Answer:

allele

Explanation:

An allele can be defined as a variant of a gene localized at the same locus or chromosome position. These gene variants may encode the same protein (when different alleles encode the same protein sequence) or different protein variants (when nucleotidic differences encode distinct protein sequences). It is important to note that the diploid organisms (like humans) have two alleles for each gene, which are localized on homologous chromosomes.

Earth is special because it is an ocean planet. Water covers 70 percent of Earth's surface. Earth's atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe.There are multiple reasons for earth to be a special planet. Reasons are as follows

1.Earth is the only planet known where intelligent life exist.

2.It lies in the circumstellar habitable zone (CHZ). CHZ is defined in the image given below.

3. Earth has a unique magnetic field which protects the earth from the harmful solar winds. These solar winds played a role in transforming venus into hell.

4. Earth has Van Allen radiation belts which protects it from cosmic rays.

5. Our large neighbour Jupiter protects is from many comets and asteroids that come from the keiper belt and Oort cloud.

6. Earth's atmosphere is favorable to support life on earth. This atmosphere consists of different gases in adequate amount. If the percentage of gases would differ then life on earth may face serious consequences.

7. Tectonic plates of earth differentiates it from most other planets.

8. Earth has a solid crust unlike the gaseous planets.

9. Earth has been gifted with a medium sized star which release solar winds and protect us from the harmful radiation of outer space.

Methylation of EZH2 by PRMT1 regulates its stability and promotes breast cancer metastasis. Cell Death Differ. 2020,
vovangra [49]

Yes, it is true that Methylation of EZH2 by PRMT1 regulates its stability and promotes breast cancer metastasis.

Enhancer of zeste homolog 2 (EZH2), a key histone methyltransferase and EMT inducer, is overexpressed in diverse carcinomas, including breast cancer.

However, the molecular mechanisms of EZH2 dysregulation in cancers are still largely unknown. Here, we discover that EZH2 is asymmetrically dimethylated at R342 (meR342-EZH2) by PRMT1.

meR342-EZH2 was found to inhibit the CDK1-mediated phosphorylation of EZH2 at T345 and T487, thereby attenuating EZH2 ubiquitylation mediated by the E3 ligase TRAF6.

We also demonstrate that meR342-EZH2 resulted in a decrease in EZH2 target gene expression, but an increase in breast cancer cell EMT, invasion and metastasis.

Moreover, we confirm the positive correlations among PRMT1, meR342-EZH2 and EZH2 expression in the breast cancer tissues. Finally, we report that high expression levels of meR342-EZH2 predict a poor clinical outcome in breast cancer patients.

Our findings may provide a novel diagnostic target and promising therapeutic target for breast cancer metastasis.

The lac operon in E.coli regulates genes that code for enzymes required for breakdown of lactose. The lac operon is____ operon t
user100 [1]

Ans.

Lac (lactose) operon in a type of bacterial operon, which shows a cluster of genes that are regulated by a single promoter. It is composed of an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for the transport and breakdown of lactose.

The lac operon is an inducible operon as it gets activated in the presence of lactose and expressed its functional genes in the form of proteins (or enzymes) for lactose metabolism.  

Thus, the correct answer to be fill in first blank is 'inducible' and in second blank is 'lactose.'
