Answer: operon
Explanation:
An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule, which therefore encodes multiple proteins (Fig. 16.11). Such polycistronic mRNA is typically found in prokaryotes.
Answer:
Mitochondria is known as the powerhouse of the cell as it provides energy to the cell for performing different functions.
If a toxin causes pore in the inner membrane of the mitochondria and increases the permeability of the mitochondrial membranes. The permeability of mitochondrial membranes leads to mitochondrial swelling and causes cell death through necrosis and apoptosis.
Root hairs are important to a plant because they increase the surface area for absorption. i really hope this helps.
Answer:
It concludes that the man is not the real father of the girl child.
Explanation:
Sex-linked or the X linked characters are the traits that inherited in a change or mutation in X chromosomes that cause the phenotype change in the male, which are homozygous for the gene as only possess one X chromosome and one Y chromosome, and Females if they are homozygous for the gene.
In the question, Man has a normal color vision (XrY) that means he has no mutated allele of color blindness. female has color blindness so that means she is a homozygous chromosome for the gene. Cross between these two results in 50% carrier daughters (XrXR) and 50% color blindness son (XRY). It means there is no chance for the color blind daughter.
Thus, the correct answer would be the man is not the real father of the girl child.
