Explanation:
new cells rather than growing bigger. Why is this ?
There are two main reasons why cells divide rather than continuing to grow larger and larger: ... If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Cell Division. Cell division is the process by which cellular material is divided between two new daughter cells.
Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions?
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? again The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
i belive this is just the introduction to the project but here
DNA polymerase is the enzyme that is responsible for adding correct nucleotide pairs to new and growing DNA strands. Mismatched base pair errors will occur if this enzymes is not able to function optimally. There are other system that work DNA polymerase, these are proof reading system and mismatch repair system. Less than optimum function of these system will lead to uncorrected mismatched base pairs.
It’s because unlike twins the regular siblings aren’t born on the same date or a couple minutes apart, but rather a couple years old or younger.
The relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.
<h3>What is sequence homo-logy?</h3>
In molecular biology, sequence homo-logy means the degree of similarity between sequences due to a common ancestor.
A sequence is a given fragment of a single DNA strand where nucleotides are arranged in a specific linear order.
Divergence or separation between lineages is directly proportional to the level of sequence homo-logy.
In conclusion, the relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.
