The scientists modified the genes that were turned on/off (expressed) in mice. What happened to the offspring of these mice?
daser333 [38]

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.

Which organelle is found in both eukaryotic cells and prokaryotic cells:
Ludmilka [50]

Answer:

c. Ribosomes

Explanation:

Ribosomes can be found in eukaryotic and prokaryotic cells.  In eukaryotes they are distributed by the cytoplasm, or trapped in the membranes of the endoplasmic reticulum. In prokaryotes they are found free in the cytoplasm.  In both cells, ribosomes intertwine into an RNA molecule and form polysomes.

Ribosomes are made up of two subunits, the two parts are made up of RNA molecules and proteins. This molecule has the main function of protein synthesis, that is, it is through it that aminoacids reconcile to produce proteins.
