Answer:

Mutations during meiosis can often lead to disorders, diseases, etc.

Explanation:Let's say that one of the tetrads formed in the first steps of meiosis It doesn't separate and goes on. When making gametes, some will contain the necessary amount of chromosomes while others will not

The result of mutation during meiosis is that the offspring of the organism will have a mutation.

Meiosis is a proces by which cells divide in order to produce four other cells, each with half the full complement of DNA. Meiosis aims to produce gametes (eggs and sperm cells).  Errors may take place during meiosis giving way to gametes with an extra or missing chromosome.

During the process of meiosis, chromosomes are replicated once in S phase (just like mitosis) into sister chromatids, but the cell divides twice.

According to the context, fungi is an organism that digests its food externally before absorbing it and it cannot move.

<h3>What are fungi?</h3>

They are living beings belonging to the fungi kingdom: molds, yeasts and mushrooms.

These lack mobility and senses, like plants, and they consume available organic matter (heterotrophic nutrition).

Therefore, we can conclude that according to the context, fungi is an organism that digests its food externally before absorbing it and it cannot move.

Assuming DNA is replicated correctly (so there are no mutations),
gavmur [86]

Answer:

None of the choices would lead to all identical gametes.

Explanation:

Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.

The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.

Classify each description as true of introns only, exons only, or both.A-present in eukaryotic genomesB-generally absent from ba
maxonik [38]

The right answers are:

A-present in eukaryotic genomes ==> Both exons and introns

B-generally absent from bacterial genomes ==> Introns

C-part of the final mRNA strand ==> Exons

D-code for an amino acid sequence ==> Exons

E-removed from initial mRNA strand prior to translation ==> Introns

F-present in the DNA used as the template for transcription ==> Both exons and introns

In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.

Not just a woman, but any astronaut:
