What was marshall nirenberg and heinrich matthaeis contribution to our current understanding of the genetic code?
Julli [10]
Marshall Nirenberg and Heinrich Mattaeis contributed to out current understanding of the genetic code by discovering genetic codons. Their experiment deciphered the first of the 64 triplet codons in the genetic code by using nucleic acid homopolymer to translate specific amino acids. Their experiment cracked the first codon of the genetic code and showed that RNA controlled the production of certain types of proteins.<span />

Describe how you could simulates one of the cases from the computer simulation (Case 2, Case 3, or Case 4) using the basic labor
satela [25.4K]

In place of clicking on the touchpad for the Cases, I would boost in response to the visual incitements that would be linked with a reflex hammer with an accelerometer; the reflex hammer would move appropriately to the carrying of the picture on the screen by a programmed mechanical device. I wouldn’t use the reflex hammer’s sound however; it’s purely there to compute my reaction times (time of highest acceleration of movement of the reflex hammer deducted by time of reflex) instead of using the computer’s software at figuring reaction times, since I think the software is defective.

A particularly long radio wave has a wavelength of 1.5 x 10^9 meters. What is the frequency of this radio wave?
Phoenix [80]

Answer:

0.2Hz

Explanation:

The wavelength of a radiowave can be calculated this;

λ = v/f

Where;

λ = Wavelength (m)

v = speed (m/s)

f = frequency (Hz)

Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?

Hence, using λ = v/f

f = v/λ

f = 3 × 10^8 ÷ 1.5 x 10^9

f = 2 × 10^(8-9)

f = 2 × 10^-1

f = 0.2Hz

Economic importance of tilapia fish
dezoksy [38]

Answer:

Tilapia is one of the most productive and internationally traded food fish in the world. The production of farmed tilapia is among the fastest expanding food sectors in the world. Nile tilapia ( Oreochromis niloticus) is the most cultured freshwater species among the farmed tilapia and contributes about 71% of the world total tilapia production.

Tilapia is one of the most important farmed fish species worldwide (FAO 2018) and an important source of protein (Fitzsimmons 2000;Hai 2015). Due to its sequenced genome (Conte et al. 2017), easy reproduction, efficiency in adapting to diverse diets, high resistance to diseases and handling practices, and high tolerance of a wide variety of husbandry conditions, it is considered an ideal model in toxicological research.

In an animal cell, which two cell structures do newly-synthesised enzymes have to pass through to reach the external environment
ss7ja [257]

Answer:

Ribosomes, Cell membrane

Explanation:

Ribosomes can be described as structures which are involved in the production of proteins. Ribosomes are hence known to be the protein manufacturing units of a cell. As enzymes are also proteins,they will be synthesized in the ribosomes.

Cell membrane can be described as the membrane which is present outside the cell or which separates the cell from the external environment.

For an enzyme to pass through the external environment, it will have to pass through the ribosomes and the cell membrane.
