Each hemoglobin contains four iron-containing heme groups and four polypeptide chains. Four oxygen molecules can bind each Hb molecule.
True, four hemoglobin chains will contain one heme group, which will bind exactly one oxygen molecule. Since hemoglobin contains four globin chains with four heme groups, four oxygen molecules can bind to one hemoglobin molecule.
<h3>What is
hemoglobin ?</h3>
Blood-carrying protein hemoglobin (haemoglobin BrE) is derived from the Greek word haîma and the Latin term globus. (/hi-m-lo-bn, h-mo-/ abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein found in the tissues of some invertebrates as well as the red blood cells (erythrocytes) of practically all vertebrates (with the exception of the fish family Channichthyidae). The blood's hemoglobin transports oxygen from the respiratory system, including the lungs and gills, to the rest of the body (i.e. tissues). There, the oxygen is released, allowing aerobic respiration to take place and produce energy for an organism's metabolic processes. Every 100 mL of blood in a healthy person has 12 to 20 grams of hemoglobin.

Answer:
answer in my thought is A
Its either b or c. they both are right
DNA replication occurs in the nucleus. (The nucleus has a specific environment that ensures DNA is not degraded)
Transcription of genes to result in RNA occurs in the nucleus. RNA processing (e.g. the addition of a poly-A tail to each 3' end of mRNA) occurs in the nucleus as well.
Translation occurs in the cytoplasm.
Hope this helps! :)
The sequence of DNA carries the genetic information of an organism.
<h3>What is DNA?</h3>
DNA (Deoxyribonucleic Acid) is a molecule present in the nucleus of the cells of all living beings and that carries all the genetic information of an organism. It is formed by a double strand in the form of a spiral (double helix), composed of nucleotides.
DNA is made up of two chains of polynucleotides (strand), which are made up of several nucleotides. Nucleotides are joined together by bonds called phosphodiester (phosphate group linking two sugars of two nucleotides).
