What is in DNA why can it not read the uracil nitrogenous base during transcription? May I have answer in the molecular level?

The easier way that I know is that you have to find the derivative of f(x) = 6x^2 - 4. Then substitute -2 to x. Note: Use the easier way in finding derivatives.

Is there any difference between the two? 1. Descriptive statistics which is one of the operations of statistics. 2. Descriptive statistics which are numbers used to describe a certain sample or population.

Solution: dy/dx=( 1/3 π(〖6)〗^(2 ) h- 1/3 π(〖3)〗^2 h)/(6-3) dy/dx=( 1/3 π36h- 1/3 π9h)/2 dy/dx=( 1/3 π36h- 1/3 π9h)/2 dy/dx=(12πh-3πh)/3 dy/dx=9πh/3 =3πh Solution: dy/dx=2/3 πrh At r = 6: dy/dx=2/3 π6h =4πh

Homework Statement Use the formula V = (1/3)pi r2(h) for the volume of a right circular cylinder to find a. the average rate at which the volume of a right circular cylinder changes with the radius r as r increases from 3 cm to 6 cm. b. the instantaneous rate at which the volume of...

thank you but why should I let y be equal to u+90? since y approaches 90 degrees, to evaluate the limit, what I have learned is to just substitute y= 90 degrees. so how is that?

what "u"? where should I substitute it? thank you

please give a hint on how to solve this. the limit of (2y - 180 degrees)/(cos y) 'as y approaches 90 degrees.' the answer here is -2. I need a 'hint' for me to arrive at -2. thank you

thank you I got it thank you for the 'hint'

Can someone answer this problem for me? please! What is the limit of ((sin a)(sin 2a))/(1- cos a) as 'a approaches 0.' they say the answer is 4. I really don't get it. thank you P.S.: Is sin a + cos a = 1

A function is defined as a set of ordered-pairs where ... But can we consider equations as functions? Some says 'yes'. Some says 'no', because according to them, equations are not actually functions. They are just used to define/represent functions. example: y=4x+1/f(x)=4x+1. Can...

Can we consider all whole numbers as fraction?why?
