The solution to GATE-BT-2017 // Q52

A DNA strand of 25 nm wraps diametrically around the circumference of a spherical histone-octamer once. The radius of the histone-octamer = ____

[Use pi = 3.14]

ANSWER:

Given: 3.90 - 4.10

Answer calculated: 3.95 nm

Steps:

1. 25 nm wraps once = it covers the perimeter of a 'circle that coincides with the sphere's diameter'

Thus, 25 nm = perimeter = 2r(pi) or pi x D,

2. Perimeter is pi x D = 25

Therefore,

    D = 25 / 3.14

    D = 7.9 nm

3. Find the radius from D like a school child :)

because D = 2R

Therefore, R = D/2 = 7.9 nm / 2 = 3.95 nm

R = 3.95 nm.

My answer matches with the answer key, so I think this does well to the question.

If I am wrong, do let me know in the comments below.

You can also let me know what other GATE BT / XL or CSIR - LS you'd like to see me solve!

Byee.

Stop, please. Stay.

Stay. I want them to stay. If even its for a little while longer, just a moment longer maybe, but I want them to stay. I do want them to stay forever in my life but everyone comes and everyone goes.

I guess its because everyone has a time to make an entry into our lives and the time comes for them to leave, they must do so.

It breaks me, most of the times.

Today, my sister woke up before me and made sure I get ready for office. She wanted me to leave a little later because I used to leave 15 minutes prior to my actual departure time, and I did leave today 15 minutes later than my usual time giving me the exact amount of time needed for mg travel to my new office.

I am seated on my bus, on my way to work as I type this in my word doc I have on my phone and remembered that moment in time. How funny it was that my sister wanted me to leave late and apparently things happened such that I did leave a little later than when I was supposed to.

When I was a child (like child kinda child, not adult-child; i was literally 10 years old or something) I used to sit on the floor with my crossed legs capturing my Dads’ legs telling him to not go to office. I was a child then, but somewhere I was afraid too I think. People whom I love, leave. Always.

And it hurts, and I want that to stop, but it ain’t gonna stop soon.

I just want them to stay, even if its for a little while longer.. I do want them to stay. If I could I’d probably hide them away from the mean world that is out there to get them.

I guess I am being a little selfish huh? Or maybe if you look at it from my lens you’d just understand that I am looking for ways to not be alone again to not be left out again, to be included in fun activities normal people do and pretend that I love staying at home while the wanderlusty version of me wants to dress up for dates or gear up for a hike or try a new restaurant. 

I have become much a Homebody whilst no one knows how much I yearn to be around with people, doing fun things, getting to know each other and their thoughts and their perspectives on things that matter like Life, After Life, Space, Evolution, Advancements in tech and so on and so forth.

Maybe I just wanna get rid of this lonely feeling I feel once in a while.

Musings from Nature #1

The winter cold mornings wake her up

With a cold whiff of breeze that grazes her cheek

And so he wakes up to sight her

In all her glory, her morning bed head, he laughs at

A giggle owning to the marvelous wonder that she is

Maybe the secrets to the universe are held in her coffee brown eyes, oh look, she rubs them with her tiny human hands...

Her hair falls at her back, wavy yet messy... the universe inspired to make waterfalls that are smooth yet turbulent

Her pot of milk boils, coffee is being made and she wakes up with a new life from the first sip of her joe

The sun tries to find her in places where shadows lie.

She hides away from the light, hiding and seeking the Roshini he's giving.

Oh! It's time for her to go out now... maybe he can find her then?

He seeks her amidst the scintilating pores of leaves that are natures pin hole camera and wonders... is she wearing black to take in all of me?

Well, then why does she cover her face with a Bandini print stole?

Stupid stole, cannot see her face! But I can still see her eyes. Ah, those coffee brown eyes... look at that, the audacity to cover them beautiful ambers with spectacles.

Alas, its not just me but Dharthi, Bhoomi, Akash and Vanam dont get to see her occulus. Her windows to her soul.

She walks in a pace to her bus stand... and lo, she took her ticket, she boards her bus, talks to her Ma and.. and! Hey!! She saw mee! Im elated beyond bounds.

She boards her bus and looks out for me, am I... am I shy? I do want to hide behind the clouds... she seeks me in ecstasy to drive her spirits. I admire her soul.

Hi there. I love you, here's a ray of sunshine for you. Go live your day beautiful!

Be my wife and I'll be yours

 A lady, in India, as soon as she is 18, her parents have reached a milestone - It's finally time!!

No, not for her to go to college and graduate with an education that can uplift the family and the society - no, no - It's finally time for her to get married and so parents of the lady; search for a Groom. "A suitable boy".

Dreams crushed, Feelings unresolved, made to walk a path she never even thought of in her daydreams or night tales or wishes when a shooting star passes by...

A suitable boy huh...?

Who is the ideal suitable boy? Someone like Ramachandra Dasharat? Someone like Krishna Vasudev? Someone like Majnu? Someone like Romeo? Someone like Ranjha?

Or someone, like  Shiva?

Someone who believes in women and equality.

Someone who showed the world an example of treating their wives just right.

Gauri was a homemaker, and she made Shiva, a wanderer, a reluctant man, into a family man - for someone who preached on unattachment all his life and to settle down with family and kids - I admire the irony.

Marriage does things to people huh?

He was worth the wait to Parvathy and settling down with Shakthi was one of the best things he'd done although a banjara.

My ideal man?

I don't know.

I need a friend - my best friend, my lifeline - although after Genius awakening me to realize that best friends are just nothing more than facades and masks we have over our faces to have more rights over someones' life - we do care about them deeply but isn't it true that we also subtly have this power to emotionally manipulate them according to what we believe/feel/think is right for them. Just because we've known them and we've had intimate/close moments of joy, sorrow, ups and downs together...

My ideal guy would probably be a wife! 

A wife = who is not a guy or a girl - a responsibility taken by anyone - a gender-neutral job.

A wife = who'd care for me as much as I care for them

A wife = who respects me as much as I respect them

A wife = a gender-neutral job profile, to give care and love and just receive back then...

A wife = the feminine nurturer, nourisher and care taker

A wife = gives a space for the masculine to be vulnerable

A wife = compliments their partner in characteristics and traits

A wife = someone who can balance the yin - yang energy of their partner

A shiva to the parvathi, a lakshmi to vishnu, a dattatreya to anasuya, a devayani to karthikeya.

a ranjha to heer, a laila to majnu...

I can merely only give examples... but if you find a person who fits your unmade checklist of a partner and you find everything you've been looking for when you weren't really looking or were about to give up... and if you believe you cannot live another day without them...

that's your person, your zing. don't let them go.

september; a second chance

I often feel like Septembers are when we are offered a second chance.

My August is always a rush, a dash n run, a no time to breath.

But yeah, its our responsibility to pause, breath, rest, rejuvinate and then proceed to the chaos that always awaits us.

And I'd like to think September offers that.

The last 123 days of year, things will start to form a pattern, a routine, a seamless flow; now more than ever.

Despite the chaos and frenzy in the last couple of months, september welcomes a new breeze with a touch of autumn in the air.

Its refreshing, and nice. A calm rushes over everything and my soul. The air is calmer. My nerves are calmer. I know the year can end in a big bang! ✨️✨️

I hope everyone has a great september ahead!! 😘😘

Until later,

RH
