<span>The right answer is: A
A) The molecule is digested by exonucleases because it is not protected at the 5' end. (correct)
B) The molecule is digested by restriction enzymes in the eukaryotic cell's nucleus. (false it is digested by exonucleases due to the absence of the 3'cap and the 5'tail)
C) The mRNA cannot exit the nucleus to be transcribed without the 5' cap and poly-A tail. (false, to be TRANSLATED and not to be transcribed)
D) The mRNA molecule attaches to a ribosome and is translated at a much slower rate. (false, it doesn't have a role to play in translation)</span>
Answer:
yes
Explanation:
The four primary functions of the skeletal system are to support muscles and tissue, protect the vital organs, allow movement of bones and muscles and serve as the storage center for immature blood cells and minerals.
Answer:
Chlorophyll >thylakoid> grana >chloroplast.
Explanation:
Two nucleotides on the same strand form a <u>Phosphodiester bond </u>while two complimentary bases on opposite strands form <u>Hydrogen bonds</u>. An a-t base pairing forms <u>2</u> such bonds.
The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.
Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.
