Alternative splicing is the process of gene expression. It results in a single gene being able to produce multiple functional proteins. mRNA splicing includes certain exons and excludes others. This produces different mRNA strands with different base sequences, which then translates to different polypeptide chains with different codon sequences. Different polypeptide chains will then go through processing to become different proteins.
Hope this helps! :)
Answer: False
Explanation:
It's the opposite! Hot, less material rises while the cold, more dense material sinks
Answer:
Disruptive Selection
Explanation:
When the extreme values of trait favor over the intermediate values of traits then such form of selection is known as disruptive selection.
Here, the extreme trait values are both beige-coated and brown-coated goats while white-coated goats have intermediate traits.
Answer:
Volume is the amount of space occupied by a sample of matter. The volume of a regular object can be calculated by multiplying its length by its width by its height. Since each of those is a linear measurement, we say that units of volume are derived from units of length.
Explanation:
Answer;
Primitive streak.
At the onset of the embryonic period, the primitive streak appears. It will eventually become the neural tube.
Explanation;
The primitive streak is a transient structure which forms on day 15 of human development.
It marks the start of gastrulation; the process in which the inner cell mass in converted into the trilaminar embryonic disc.
It originates from the anterior epiblast.
