MRNA because the DNA gets carried
Plastids. Plant plastids are a group of closely related membrane-bound organelles that carry out many functions. They are responsible for photosynthesis, for storage of products such as starch, and for the synthesis of many types of molecules that are needed as cellular building blocks.
Answer:
The result of non-disjunction of chromosomes during meiosis, producing three copies of the chromosome in the embryos -instead of two- is called trisomy.
Explanation:
With reference to genetics, a cell is diploid because it has an even number of chromosomes, distributed in pairs - each of which is contributed by a parent - and responds to the formula 2n.
In trisomy, non-disjunction during meiosis of the homologous chromosomes causes an overloadin the corresponding gamete, which during fertilization will originate an embryo whose formula is 2n+1.
Trisomias are considered mutations, which can physically and functionally affect an individual, or even make an embryo not viable. <u>This defect can occur in both autosomes and sex chromosomes</u>.
A very common example of this mutation corresponds to the trisomy of chromosm 21, known as Down syndrome.
