Answer:
50
Explanation:
egg cells and sperm cells contain half of the chromosomes of a regular cell in an organism, so the number of chromosomes in a heart cell must be double of the chromosomes in a egg cell.
Answer:
b. False
Explanation:
These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.
The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.
For a PCR reaction to be performed a solution with some components must be prepared. These components are:
- Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
- Forward and reverse primers (to customize the start of the enzyme reaction)
- DNA polymerase (Enzyme required for replication of desired DNA region.)
- DNA Template (the DNA to be copied)
- PCR-grade water
- Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
The part of the neuron that carries impulses away from the cell body is the axon. Think Axon, Away.
Answer:
There are two types of vesicle transport, endocytosis and exocytosis (illustrated in the Figure below). Both processes are active transport processes, requiring energy. Illustration of the two types of vesicle transport, exocytosis and endocytosis.
Explanation:
So in a simple explanation yes they require energy:)
In each cell, through a process of gene expression, DNA is transcripted into mRNA which are templates used to create different proteins resulting in different functions in your body.
