Answer:
Different <u>tissue</u> working together to perform a particular job are called <u>organs</u>.
Explanation:
DNA is deoxyribonucleic acid while RNA is ribonucleic acid !
DNA has base pair of adenine guanine thymine and cytosine.....while RNA has adenine guanine cytosine and uracil !
DNA is always double helix while RNA is mainly single helix !
DNA contains genetic info for 99℅ of organism while RNA is being catalytic and unstable than DNA is only present as genetic information holder in 1℅ !
DNA does not involve in protein synthesis directly but RNA has to !
for more difference, comment !
These two phyla are Annelida and Arthropoda. The Annelids are segmented worms, and include earthworms<span>, and </span>leeches. These worms occur widely, in marine, aquatic and terrestrial habitats. The Arthropods are invertebrates with an exoskeleton<span>, a </span>segmented<span> body, and paired jointed </span>appendages<span>. These include</span><span> </span>insects<span>, </span>arachnids<span>, </span>myriapods<span>, and </span>crustaceans<span>. </span>
Answer:
both shares plasma membrane, ribosomes, cell membrane
Explanation:
These questions are related to the extraction of DNA using detergents and ethanol.
1. Consistency and texture- the extracted DNA is white, spongy and moist or slime in nature.
2. Salt is used during the extraction process as the DNA is negatively charged molecule and to neutralize the negative charge which will allow the formation of precipitate.
3. The DNA is soluble in aqueous solution as the DNA is a negatively charged molecule therefore the negative charge makes it a polar molecule and it can form the interactions in the aqueous solution.
4. RNA could be present in the aqueous solution along with the DNA as both are the nucleic acid.
5. The base-pairing rule was suggested by the Chargaff who proposed that Adenine binds thymine and guanine binds cytosine.
5. The binding of adenine to thymine involves two hydrogen bonds and between guanine to cytosine involves three hydrogen bonds.
