Trisomy 21 (nondisjunction) Down syndrome is usually caused by an error in cell division called "nondisjunction." Nondisjunction results in an embryo with three copies of chromosome 21 instead of the usual two. Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separate.
Oxygen is produced in the light stage of photosynthesis at Photosystem 2 and results from the splitting of water. Chlorophyll does not absorb green light so in green light there will be less water split and so less oxygen is produced.so thats how we know the reason why a leaf is the color that it is. basically it is because of chlorophyll.
Hope this helps.
A common cold is caused by a virus, not bacteria
Answer:
The examples of Golgi apparatus are stated below: Explanation: The Golgi apparatus is present in eukaryotic cells where many substances such as proteins are secreted. In plants, this organelle is referred to as dictyosome. In flagellate protozoa, it is called parabasal body. The collective term for all the Golgi apparatus in the cell is Golgi complex.
Explanation:
Answer:
Translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. The process starts where the mRNAs (messenger RNA) copies the DNA and sends this message to the ribosome. In the ribosome for each triplet of nucleotide an amino acid is bond to the growing chain of amino acid that will eventually form a protein.
You can look up for the translation for the genetic on the internet. Which tells you which triplet codifies for an specific amino acid.
If the code reads. CGC GCG CGC GCG etc.
The result would be an a peptide/protein containing alternating arginines and alanines, because CGC codifies for Arginine and GCG codifies for alanine.
