The majority of bacteria have a cell envelope. which component of the cell envelope is found in only some bacterial cells?
lesya [120]

The majority of bacteria have a cell envelope component which serves as an outer compartment.

Explain the Plasma membrane components.

The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells.

A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells. A semipermeable lipid bilayer makes up the plasma membrane. The movement of materials into and out of the cell is controlled by the plasma membrane.

A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it offers a stable environment inside the cell. And that membrane serves a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell.

Hence, the correct answer is the outer membrane.

Which is an example of an insertion mutation that changes all of the amino acids that follow the mutation?
astra-53 [7]

Answer:


2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG

Explanation:

Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!

In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G

In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.


In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.


In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.


Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.
