Which method(s) can be used to join double-stranded breaks in DNA? (choose all that apply)
Amiraneli [1.4K]

Answer:

Option (a) and (d).

Explanation:

The breaks in DNA molecule may occur due to replication error and oxidizing agent. The double-stranded breaks in DNA can be corrected by Homologous end joining and non homologous end joining.

Homologous end joining is used to repair the DNA present in G2 nad S phases of the cell cycle. The homologous sequences of DNA is used to repair the DNA. Non homologous end joining occurs in the cell present at G0 and G1 phase of the cell cycle. The DNA broken ends are juxtaposed and later rejoin together by DNA ligase.

Thus, the correct answer is option (a) and (d).

explain how a mutation is an individuals DNA occurs, and describe the effect it may have on the individuals trait. I need help o
Mazyrski [523]
Mutations are spontaneous and occur at random however there are some mutagenic agents which increase the chance of this happening such as radiation exposure. If it is a point shift mutation then only a few bases on the dna sequence are changed so only changes a few of the amino acids in that chain (such as inversion of a base). If its a frame shift then the base sequence is altered so much so that every amino acid from after that changes (such as deletion of a base) which can create things such as cri-du-chat syndrome which results from a piece of chromosome 5 is missing. Hope this helps:)

How might optimization be expressed in older adults' sexual activity?
ra1l [238]

Optimization refers to the activity of making the most or best efficient use of a resource of situation. Optimization suggests that it is probable to sustain performance in some areas via spontaneous practice and the application of new technology.  

The older adults get involved in numerous sexual activities, companionship is essential to age individuals. The optimization in older adults’ sexual activity can be expressed by getting involved in more kissing, cuddling, and fantasizing in comparison to intercourse for satisfying the sexual activity.

mrs_skeptik [129]

Answer:

d. None of these  

Explanation:

Probably the identical sequence found in both species<em> </em>is an<em> ultraconserved sequence. </em>

An <u>ultraconserved element</u> is a particular DNI sequence that remains exactly the same through evolution, with almost no modification, and that is shared by at least two completely different species.

These ultraconserved DNI portions seem to be highly essential for life. However, their function could not be determined yet. Most of them do not codify for proteins, but they could play a significant role in gene regulation.

It is suggested that these sequences are so significant for life that only a small change would compromise the organism´s aptitude.
