In the genes of eukaryotes, the rearrangement of exons to form new genes is termed as alternative RNA splicing. The alternative RNA splicing leads to formation of novel genes.

Answer 77

Summary Introduction

k.

To determine:

The phrase that describes “alternative RNA splicing” among the options given below.

1. a discrete part of a protein that provides a unit of function.

2. a nonfunctional member of a gene family

3. the joining together of exons in a gene in different combinations

4. most frequent residues, either nucleotide or amino acid, found at each position in a sequence alignment

5. set of genes related by processes of duplication and divergence.

6. chromosomal regions with same genes in the same order in two different species.

7. genes with sequence similarities in two different species that arose from a common ancestral gene.

8. genes that arose by duplication within species.

9. genomic DNA sequences containing exons.

10. gene-poor region of the genome.

11. recently evolved from intergenic DNA sequences.

12. progressive elimination of individuals whose fitness is low and survival of high fitness.

Introduction:

When joining of exons in a particular gene results in the production of different combinations, this process is called alternative RNA splicing.

Introduction:

When different combinations occurs due to rearrangement of exons, it is called protein domain.

Expert Solution

Answer to Problem 1P

Correct answer:

Protein domain: the joining together of exons in a gene in different combinations.

Explanation of Solution

When the linear amino acid sequences bend and function as a single unit, it is termed as the protein domain. The rearrangement of exons to form different combinations result in protein domain.
