The esr1 gene is ________ in cancerous breast tissue and the grb7 gene is ________ in cancerous breast tissue for ms. Cantu.
oksian1 [2.3K]

For Ms. Cantu, the GRB7 gene is not expressed in malignant breast tissue while the ESR1 gene is upregulated in such tissue.

Upregulated genes are shown by the colour red.

Down-regulated genes are shown by the colour green.

Non-differentially expressed genes are indicated by the colour yellow.

Absence of expression is shown by the colour black.

Hence from the table and colours ESR1 The GRB7 gene is not expressed, and the gene is upregulated.

10. What is the structure of chromatin and how does it affect gene regulation?
Airida [17]

Answer:

Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus. Chromatin structure plays a key role in regulating gene expression by allowing DNA accessibility to transcriptional machinery and transcription factors.

Hope this helps!

Answer:

Please read the explanation seeing the phylogeny attatched

Explanation:

a. is true. When you read a phylogeny you do it from tips to roots, tips that are close together come from the same node. All Anolis come from the same node, and Anolis genus and Leiocephalus genus share a common ancestor more distant than all Anolis.

b. If you see the tree, A. cristellatus and A. evermanni share a common ancestor, and the group that contains A. cristellatus and A. evermanni, share a common ancestor with A. occulatus. So A. cristellatus and A. evermanni are closely related among them than with A. occulatus

c and d. In the figure with colors, if lizards of the same body are closely related to each other than to lizards of different body types, your phylogeny should be colored by body shape. If not, your phylogeny should be colored by island (I use another group phylogeny to illustrate, but you should see the patterns on you phylogeny)
