A eukaryotic gene contains 14 exons. Most of the transcripts from this gene contain all 14 exons, but some contain only 11 exons

. Only the 14-exo mRNA encodes a protein that changes its cellular localization in response to phosphorylation. Which mechanisms for producing complexity are exemplified by this gene? Check All That Apply A. DNA-level comblnatorial amplification B. pseudogene formation C. gene duplication and divergence D. alternative splicing E. posttranslational modification

Answer:

D. Alternative splicing is the mechanism that produce complexity in the genes by splicing some of the protein coding part (exons) of a genes

Explanation:

There are certain splicing enhancers sites present in Exons which facilitiates the binding of RNA binding protein specifically SR protein family rich in Serine and Arginine residues. This SR protein will help in splicing of exons.

The significance of this type of mechanism is the ability of a cell to produce an isoform of protein which have retain their function.

This mechanism also help is diversity or in short in evolution.

DENIUS [597]

Answer:

forming

Explanation:

Team development is a process wherein different individuals come together and learn to work efficiently to carry out a specific task.

There are certain stages that a team goes through during the development phase and these are:

1. Forming

2. Storming

3. Norming

4. Performing

5. Adjourning

The stage of team development where the different members get to know each other and orient themselves concerning each other's space is known as forming. This is a stage where they get acquainted with each other and explore and learn the ideas fo different team members.

Since in the given situation the scientists and dentists are holding a team meeting to get acquainted with each other and formally introducing themselves, the team is currently in the development stage of forming.

Grace [21]

Answer:

Carbohydrates.

Explanation:

Carbohydrates are very essential food nutrients that meet out our entire cellular energy requirement. They play a special role of providing energy during exercise and are commonly found is grains (wheat, rice) , fruits, vegetable, milk products and beans. They make human being sharper and provide energy for all their metabolic process with in the body.  

Carbohydrates are broken down into simple sugar molecules such as glucose, fructose, and galactose.

Why is it necessary for each gemete to contain only half as many chromosomes as a body cell
PilotLPTM [1.2K]

Answer:

This is for the offspring to show traits that come from both the mother and father.

Explanation:

Gametes are formed by a kind of cell division called meiosis in which the chromosome number is halved. Thus the said gamete cell is said to contain a haploid number of chromosomes.

The fusion of two haploid gametes is called fertilization. It results in the formation of single celled zygote which has a diploid number of chromosomes. The zygote now divides and develops to produce the offsprings whose somatic cells are diploid.
