Answer:
The inducer will combines with the repressor and inactivates the pathway.
Explanation:
Inducer is a term in Molecular Biology, which represent a molecule or substance that has the capability to activate the transcription of a gene, where by it joins with and then inactivates a genetic repressor.
In other words, the inducer binds with the repressor in order to prevent the RNA polymerase to combine to the DNA, and chemically produce mRNA, this is done by repressor proteins combining with the DNA strand.
Inducer specifically makes repressor to change shapes, which will make it not combine with the DNA, and therefore, allow formation of transcription, such that expression of gene will eventually occur.
Answer:
This question lacks options, the options are:
A) FF and ff
B) FF and Ff
C) Ff and Ff
D) Ff and ff
The answer is D (Ff and ff for parent 1 and 2 respectively)
Explanation:
This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.
According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.
To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).
In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.
Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).
Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.
Answer: metagenomics
Explanation:
Metagenomics is the study of the collective genome of the microorganisms obtain from the environment. The study can provide details of the microbial diversity and ecology for a particular environment. It allows the identification of the specific microbial species from the mixture of genomic samples. The metagenomics is useful in solving the problems related to other fields such as medicine, agriculture, engineering and ecology.
Hello!
Vesicles is a transport material within the cell.
Answer:
An important way of making ATP without oxygen is called fermentation. It involves glycolysis, but not the other two stages of aerobic respiration. Many bacteria and yeasts carry out fermentation. ... This occurs when muscle cells cannot get oxygen fast enough to meet their energy needs through aerobic respiration.
