Continuous feeders are aquatic animals that constantly feed by having water filled with food particles (for example, small plankton or fish) entering through the mouth. In addition, they do not need a storage area, such as a stomach, for food. Now Discontinuous feeders must hunt for food on a regular basis; they need a storage area, such as a stomach, to house food until it is digested.

Which best summarizes the process of protein synthesis?

Tpy6a [65]

Answer:

RNA moves the DNA code to the ribosomes for protein synthesis

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA genetic message and assembles the brand-new polypeptide chain. tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.

Assume that you have 1 mL of a solution of amylase (an enzyme) at a concentration of 15 mg protein/mL. Calculate the volume of d

lidiya [134]

Answer:

42,5 mL

Explanation:

We need to use the serial dilution formula beacuse we start with a stock concentrate solution and we need to prepare a new less concentrated one.

$DF=\frac{Vi}{Vf}$

<u>DF in the dilution factor, Vi is the initial volume and Vf is the final volume.</u>

The first step is to have the same measurment unit so we need to convert 345 µg to mg.

we know that 1 µg equals 0,001 g, hence:

$345 µg = 0,345 mg$

now the final volume is 0,345 mg protein/ mL and the inital volume is 15mg protein/mL, both of them are in the same unit so we can use the formula

$DF= \frac{15mg protein/mL}{0.345mg protein/mL}$

$DF= 43,5 mg protein/ mL$

Now since the question said that we already have 1.0mL of the amylase stock solution we need to subtract that 1.0mL to the 43,5 mg protein/mL

$43,5mL-1,0mL = 42,5 mL$

So, we need 42,5 mL of diluting buffer if we want a final concentration of 345 µg protein/mL (0.345 mg protein/mL)
