Explain how cell signaling pathways in prokaryotes and eukaryotes demonstrate conservation of major features over time
svetoff [14.1K]

Cellular structures and lifestyles are much diversified. In spite of these differences, the same basic molecular mechanisms govern the lives of both prokaryotes and eukaryotes,<span> the general classes of proteins involved in signal transduction are conserved all over living cell. This is manifested through the re-used of protein receptors, protein kinases,<span> phosphoprotein phosphates, and ion channel receptors.</span></span>

The pmi for remains of a body enclosed in a plastic bag could best be estimated by
scoundrel [369]
The post mortem interval of a body enclosed in a plastic bag could be best estimated by the insects found in the body, in that case forensic science need to listen to what those little creatures have to say, insects could tell if the body has been moved from the crime scene, how long it´s been in an specific place, and how long it´s been since death until found, every group of insects can tell something different, from worms, arachnids to flyes, each one of them has a time to get into the body, so it could tell you for how long it´s been dead.

Explain what factors would cause a cell to stop at each of the 3 cell cycle checkpoints
Rudiy27

Answer and Explanation:

Cyclins and cyclin-dependent protein kinases (CDPKs, cell proteins) also function to control the cell cycle. A group of cyclins: the G1 cyclins, are synthesized during G1 phase and function to activate CDPKs which initiate DNA synthesis at the G1/S checkpoint. The cell fails to progress to S phase if there is no sufficient synthesis of G1 cyclins. After a cell passes through this point, the G1 cyclins are degraded, allowing for another group of cyclins: the M cyclins (mitotic cyclins) to be synthesized. M cyclins activate a second group of CDPKs which allow the cell to pass the G2/M control point and into mitosis.

In the G1/s check point, entrance into the S phase is blocked if the genome is damaged. In the G2/M check point, entrance into the M phase is halted if the DNA replication is incomplete. In the M phase, anaphase blocked if chromatids are not properly assembled.
