In E. coli, there is a mutation in a gene called dnaB that alters the helicase that normally acts at the origin of replication.
kvasek [131]

Answer:

When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.

Question 1
weqwewe [10]

The correct statement is D. The mental region is superior to the nasal region.

The different terms in the statements are anatomical terms. We use them to describe the regions and locations of organs.

<h3>Why are the other statements incorrect</h3>
  • The pubic region is inferior to the pelvic region: inferior means is lower. However, the pubic region is higher than the pelvic region.
  • The olecranon region is distal to the carpal region: we describe organs and bones in relation to the nearest parts to the axis of the body. In other words, we describe things from proximal (to the column and head) to distal. So, the carpal is distal to the olecranon.
  • The heart lies dorsal to the vertebral column: dorsal means behind. The heart lies ventral to the column. In other words, towards the front of it.
  • The sternal region is lateral to the axillary region: we describe locations from proximal to distal, so the axillary region is lateral to the sternal region.

In conclusion, the correct option is: The mental region is superior to the nasal region because the mental region is the one that is above the nasal one in the skull.
