The right answer is It produces male and female sex cells.

Meiosis is the process of double cell division allowing the formation of gametes, or sexual cells in eukaryotic organisms. It differs from mitosis, somatic cell division, which takes place only in a time. From a diploid mother cell, we obtain four haploid daughter cells with different genetic material.

In the above diagram of a plant cell, what is the function of structure 3?
kramer

Explanation:

B.  serves as the control center of the cell and contains the cell's genetic information

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wounucleuscarbohynd around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Further Explanation:

A cell's structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

  • may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
  • separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins

Which of the chains of amino acids corresponds to the nucleotide sequence aauggcuac
maxonik [38]
The sequence AAU GGC UAC is composed of three codons each of which codes for a different amino acid. AAU codes for the amino acid called threonine. GGC codes for the amino acid called glycine UAC codes for the amino acid called tyrosine. So the chain will read  threonine-glycine-tyrosine. There are 64 possible 3 - letter combinations of DNA coding units A, C, G and T. Of these, there are three stop or non- sense codons that do not code for any amino acid, while the remaining 61 code for different amino acids.
