A gene has the base sequence TAC CG. Give an example of a point mutation on this gene.
Norma-Jean [14]

Answer: An example of point mutation on the gene is TGC CG.

Explanation: Mutation is a permanent alteration in the nucleotide sequence of a DNA. Point mutation is a type of mutation in which there is a change in only one nucleotide molecule in a DNA sequence. A point mutation can occur at any point in the nucleotide sequence of a DNA and can be as a result of replacement of one nucleotide molecule by another. For example, in the the sequence TAC CG, any of the nucleotides can be replaced by another nucleotide such as in TGC CG, Adenine is replaced by Guanine.

Which of these is an environmental effect of deforesation?
Nata [24]
"Deforestation is the permanent destruction of forests in order to make the land available for other uses. An estimated 18 million acres (7.3 million hectares) of forest, which is roughly the size of the country of Panama, are lost each year, according to the United Nations' Food and Agriculture Organization (FAO)"
The conversion of forests into agricultural plantations is a major cause of deforestation. The increase in global demand for commodities, such as palm oil and soybeans, are driving industrial-scale producers to clear forests at an alarming rate. Indonesia, the largest producer of palm oil, was named the “Fastest Forest Destroyer,” in the 2008 Guinness World Records. Even when efforts are made to replenish barren plantations, the depleted soil is not able to produce the same biodiversity it once was."
Forest clearing for livestock ranching is another contributor of deforestation. Since 1990, Brazil, a top exporter of beef, has lost an area of forest that is three-fourths the size of Texas. A strong global demand for beef, supported by governments such as in Brazil, is expanding this kind of deforestation.

Answer:

The correct answer is c it inhibits the movement of small subunit relative to the large subunit.

Explanation:

According to the question the the poison that is added in vitro translation mixture containing mRNA molecules specific sequence result in formation of Met-lys dipeptide that remains attached to the ribosome.
