Answer:   Differences in mRNA splicing.

Explanation:

The exon is the region of a gene that is not separated during the cutting and splicing process and thus remains in the mature messenger RNA. In genes encoding a protein, it is the exons which contain the information to produce the protein encoded in the gene. In these cases, each exon encodes a specific portion of the complete protein, so that the set of exons forms the coding region of the gene. In eukaryotes, the exons of a gene are separated by long regions of DNA (called introns) which do not code.

RNA splicing is a post-transcriptional process of maturing RNA from which certain sequential fragments are removed. This process is very common in eukaryotes, and can occur in any type of RNA, although it is more common in mRNA. It consists of removing the introns from the primary transcript and then binding the exons. Particularly, <u>alternative RNA splicing takes place when one gene can produce different proteins as a result of what segments are considered as introns and exons</u>. When different segments are considered exons, the result is a great diversity of mature transcripts which produce different proteins.

<u>So, gene splicing is a post-transcriptional modification in which a gene can code for many proteins, which makes it an important source of protein diversity.</u>

To measure the population of lake trout in a 250-hectare lake, 400 individual trout were netted and marked with a fin clip, then
kenny6666 [7]

Answer:

Estimated size is 1600

Explanation:

Given data:

Size of lake is 250 hectares

Total number of trout who netted is 400

Total number of trout in next week is 200

Total number of trout having fin clip 50

estimation population size is estimated by mark rupture as follow

Estimated population size = \frac{(marked\ initally \times total\ recaptured)}{mark\ recaptured}

Estimated size= \frac{400\times 200)}{50}

Estimated size is 1600

Seeds are a derived character of the spermatophytes. All of the plants in this clade reproduce using seeds. However, embryo form
Natasha2012 [34]

Embryophyta is a clade within the Phragmoplastophyta, a larger clade that also includes several green algae groups. Embryophytes are the plants growing on land which include hornworts, liverworts, gymnosperms, flowering plants etc while green algae mostly thrive in aquatic environment.

The conduction of water requires vascular tissue called xylem. In green algae, it is not necessary to have water conducting tissue as the entire body is in contact with water. However in embryophytes, having a vascular tissue is an adaptation that ensures to provide water to the higher parts of the plant which is not directly in contact with the soil.

Dovator [93]

Answer:

The answer is Make reclamation required after mining operations have ended

How are mitosis and meiosis similar apex?
xeze [42]
1. Similarities:they are both processes of cell division by which cells reproduce.
They share several steps of the process(prophase, metaphase, anaphase e telophase, cytokinesis) but meiosis has another division also with those same steps.
In both cases the cell duplicates its DNA by pulling it apart into two sets, place the sets on each end of the cell, and then divide down the middle.
Both produce new cells based on their parent cells' genes.
