When blood is in the lungs,
where oxygen is plentiful, oxygen easily binds to the first subunit and then quickly fills up the remaining ones. Then, as blood circulates through the body, the oxygen level drops while that of carbon dioxide increases. In this environment, hemoglobin releases its bound oxygen.
Answer: number 1
Explanation: that is when we could first sustain life because that is when we gained atmosphere and when we could hold carbon and oxogen
Answer:
The correct answer is 3 prime OH.
Explanation:
The joining of nucleotides takes place by a condensation reaction, which discharges a small, stable molecule. Unlike carbohydrates, proteins, and lipids, the molecules, which is discharged is not water, however, a pyrophosphate, that is, two phosphate groups combined together.
In the polymerization of DNA, a phosphodiester bond is formed between a free 5 prime phosphate group at one terminal and a free 3 prime hydroxyl group at the other end. The naming of these sequences is done from 5 prime to 3 prime.
Answer:
You can use the quantitative Reverse Transcription Polymerase Chain Reaction PCR (RT-qPCR) method in order to analyze the Oct4 mRNA level.
Explanation:
RT-PCR is the gold standard technique to analyze the expression levels of one particular messenger RNA (mRNA) molecule. In this technique, the total RNA is firstly extracted and transcribed into complementary DNA (cDNA). Subsequently, the gene sequence of interest is then amplified in a standard PCR technique that uses as control one or more genes in order to measure the relative expression levels of the target mRNA, in this case, for example, the Oct4 mRNA.
