People with two copies of the sickle cell gene have the disease. People who carry only one copy of the sickle cell gene do not have the disease, but may pass the gene on to their children. Abnormal hemoglobin, called hemoglobin S, causes sickle cell disease (SCD). The problem in hemoglobin S is caused by a small defect in the gene that directs the production of the beta globin part of hemoglobin. This small defect in the beta globin gene causes a problem in the beta globin part of hemoglobin, changing the way that hemoglobin works.
Answer:
Amino acids.
Explanation:
DNA is the genetic material of all the organisms except some viruses. DNA has the ability to replicate and produce daughter DNA cells by the process of replication.
DNA is made of polymers of nucleotides. DNA consists of nitrogenous base, in which adenine is linked with thymine, cytosine with guanine thriugh hydrogen bonding ,shows complementary base pairing. Pentose deoxyribose sugar and phosphate group. The DNA molecules are linked together through phosphodiester bonds. Amino acids is present in protein.
Thus, the answer is option (4).
Answer:
A) hybridization; morphospecies
Explanation:
The biological species concept is the concept which can define a species as an individual of a large population which can interbreed and produce an offspring in a population. The concept was given by Ernst Mayr.
Morphospecies refers to the species which can be characterised by the differences in their morphological features like in the Oak, willows and the dandelions.
The biological species concept is not valid or complicated in the case of the morphospecies like in the Oak, willows and the dandelions as the individuals of these three population can exchange their genes through the process of hybridization.
Thus, Option-A is the correct answer.
Vasospasm is a protecting reaction at some stage in the lively bleeding technique; it does not motive hydrocephalus. The Broca middle is not directly affected; even if it were, there may be no courting to the improvement of hydrocephalus. The production of cerebrospinal fluid isn't elevated in this situation; elevated production may additionally result when there's a tumor of the choroid plexus. The patron wishes the Physiological adaptation with the Cognitive stage Comprehension
