Need help with this please...

The correct sequence of events occurring during transcription is

marin [14]

Firstly, the enzyme, DNA Helicase breaks the Hydrogen bonds between a specific region of the DNA molecule and unwinds the duplex DNA molecule at the targeted gene sequence site.
Then, RNA Polymerase binds at the 3` site of the gene sequence of the sense/coding strand(only one strand) that acts as the template for mRNA synthesis. RNA Polymerase then matches free nucleotides by complementary base-pairing(A-U & C=G), working in the 5`to3` direction. Hydrogen bonds then form between the complementary bases, holding the nucleotides in place. Each free adjacent nucleotide is joined at 3` ends by Condensation reactions with the other to form Phosphodiester bonds.
Once the mRNA molecule is formed, it is separated from the synthesis complex and leaves the nucleus through pores in the nuclear envelope to moves towards ribosomes for Translation.
Lastly, the DNA double helix rewinds by forming Hydrogen Bonds.

Signs and symptoms that a woman should report immediately to her health care p rovider include:________.

solong [7]

The question is incorrect.

the correct question is Signs and symptoms that a prenant woman should report immediately to her health care provider include:________.

a. vaginal bleeding

b. rupture of membranes

c. heartburn with severe headache

d. decreased libido

e. urinary frequency

Answer:

a. vaginal bleeding

b. rupture of membranes

c. heartburn with severe headache

Explanation:

A pregnant woman should report immediately about vaginal bleeding

, rupture of membranes

, and heartburn with severe headache to her health care provider.

A) Vaginal bleeding: vaginal bleeding is uterine bleeding, which is common in the earlier stage of pregnancy but if it is continous it can be symptoms of miscarriage, so one should immediately contact her healthcare provider.

B) Rupture of membranes: If any pregnant women experience rupture of membrane, it causes steady leakage of fluid from the vagina. If the rupture is preature it can cause some complications in the baby such as premature birth, infection, and cord compression.

C) Heartburn with severe headache: if a woman experiences heartburn with severe headache during pregnancy, she should immediately contact her healthcare provider as it can be symptoms of preeclampsia (condition develops during the second half of pregnancy).

Hence, the correct options are a) vaginal bleeding

, b) rupture of membranes

, and c) heartburn with severe headache

The ligation you carried out in Laboratory 3 can result in a number of plasmids, but none of these have been replicated in a bac

Ipatiy [6.2K]

Nicked circle is the reason.

Explanation:

During recombinant DNA technology the gene of interest is ligated to plasmid DNA by excision with molecular scissors or endonuclease enzyme and ligated with enzyme ligase.

Enzyme ligase catalysed by ATP seals the nicks by making phosphodiester bonds in the ds or ss DNA and release of ADP.

The ligation in the plasmid did not occur properly hence the replication is interrupted hence no new plasmids with gene of interest replicated in the ligation carried out.
