Answer: last answer option
Explanation:
D - prophase - you can see this by the movement of centrosomes
A - metaphase - lining of chromosomes on metaphase plate
B - anaphase - splitting of sister chromatids
C - cytokinesis - formation of 2 new cells
the correct order is D A B C
Answer:
35%
Explanation:
If two genes are 30 map units apart, 30% of the produced gametes will be recombinant.
A mating between an individual homozygous dominant for both traits (AB/AB) and one homozygous recessive for both traits (ab/ab) is conducted.
The F1 will be heterozygous for both genes: AB/ab.
The F1 progeny is then test-crossed to a homozygous recessive individual:
<h3>AB/ab X ab/ab</h3>
<u>The possible offspring will be:</u>
- Parental (70%): AB/ab and ab/ab
- Recombinant (30%): Ab/ab and aB/ab
Since 30% of all the gametes produced by the F1 individual will be recombinant, 70% will be parental. As there are two types of parental gametes, each of them will have a frequency of 35%.
<u>The offspring that will have a dominant phenotype for both traits has the genotype AB/ab with a proportion of 35%.</u>
Answer:
The technique that is used in inserting a gene into a crop is genetic modification.
What is genetic modified crop?
A genetically modified organism (GMO) is a living organism whose DNA has been altered using genetic engineering techniques.
Humans have used breeding methods to modify organisms for thousands of years. Over generations, corn, cattle, and even dogs have been selectively bred to have certain desired traits.
The majority of GMO crops grown today were developed to assist farmers in preventing crop and food loss and controlling weeds.
The following are the most common traits found in GMO crops: Resistance to certain harmful insects, and Tolerance to certain weed-controlling herbicides.
Thus, with the help of genetic modification, a gene that controls beta-carotene production can be successfully inserted into a common food crop.
Answer:
Kerb cycle
<u>Explanation</u>:
The result from mitochondria is ATP, that acts as a currency of the energy in the cell. In the cytoplasm of mitochondria kerb cycle occurs. In this process it has several other process, once it uses acetate and water to give NADH from NAD+ and gives carbon dioxide as waste. The NADH formed is fed by oxidative phosphorylation or electron transport. The outcome of these processes is oxidation of nutrients to give chemical energy in ATP form.
