I’m pretty sure its gneiss but I might be wrong. Let me know and have a good rest of your day!
Carbon dioxide and water react to produce glucose and oxygen. Chlorophyll absorbs light and convert it into chemical energy.
Answer:
1) A, C and D
2) D
Explanation:
The normal hemoglobin is made up of heme and globin. The protein, globin is in turn made up of four polypeptide chains which include two alpha and two beta chains.
The gene gene responsible for the creation of the beta globin chain is located on the short arm of chromosome eleven. It is called the HBB gene. Many mutations occur on the HBB gene and a mutation on this gene produces abnormal hemoglobin like HBS, hbc, and hbe. HBs causes sickle cell anemia.
In sickle cell anemia, there is an alteration of the genetic code, leading to the substitution of a single amino acid where glutamic acid is replaced by valine in the sixth position of the beta chain.
In the mRNA, the change converts a glutamic acid codon(GAG or GAA) to a valine codon(GUA, GUC, GUU or GUG).
Sickle cell anemia is caused by a transversion that leads to a missense mutation.
Answer: The structures that are found in both eukaryotic and prokaryotic cell are-
ribosomes, DNA, cytoplasm.
Ribosomes are biomolecular complex, composed of RNA and protein and act as the site for protein synthesis in all the cells of the living organisms.
DNA (deoxyribonucleic acid) is considered as the genetic material of all life forms. It possesses the genetic instruction in the form of nucleotide sequences.
Cytoplasm is the fluid compartment of all the cells (where all the essential biochemical reactions take place) that is surrounded by cell membrane.
Thus, ribosomes, DNA, cytoplasm is the right answer.
1. amino group
2. hydrogen
3. carboxyl group
4. R group
