amino acid and RNA (or anticodon)

tRNA is used in the process of translation, which is when cells create a protein (polypeptide) from a strand of mRNA just came from the nucleus and is floating in the cytoplasm. This process occurs with the help of ribosomes!

A ribosome binds to an mRNA molecule, and tRNA's come swooping in one at a time to add amino acids to a growing polypeptide chain (protein).

On one end of the tRNA is a set of 3 RNA bases (called an anticodon), that binds perfectly to the opposing next 3 bases on the mRNA strand (called a codon) as it works it way through the ribosome. On the other side of the tRNA is the amino acid that the codon on the mRNA codes for, thus allowing the specific protein to grow 1 amino acid at a time.

Which is considered a modern space exploration project rather than a historical or future project?

Llana [10]

A.) Launch a satellite

Landing on the moon takes years to figure out. (How, when, what is the purpose, etc.) Capturing an asteroid is beyond difficult and would also take years to figure out how to do so.

Launching a space probe has yet to be done BUT we have had a satellite launched (hence how we get satellite images.)

Several experiments were required to demonstrate how traits are inherited. Which scientist or team of scientists first demonstra

Snowcat [4.5K]

Answer:

Frederick Griffith was the first scientist who discovered that cell contains some components that can be transferred to another cell and cause a permanent change(transformation) in the new cell.

To prove this he performed an experiment in which he took two strains of Streptococcus pneumoniae which contain one rough strain and one smooth strain. Rough strain was non-virulent strain and smooth strain was virulent strain.

So he injected smooth and rough strain in mice and saw that mice die when virulent strain is injected and survive when non-virulent strain is injected. Then he injected heat killed virulent strain in which mice survived.

Then he added remain of heat killed bacteria with live smooth strain of bacteria and infected the mice and saw that the mice was killed by non-virulent smooth strain of streptococcus.

After this experiment he concluded that cells contain some component later identified as DNA which can be transferred to new population of cells and transform these new cells.

The original regimen known as Pasteurization consisted of:

algol13

Answer:

The correct option is: 4. Heat at 62.8 degrees C for 30 minutes

Explanation:

Pasteurization is the process or technique of heating packaged as well as the unpackaged liquid food, to remove pathogens and extend the shelf life. In this process, the food is usually heated at temperatures below 100 °C.

Originally, this process involved heating the food at 72.2 °C for 15 seconds and 62.8 °C (145 °F) for 30 minutes, for batch pasteurization.
