Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage.

Answer:
genes
Explanation:dna whatttt
Answer:
Each section of a chromosome that contains the code for the production of a particular protein is called a gene . Each chromosome is made from a single molecule of DNA, but when a cell is ready to divide, the DNA copies itself, then coils and condenses to form the chromosomes that we see in micrographs .

This woman is riding a bicycle down a hill at a constant speed and in a straight line. Which change will increase the speed of the bicycle?
A. An added force of 20 N to the side of the hill B. Added forces of 30 N up the hill and 20 N down the hill
C. Added forces of 30 N up the hill and 30 N down the hill
D. An added force of 20 N down the hill
Answers
An added force of 20 N down the hill will increase the speed of the bicycle, stronger gravity is applied to things with higher masses, hence option D is correct.
What condition if a bicycle down a hill at a constant speed?A force that unites things. You stay on the ground thanks to the Earth's gravity, which also causes things to fall. Everyone and everything is affected by gravity.
Gravity is the force that pulls the cyclist down toward the ground. Riding the bike ahead on a completely level road encounters very little resistance from the effects of gravity.
Cyclist gains speed even when they are not pedaling because the potential energy produced by a hill's height is converted into an equivalent increase in kinetic energy.
Therefore, an added force of 20 N down the hill is correct.

Answer:
I hope this helps
Explanation:
When a cell needs to make proteins, it looks for ribosomes. Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains. Ribosomes are special because they are found in both prokaryotes and eukaryotes.
Which statement best describes cancer cells?
A.cells that go through mitosis successfully
B.cells that continue to replicated even when not needed and does not stop
C.cells that move to G0,the resting phase
D.cells in hypotonic, solution to burst
Answers
Answer:
B!
Explanation:
Cancer is a essentially a mistake in a cell's DNA. This is very gradual, and takes a while. The immune system deals with most of them, but some slip out of reach and continue to mutate until they grow into tumors, or large pockets of cancer cells. Since their genetic code is very messed up at this point they have no limitations on growth.

Which option contains all of the other options listed?
gene

centromere
Answers
Answer:
The chromosome contains all of the other options listed.
Explanation:
In eukaryotes, the complete chromosome is composed of only one lineal and extremely long DNI molecule. DNA is intimately associated with two types of proteins: histones, which are structural proteins, and non-histone proteins that mediate different functions of DNA. DNI associated with histones is called chromatin. Histones are responsible for packaging the DNI molecule.
In the interphase, before cellular division, chromatin is in a diffuse, lax, uncondensed state. When cellular division is about to happen, chromatin begins to condensate, and the chromatin strand generates a copy or clon so both of the daughter cells can get the same genetic information. At the beginning of the prophase, DNI is condensed in a well-defined chromosome formed by two sister chromatids. In metaphase, two chromatids joined by a centromere form the typical chromosome.
So, one chromosome is composed of two sister chromatids condensated and joint by the centromere. It looks X-shaped.
Genes are located in chromosomes, specifically in the DNA strand.
