The processes produce different proteins in different cells from the same primary transcript including "Alternative splicing" & "RNA editing"

What is Alternative splicing?

Alternative splicing is a departure from this intended pattern in which positive exons are skipped, leading to a variety of mature mRNA types.

What various forms of alternative splicing are there?

There are five main types of alternative splicing activity shown, - Constitutive splicing,

- Mutual exclusion of exons,

- Cassette alternative exons,

- Alternative 3′ splice sites,

- Alternative 5′ splice sites and intron retention are examples of splicing techniques.

The creation of numerous gene products from the most efficient single gene is enabled by the removal of introns and the reconnecting of exons in novel combinations to produce a series of mRNAs with novel functionalities.

Hence, the answer is Alternative splicing and RNA typing.

Which list represents the proposed sequence in plant evolution?

Phoenix [80]

Answer:

1. Bryofita

2. vascular plants

3. Seed vascular plants (gymnosperms)

4. Angiosperms

Explanation:

1. Bryofita

Around 475 million years ago, the origin of plants was thought to originate from aquatic ancestors (green algae). Adaptation to terrestrial life is proven by the presence of sporopolenin and layered gametangia that protect gametes and embryos. This adaptation occurs in bryophytes which are the first terrestrial plants. Bryofita or mosses develop into various vanations in their group. Most briolites do not have vascular tissue (water from the environment is diluted and absorbed by the SD, but some briophytes have water-carrying vessels.

2. Vascular plants

Around 400 million years ago, the evolution of plants was marked by the diversification of vascular plants (vascular plants). These early vascular plants are seedless plants, for example in the types of ferns seria into other groups of seedless plants.

3. Seed vascular plants (gymnosperms)

Plant evolution begins with the appearance of seeds, which are structures that protect the embryo from drought and the threat of environmental change. The emergence of these seed plants accelerated the expansion of plant colonization on land. Plant seeds consist of embryos and food reserves that are protected by a cover. Seed vascular plants appeared about 360 million years ago with the appearance of Gymnosperms. Gymnosperms consist of conifers with a variety of types. Conifers and ferns dominate life in the months between more than 200 million years.

4. Angiosperms

About 130 million years ago marked the emergence of flowering plants that have a somewhat reproductive structure

complicated where the seeds are protected by a room called the ovary.Because the seeds are protected in such a way that this group discusses closed seed plants or Angiosperms

Give the sequence of mRNA that would match the following DNA strand

sladkih [1.3K]

Answer:

Below

Explanation:

mRNA is a complimentary copy of a DNA segment (gene) and consequently can be used to deduce the gene sequence. For converting a sequence from mRNA to the original DNA code, apply the rules of complementary base pairing: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A).

The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain. The anticodon is the complementary three nucleotide sequence in the appropriate tRNA.

If a bacteria is positive for the enzyme urease and is inoculated in a urea reduction broth tube at 37∘C for 24 hrs, what color

Vedmedyk [2.9K]

Answer:

The color would be Pink

Explanation:

According to the question, the bacteria is positive for the enzyme urease and it's inoculated for 24 hours.

Urease broth is a differential medium that tests the ability of an organism to produce urease, that hydrolyzes urea to ammonia and carbon dioxide. The broth contains two pH buffers, urea, a very small amount of nutrients for the bacteria, and the pH indicator phenol red. Phenol red turns yellow in an acidic environment and fuchsia in an alkaline environment.

If the urea in the broth is degraded and ammonia is produced, an alkaline environment is created, and the media turns pink within 24 hours.

Many enterics can hydrolyze urea; but only a few can degrade urea rapidly. These are called “rapid urease-positive” organisms.

Urea broth is formulated to test for rapid urease-positive organisms. The restrictive amount of nutrients coupled with the use of pH buffers prevent all but rapid urease-positive organisms from producing enough ammonia to turn the phenol red pink.

Yes because there can sometimes have traits that aren't identical to the parents probably because of the ancestors (who have regular noses).
