Hello!
RNA in cells differs from DNA in that it is single-stranded and can fold up into a variety of structures.
RNA is the abbreviation for RiboNucleic Acid. It is a biological molecule that fulfills an important role by copying the information stored in the DNA (DeoxyriboNucleic Acid) and transporting it to the different proteins by folding into different shapes. Its name come from a Ribose molecule that is present in this single-stranded molecule.
Viruses don't have DNA, only RNA. They only replicate in the host's cells by copying their own RNA information.
Have a nice day!
The answer for the first question is B. mucus sweat and tears, all of those are defenses that the body uses when attacked. Now for the second option is A the answer because the first filter that a virus or a desease must pass is indeed the skin. Hope is good for you
Answer:
mRNA
Explanation:
The messenger RNA also called mRNA is the type of RNA that serves to carry the genetic information from DNA to the cytoplasm. The mRNA is formed by the process of transcription using the DNA template strand.
The mature mRNA enters the cytoplasm and joins with the ribosome. The nucleotide sequence of mRNA is translated into the amino acids sequence of polypeptides. The nucleotide sequence of mRNA is read in the form of triplet genetic codes by tRNA.
