The 2 basic functions of meiosis are to

Maintain chromosome number through generations

Cause genetic variations by recombination.
stira [4]3 years ago

Answer:

The correct answers would be maintain chromosome number through generations  and cause genetic variations by recombination.

In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.

It helps in the formation of gametes in sexually reproducing organisms.

These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.

In absence of meiosis, the chromosomal number would have doubled after each generation.

In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.

During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.

Anatomy<br> Label each of the following structures or processes.
RSB [31]

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

<em>The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.</em>

The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.
