<span>A single stranded nucleic acid that plays a role in protein synthesis is known as the messenger RNA or mRNA (messenger Ribonucleic Acid). The other two types of nuclei acids are transfer RNA or tRNA and ribosomal rNA or rRNA. These nucleic acids are involved in cellular division in cells, during which transcription and translation occurs.</span>
Natural selection is the only option that relates to the evolution theory
No , both strands are replicated in opposite directions , which gives rise to the name " leading " and " lagging " strands as one strand is replicated faster than the other . DNA is replicated only from 5' to 3' so only one strand can be replicated in the 5' to 3' continously ( leading ) while the other is in the opoosite direction . u probably wont understand this mechanism easily through words so i suggest u watch a video on youtube if u still dont get it !
Some factories drain chemicals into the local water supply. Some factories also release smoke and chemicals into the air.
