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.
<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:
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
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
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)
Answer:
Explanation:
c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.
a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.
b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.
The process of deoxyribonucleic acod starts with replication to transcription and translation.
Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.
transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.
Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).
Hence the arrangement is from C ---- A-----B.
Answer:
answer is d) all of these choices are correct.
Answer:
A predator is an organism that eats another organism. The prey is the organism which the predator eats.
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
