Nuclear fusion takes place at the core of the sun
1) Mutations are caused by changes in nucleotide bases. these altered base formed different amino acid depending upon nucleotide base sequence that code specific amino acid. ... even though some mutations, can have a more effect on amino acid coding, which can affect what kind of proteins are produced.

Pulmonary vein. It enters your pulmonary vein and then enters your left atrium.

Answer:
The correct answer is the letter D. decreasing the moisture content of the air and increasing temperature
Explanation:
Fog is the result of air humidity, or water vapor in the atmosphere. The mist that forms in the morning is the result of water that changes from a gaseous to a liquid state. It is characterized by a cluster of water droplets, which give rise to a type of cloud that is very close to the Earth's surface arising from the cooling of the air during the night. Thus, it is formed by the suspension of water droplets in an air layer close to the ground. Thus, fog can be considered a cloud that comes into contact with the ground.
Answer:
With the invention of the PCR technique , DNA profiling took huge strides forward in both discriminating power and the ability to recover information from very small or degraded starting samples.
The process of PCR mimics the biological process of DNA replication but confines it to specific DNA sequences of interest.
In PCR process , the DNA sample is denatured into separate individual polynucleotide strands through heating. Two oligonucleotide DNA primers are used to hybridise to two corresponding nearby sites on opposite DNA strands. Thus two new copies of the sequences of interest are generated.
Repeated denaturation , hybridisation and extension in this fashion produce an exponentially growing number of copies of the DNA of interest.
Quantitative PCR methods enable automated , precise and high - throughput measurements.
