Explain why the genetic code is called a triplet code

1 answer:

6 0

The genetic code is broken down into a series of codons on the mRNA. Each codon consists of 3 nucleotides which (normally) correspond to a single amino acid (e.g. AUG codes for methionine). I say normally because you can also have a codon indicate a stop codon (so no amino acid will be inserted and instead the polypeptide chain will terminate). This mRNA molecule with its list of codons will instruct a ribosome to synthesize a protein according to this code.

This code is the set of rules - based on the triplet or codon. This triplet code is universal - all organisms use the same codons to specify the placement of each of the 20 amino acids in a protein.

Complete the sentence.

Luda [366]

Answer: Wide Area Network (WAN)

Explanation:

Correct on Edg; A Local Area Network (LAN) only works in a limited geographical range. A Wireless Local Area Network (WLAN) is the same, except that you can use it without the use of wired connections such as Ethernet cables. A Wide Area Network (WAN) allows you to reach a wider geographical range and often involves satellite signals and phone lines to connect devices over long distances.

Cell division is preceded by two growth phases. Besides growth, both G1 and G2

Leviafan [203]

Answer:

Explanation:

a. contain checkpoints that determine if the cycle will continue.

b. help move chromosomes to the new daughter cells.

c. produce more chromosomes before the cell divides.

d. grow and produce enough cytoplasm to fill two cells.

The correct answer would be that G1 and G2 contain checkpoints that determine if the cycle will continue or otherwise.

The cell cycle generally has three checkpoints that happen at G1, G2, and M phase of the cycle.

At G1 checkpoint, the integrity of the DNA of the cell is assessed to ensure that there are no damages and other conditions such as size and energy reserve are checked.

At G2 checkpoint, the cell is assessed for proper chromosome duplication to ensure that there are no mistakes or damages. The size of the cell and the amount of protein are also checked to ensure that the cell is ready for the active division phase.

At M checkpoint, correct attachment of the spindle fiber to the kinetochore of the chromosomes is checked. This checkpoint is also known as the spindle checkpoint and it happens towards the concluding phase of the metaphase stage.

The correct option is therefore, A.
