametes.

The following offspring was observed:

420 Normal wings and red eyes (vg+ pr+/vg pr)

430 Vestigial wings and purple eyes (vg pr / vg pr)

80 Vestigial wings and red eyes (vg pr+ / vg pr)

70 Normal wings and purple eyes (vg+ pr / vg pr)

Total: 1000

The individuals observed in the highest frequency have the parental genotypes. The recombinant individuals are vg pr+ / vg pr and vg+ pr / vg pr.

Distance = Number of recombinants × 100 / Total

Distance = (80 + 70)×100 / 1000

Distance = 15 cM.

Just a small note, male drosophila do not experience crossing over in meiosis, so there would be no recombinants observed from this cross. The problem is probably mixed up, the female should be heterozygous and the male the homozygous recessive.
