As part of your independent study in field biology, you are sent to a small, inland sea. In one of your samples, you discover a

small eel-like creature. It has a stiff, rod-shaped structure running the length of its dorsal side, with a line of nervous tissue running along with it. You would begin the process of classifying this organism by placing it in phylum:

<h2>Phylum Chordata</h2>

Explanation:

The organism which have a well defined neural chord or notochord running throughtout the length of there dorsal surface atleast once in their life time are classified as chordates.

Since the organism we found is a eel like with a stiff rod shaped structure running the length of its dorsal side, with a line of nervous tissue running tissue which represents a notochord, classification should begin by placing it in Phylum chordata.

Long ears have to be dominant:

If this IS true then these would be your 'parents':

L = long ears
l = curly ears

LL x ll

If you cross the homozygous recessive curly eared rabbit (ll) with homozygous dominant long eared rabbit (LL) you would get 100% Ll - all would look long eared.

1.) You are studying P120, a protein of 120 KDa that is continuously synthesized in eukaryotic cells. Its cellular concentration
irina1246 [14]

Answer:

1. P120 is degraded in the 26S proteasome

2. The 26S proteasome has a major role in protein degradation and is critical for protein homeostasis

3. Cell cycle and DNA replication are cellular processes regulated by the Ras and NFkB pathways

Explanation:

The proliferation-associated nucleolar protein (p120) is a protein known to be expressed during the interphase of the cell cycle, specifically in G1 and early S phase, where any problem with DNA replication trigger a checkpoint, i.e., a molecular cascade of signaling events that suspend DNA replication until the problem is resolved. In mammalian cells, the 26S proteasome is responsible for catalyzing protein degradation of about 80% (or even more) of their proteins. The 26S proteasome acts to degrade rapidly misfolded and regulatory proteins involved in the cell cycle, thereby having a major role in protein homeostasis and in the control of cellular processes. It is for that reason that inhibitors that block 26S proteasome function have shown to be useful as therapeutic agents in diseases associated with the failure of protein degradation mechanisms (e.g., multiple myeloma). The NF-κB are highly conserved transcription factors capable of regulating different cellular processes including, among others, cellular growth, inflammatory responses and apoptosis. Moreover, the MAPK/ERK pathway is able to transduce different signals received on the cell surface to the nucleus. The MAPK/ERK pathway is activated when a singling molecule binds to a cell receptor which triggers a signaling cascade that ends when a transcription factor induces the expression of target genes, ultimately producing a response in the cell (for example, the progression through the cell cycle).
