<h2>Answer:</h2>
Bacteria provide genetic engineers with <u>_vector_ </u>and <u>_host_.</u>
<h3>Explanation:</h3>
Vector are vehicles or carriers which are used to carry the gene of interest. They are usually plasmids which are bacterial circular genome which can replicate independently.
Hence bacterial plasmids are used for the insertion of gene of interest and its transfer to the host cell.
As plasmids is taken from the bacteria, so mostly bacteria is used as the host for the gene of interest.
Answer:
Option 4
Explanation:
Folate is vitamin B and occurs naturally in various food items such as green leafy vegetable, lentils, peas, beans, in fruits such as banana, melon, and enriched products such as bread, juices etc. Folate is essential for making up genetic material or DNA. Out of all given options, option 4 has both lentil and spinach (green leaves) which are rich source of folate. Option 1 has bread as a source of folate. Hence, the correct answer is option 4.
Answer:
64
Explanation:
Since the population is in Hardy-Weinberg equilibrium and the equilibrium is defined by the equation
p² + 2pq + q²
where the frequency of the homozygous dominant allele F ( feathers on the leg ) = p²,
F of homozygous ( featherless legs) = q²
F of heterogyous ( carrier of featherless allele) = 2pq
F (q²) = 128/200 = 0.64
q = √0.64 = 0.8
and p + q = 1
p = 1 - 0.8 = 0.2
2pq = 2 × 0.2 × 0.8 = 0.32
number of chickens that are heterozgous for the feathered leg allele = 0.32 × 200 = 64
idk sry I don’t want to give u wrong answer
