After addition of serum to G0-arrested mammalian cells, two classes of genes are expressed: early-response genes and delayed-response genes. Explain why expression of delayed-response genes is blocked by inhibitors of protein synthesis but expression of early-response genes is not.

In mammalian cells, genes that are expressed in a particular
cell are reported to undergo replication during the first half of S
phase, and genes not expressed in that cell are replicated in the
latter half of S phase.
Briefly describe an experiment that could lead to this
conclusion. You might consider approaches that involve
5-bromouracil incorporation.
Rank from the first step to the last step. To rank items as
equivalent, overlap them.

At 5 am your alarm goes off. Genes are expressed in response to that stimulus and you throw the clock out the window. How are several different genes expressed simultaneously? a) What are promoters? b) How do promoters control gene expression? c) What molecules are involved? d) Which moleculasare cis factors? Which moleculesare trans factors? e) What would be common about the promoters for the different genes above?? tRNA and rRNA genes are involved in protein synthesis and yet do...
In female mice, both the glucocorticoid (cortisol) receptor and the estrogen receptor are expressed in liver cells (hepatocytes). The control element to which the glucocorticoid receptor binds is a short-strip of DNA that can accommodate the binding of the glucocorticoid receptor dimer. This control element is called a glucocorticoid response element (GRE). It is located1000 bp downstream from the poly-A site for the PEPCK gene. When this gene is activated by cortisol, it helps the hepatocyte to release glucose into...
explain 1 or 2 molecular details in how epigenetics may allow
melanoma cells to outsmart BRAF inhibitors

Seope: This science commentary claims that epigeneties plays a role in cancer cells becoming therapy-resistant. The language used is generalized for the non-scientist and does not include any molecular details, such as methylation of a specific nucleotide in an allele or modification of a specific histone tail amino acid. Your task (individually or in a group of...
1.In early March, it was reported that two main strains of SARS-CoV-2 had been identified, termed S and L, with the S type being the less virulent ancestral form representing about 30% of prevalence and the more virulent L type having descended from the S type and representing about 70% of prevalence. However, the prevalence of the more virulent L type seems to have decreased after early January, and it is thought that this resulted from human intervention against this...
QUESTION 1 Although SARS-CoV-2 is currently a global health threat, how might we turn it into a tool for biotechnology? a. It could possibly be turned into a viral vector against lung cancers b. Its promoters might be used to express genes in lung cells c. Its surface proteins could be used for new epitope tags d. All of the above QUESTION 2 Which of the following are applications of molecular assembly described in this course? a. It can be...

Immunology Question
May you check my answers for 2a and 2b and see if: the
information is being accurately presented, there is no unneeded
information, and most importantly it is answering the question? I
added more information to strengthen my answer so hopefully, it is
better this time around. Thank you in advance!

1. According to the paper, what does lactate dehydrogenase
(LDH) do and what does it allow to happen within the myofiber? (5
points)
2. According to the paper, what is the major disadvantage of
relying on glycolysis during high-intensity exercise? (5
points)
3. Using Figure 1 in the paper, briefly describe the different
sources of ATP production at 50% versus 90% AND explain whether you
believe this depiction of ATP production applies to a Type IIX
myofiber in a human....
