DNA is copied because it cannot fit through the nuclear membrane and travel down to the ribosome.
So it is transcribed (translated) to messenger RNA (mRNA). The mRNA can fit through the nuclear membrane and travel down to the ribosome where proteins can be made.
This is why we cannot send the entire DNA molecule itself, it is simply too big to fit. This is why mRNA is extremely important for amino acid production.
<span>"Water stress" is when the demand of water exceeds its supplies. Factors that increase water stress include increased population, pollution of existing water sources and periods of drought. Ways to combat water stress may be proper distribution of water, establishment of sanitation facilities and prevention of pollution of water sources.</span>
The electron transport chain (ETC) is the final step of cellular respiration and takes place in the mitochondrion.
- The final step in cellular respiration is the electron transport chain. This is sometimes abbreviated as ETC. ETC needs oxygen, which means aerobic process. It occurs at the edges of the inner lining of mitochondria. These handles are called cristae.
The crust must have continental (granitic) plate and oceanic (basaltic) plate to cause both explosive (granitic magma) and non-explosive (basaltic magma) eruptions.
Answer:
A cross between two pure breeding tall (TT) and dwarf (tt) parent plants produce uniform F
Explanation:
generation of dominant individuals (Tt).
According to the law of dominance, a trait is represented by two contrasting factors of a gene in a heterozygous individual; the allele/factor that can express itself in a heterozygous individual is called as a dominant trait. Another factor whose effect is masked by the presence of a dominant factor is called a recessive factor. The recessive factor, t, is present in F
hybrids but its expression is masked by the factor for a dominant trait, T.
