If only one parent has sickle cell allele, then the child won’t get sickle cell disease. However, if both parents have sickle cell allele, then the probability of their child having the disease is pretty high
The two enzymes that are used during DNA replication is helicase
and polymerase. Each enzyme has distinct role that made it a vital part of the replication.
In the course of DNA replication, the initial stage is to unzip the double
helix structure of the DNA molecule by the enzyme helicase, which breaks the
hydrogen bonds that holds the complementary bases of DNA.
Moreover, the DNA polymerase has the ability to exactly copy a
DNA template. This enzyme binds to the leading strand and then adding a new
complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of
deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.

Answer:
A. FALSE
B. TRUE
C. FALSE
D. FALSE
Explanation:
A. DNA molecules consist of two strands of a helical chain of nucleotides, which are the monomer subunits of DNA.
B. Nucleotide subunits that make up a DNA strand are polar due to the presence of the phosphate group per subunit.
C. There are only four different nucleotides in a DNA strand. The nucleotides are different from each other based on the four nitrogen bases. These are adenine, thymine, cytosine, and guanine.
D. Hydrogen bonds are present between the nitrogen bases of nucleotides from anti-parallel DNA strands. Phosphodiester bonds, on the other hand are present between nucleotides of an individual DNA strand thus holding one DNA molecule together.
Answer: In the mitochondria.
Explanation: The enzymes of fatty acid break down are located in the mitochondrial matrix. Fatty acid break down occurs in the mitochondria in a process known as beta oxidation. Beta oxidation involves the break down of fatty acids to acetyl CoA. Beta oxidation involves the oxidative removal of successive two carbon units in the form of acetyl CoA .
Acetyl CoA produced enters into the citric acid cycle for the generation of ATP.
Answer is D because it’s dominant and is only given to 2/4
