  • Evolutionary study: To gather archaeological samples and analyzed for To profile DNA from blood, hair, and skin cells for criminal identification and forensics – – – – Stages of PCR PCR is divided into 3 stages: Denaturation Anneal – – ExtensionThe denaturation stage – – The double-stranded DNA sample is…
  • The annealing stage – – primers anneal to the DNA strands when the temp.
  • Melting Temperature Formula (18-25 bp range) – – Tm = 2(A+T) + 4(G+C) – – The forward and reverse primers should be having similar Tm, or else amplification will be less efficient.Melting Temperature should be between 55C and 65C.
  • The simplest API function iscalcTm, which uses nearest-neighbor thermodynamics to calculate the melting temperature of a provided DNA sequence: – – import primer3 – thermodynamic functions andcalcHeterodimer.
  • All three functions return a namedtuple: – – from primer3 import calcHeterodimer – res = ‘TTGGTCCCATAAGGGTCGG’) – print(res) – – thermoresult( – structure_found=True, – tm=39.92795428766294, – ds=-370.12644214999796, – dh=-127200.0, – dg=-12405.28396717814, – align_end_1=16, – align_end_2=17 – ) – – print res.tm – 39.92795428766294 – – For more detailed documentation and…

Development Guide: Web Games using JavaScript

  • As we are developing a 2D game using HTML and JavaScript, here is how we can initiate the canvas in HTML: – – canvas id=canvas width=500 height=500/canvas – – – id is used to access the HTML canvas in JavaScript.
  • In order to get the context of the canvas, we would use getContext function of the canvas object as follows: – – let context = canvas.getContext(2d); – – As you can see in the previous line of code that we have specified 2d as the parameter of the getContext (for…
  • The source code to draw the complete image into canvas is as follows: – – let cardsprite = new Image(); – cardsprite.src = cardsprite.png – – function draw() { – let width = cardsprite.width; – let height = cardsprite.height; – canvas.width = width; – canvas.height = height; – context.drawImage(cardsprite, 0,…
  • draw function is created; in that function, first the width and the height of the cardsprite is saved in the temporary variables and then the canvas size is resized to the cardsprite width and height (you may resize the image, but that is not the scope of this article).
  • The code for animation (JavaScript file) is as follows: – – let canvas = context = canvas.getContext(2d); – – let cardsprite = new Image(); – cardsprite.src = cardsprite.png – – let width; – let height; – let singleCardWidth; – let singleCardHeight; – let xframe = 0; – let yframe =…

  • To talk to a Google API, you need theGoogle APIs Client Library for Python, specifically and install the library in your usual way, for example: – – $ pip install -U google-api-python-client # or pip3 for 3.
  • Now craft the following lines of code in your command-line tool, using the instead: = # copied from project credentials VERSION, developerKey=API_KEY) – – Take the API key you copied from the credentials page and assign to theAPI_KEYvariable as a string.
