The prenatal development of the internal reproductive structures of the male requires the <span>secretion of androgens.</span>
The resulting mice will be induced with the changed gene either on or off. The offspring will have altered genes if both the alleles have the trait. This is a heritable change.
Explanation:
Making gene on or off is a process of gene regulation when one of the gene is methylated or histone modification to prevent access to transcription factors hence no expression of the protein. This process is called epigenetics.
The resulting progeny in mice will receive the allele of on or off the gene. Such genes with altered allele are also called as
The altered genes will be expressed in the resulting progeny of mice.
The epigenetic genes can be reverted with environmental effects in the offspring paramutable alleles. They are heritable.
In general, the term organelle is used for the small structures within a cell.
Answer:
How cloning works: In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed. ... This young animal is referred to as a clone.
Basics of cloning:
Isolation of target DNA fragments (often referred to as inserts)
Ligation of inserts into an appropriate cloning vector, creating recombinant molecules (e.g., plasmids)
Transformation of recombinant plasmids into bacteria or other suitable host for propagation.
Screening/selection of hosts containing the intended recombinant plasmid .
Explanation:
Answer:
Option A
Explanation:
In a circular economy, good/services/monetary object is in continuous usage up till its maximum value. The good/services/monetary object keep on moving from one service life (one user) to other service life (other user) as they are regenerated and recovered at the end of each service life.
In option A, thrift store has been used to its full extent in one service life and then it is donated (start of second service life)
Hence, option A is correct
