Answer:
The most accurate measurement is 2.829 cm.
Explanation:
We can round the decimals to a certain accuracy in order to make further calculations easier.To round a number to the nearest hundredth ,check the next place value to the right (the thousandths). If it's less than 5, remove all the digits to the right. If the place value is 5 or greater than 5, just add 1 to the previous digit (the hundredths place digit) and drop all other digits to the right.
In other words, to round off a decimal number, the procedure is as follows; if the digit to the right of the required number is a 5 or greater, add 1 to previous digit and drop all the remaining digits. If the required number is less than 5, do not change the previous digit and remove all the remaining digits.
Here, a piece of metal with a length of 2.83 cm was measured using four different devices. The obtained measurements are 2.837 cm, 2.829 cm, 2.812 cm and 2.805 cm.
Thus, the first measurement 2.837 cm can be round off to 2.84 cm. The second measurement 2.829 cm can be round off to 2.83 cm. The third measurement 2.812 cm can be round off to 2.81 cm and the fourth measurement 2.805 cm can be round off to 2.81 cm.
So the most accurate measurement is the second one, 2.829 cm which can be round off to 2.83 cm.
Answer:
<u>Both</u>:
- The start codon is often AUG
<u>Eukaryotic cell only:</u>
- The larger subunit of the ribosome is 60s.
- The ribosomes initially binds the 5' end of mRNA.
<u>Prokaryotic cell only</u>:
- The ribosome is 70s
- Translation occurs in the cytoplasm
- There are multiple ribosome binding site
Explanation:
- AUG is the common start codon for both eukaryotic as well prokaryotic cells. In eukaryotic cell, it codes for methionine . While in prokaryotic cell, it codes for formyl methionine.
- In prokaryotic cell, ribosomes are found in cytoplasm, hence the translation occurs in cytoplasm.
- Eukaryotic ribosome consists of two subunits; 40s and 60s(larger subunit)
- Prokaryotic ribosomes have 70s ribososme, which consists of 50s and 20s subuints
- in eukaryotic cell, 40s ribosome initially binds to the cap at the 5' end of mRNA.
- Bacterial mRNA contain multiple ribosome binding sites.
When a scientist say's organisms have the same universal genetic code it mainly means that the
"organisms use the same four nucleotide bases." Now <span>organic molecules that serve as the monomer units for forming the nucleic acid polymers.
