the nontemplate strand of a portion of a gene reads 5'ACTGGTTCA. What will the sequence of the resulting transcript for this por
konstantin123 [22]

Answer:

DNA template sequence:  

5' TGACCAAGT 3'

RNA antisense sequence: 3' UGACCAAGU 5'

>>> RNA sense sequence (transcript) : UGAACCAGU

Explanation:

In the DNA molecule, four types of nitrogenous bases are found: cytosine (C), and guanine (G), adenine (A) and thymine (T). In DNA the bases pair up with each other in the following ways: A pairs with T by two hydrogen bonds, while C pairs with G by three hydrogen bonds. In RNA (i.e., transcript sequence), T is replaced by uracil (U). Moreover, the RNA nucleotide sequence is read in the direction 5' to 3'.

In the formula, E K = 1/2 • m • v 2 if mass (m) was doubled, how much would kinetic energy
Viktor [21]

Answer:

mass doubled makes KE twice as large

velocity doubled makes KE 4 times as large

Explanation:

Try it with an example

m = 4

v = 8

KE = 1/2 m * v^2

KE = 1/2*4 * 8^2

KE = 1/2 * 4 * 64

KE = 128

Now double the mass

m  = 8

v = 8

KE = 1/2 8 * 8^2

KE = 1/2 8 * 64

KE = 4 * 64

KE = 256 double what it started out as.

Now do it again.

m = 4     That was the original mass

v = 16

KE = 1/2 4 * 16^2

KE = 2 * 256

KE = 512

When the velocity is doubled the KE becomes 4 times as big.

4*128 = 512
