Splicing, adding of the cap and tail, and the exit of the mRNA from the nucleus.
Answer:
harmful effect and no effect
Explanation:
No effect: most mutated genes destroy themselves before it gets to far
Harmful effect: an example of harmful effects would be down-syndrome (where you have 3 21-chromosomes and you are only supposed to have 2)
Answer:
b) Hydrogen
Explanation:
The figure shows the hydrogen bonding of two <u>H2O molecules</u>. The red atom is Oxygen which is δ−, and the white atom is Hydrogen which is δ+, this is determined by their <u>electronegativity</u>. H2O molecules can form hydrogen bonding when the Hydrogen atom bonds through hydrogen bonding to the oxygen atom and vice versa.
This type of bond is an <u>intermolecular bond</u>
Answer:
By Controlling transcription
Explanation:
Prokaryotic cells regulate their gene expression by controlling the amount of transcription. This is the only way of regulating the gene expression.
Unlike the prokaryotic cell, in eukaryotic cell, different compartments were formed for carrying out different cellular processes. Later on, transcription and translation were physically separated and were carried out in two different cellular compartments
Answer:
Explanation:
There are two main types of succession:
Primary succession. begins with bare rock exposed by geologic activity. example sere: rock -> lichen -> moss -> grass -> shrub -> trees -> oak hickory forest.
Secondary succession. begins on soil from which previous community has been removed (by fire, agriculture, etc.)
