The purpose of the plasma membrane is to keep certain things and things out. So the correct answer to this questions is D, encloses specific structures.
Answer:
The short‑ear allele phenotypic ratio is 25%.
Explanation:
Genotype for homozygous short‑eared progenitor: ll
Genotype for homozygous long-eared progenitor: LL
Genotype for heterozygous: Ll
P) LL x ll
Gametes) L L l l
F1) LlLl
All of the individuals of the first progeny are long-eared heterozygote.
The cross of two heterozygous individuals:
Ll x Ll
Gametes) L l L l
F2) 25% Homozygote for the long ear: LL
25% Homozygote for the short ear: ll
50% Heterozygote: Ll
75% of progeny are Longed-ear animals
25% of progeny are Shorted-ear animals
Answer:
The answer is given below.
Explanation:
A tiny difference in a distant enhancer make a blond through DNA Looping.
DNA Looping can bring the enhancer bound by an activator physically closer to the promoter even if the enhancer is located far away along the DNA molecule.
DNA Looping.
When a protein or a set of complex proteins binds to 2 different sites of DNA simultaneously while looping out the interfering DNA.
Important of DNA Looping
- It regulates metabolism of DNA
- it is involved in transcriptional initiation of prokaryotic operons.
High shelf life apple and disease free banana are the two fruits that are being engineered to be healthier.
The yield, production and nutrition value of food can be improved by employing genetic engineering in the food production. This will solve the problem of food in countries where resources are scarce.
Explanation:
Genetic engineering is the process in which genes are altered or introduced in a particular organism or plant to create a useful trait.
The genetically modified foods have many advantages as no use of pesticides, long shelf life, high nutritious value and high yield.
The two fruits are:
Arctic apples are genetically modified so that they do not get brown after slicing. This healthier version of apple is a big step in preventing food wastage.
Banana plantations were suffering due to a disease fusarium wilt but GMO have resolved the issue and prevented the disease and increase its production.
The people of less privilege countries who continuously face famine and malnutrition can solve their food problem by using GM techniques. The yield and nutrition value can be increased manifold in the crops. Besides the crops would made to get ready in less resources to overcome famine conditions.
