Nucleotides lining up along the template strand according to base pairing rules process helps to preserve the genetic information stored in DNA during DNA replication
Option D
<h3><u>Explanation:</u></h3>
The DNA is a semi conservative molecule from the genetic information storing point of view. The genetic information is stored there in form of the alignment and arrangement of the nitrogen bases. These nitrogen bases are replicated just in order to conserve the genetic information.
During protein synthesis, same nitrogen bases get denoted in the RNAs and this gives the particular protein which is required in the body. No molecule present in the body can destroy the DNA and its alignment. It’s conserved as long as no external molecule or force destroys it. So it’s conserved in a very safe way.
Answer:
Jaws and a swimming bladder
Explanation:
A defining characteristic between sharks and rays that distinguish them from ray-finned fish is the *possession of jaws in sharks* and rays;and the *possession of swimming bladder in ray-finned fishes*.
Characteristics of sharks and rays are as follows :
They are cartiiliginous fishes; they possess *strong jaws* lined with teeth; body dorsoventrally flattened, fusiform (spindle shaped) with heterocercal tail(diphycercal in Chimaeras); paired fins; *no swimming bladder or lungs*; pelvic fins in males often modified to form clappers; Gill arches internal to gills; reduced notchord; lateral-line system; paired nostrils; internal nares absent; separate sexes; internal fertilization and direct development; oviparous, oviparous, or ovoviviparous. Examples include, Spiny dog fish or dog shark, Ray Raja, Chimaera.
Characteristics of ray-finned fishses:
They generally lack paired fins; no internal nares; *air sacks usually function as swimming bladder*; skeleton usually well ossified. Blind olfactory sacs (do not open into the mouth); Tail homocercal. Examples include Tilapia, Claris,and Polypterus.
1. spines to protect plants against animals seeking water.
2. A waxy coating on leaves to reduce water loss.
