Answer:

Thymine is used in replication while uracil is used in transcription.

Explanation:

<em>New cells can only be created after transcription has taken place. Replication results in mRNA strands while transcription creates new DNA. Transcription happens outside the nucleus and replication happens inside the nucleus. Thymine is used in replication while uracil is used in transcription.</em>

DNA replication is a process whereby DNA makes a copy of itself while DNA transcription is a process whereby a messenger RNA is synthesized from a DNA strand.

Both processes involve the building-up of nucleotides or purine.pyrimidine bases. Replication involves building up of cytosine, guanines, adenine, and thymine bases while in transcription, the thymine base is replaced by uracil base.

Hence, the correct answer is that <u>Thymine is used in replication while uracil is used in transcription.</u>

Answer:

The correct answer is b.Amplify the gene using PCR. Insert the gene into a plasmid vector. Transform the vector into the bacteria.

Explanation:

If I have a very small amount of gene for a fluorescent protein than the first step is to amplify the gene so that appropriate protein can be produced. PCR is the instrument that is used to amplify the protein.

So after amplification of the gene, the plasmid vector will be used in which the gene will be inserted because the plasmid vector is used to insert this gene in host cells where protein will be expressed.

The final step will be to transform bacteria with recombinant plasmid so that plasmid can make its copy and express a fluorescent protein in bulk.

How many atp equivalents are consumed in the conversion of each of the following to a glucosyl residue in glycogen?

Nina [5.8K]

<h3><u>Answer;</u></h3>

Dihydroxyacetone phosphate - 1

Fructose-1,6-bisphosphate - 1

Pyruvate - 13

G-6-P - 1

<h3><u>Explanation;</u></h3>

1) Dihydroxyacetone phosphate = 1

G1P + GTP --> UDPG + PPi two P is equivalent to 2 ATP --->2 ADP + Pi) Therefore, two ATP equivalents - but UDP is the product and only one P needed

2 DHAP --> F1,6-BP -->F6P --> G6P -->G1P -->UDPG --> glucosyl residue

2) Fructose 1,6-bisphosphate = 1

3) Pyruvate = 13

2 pyr + 2 ATP --> 2 OAA

2 OAA + 2 GTP --> 2 PEP

2 PEP --> 2 2PG --> 2 3PG

2 3PG + 2 ATP --> 2 1,3 BPG

2 1,3 BPG + 2 NADH --> 2 G3P

2 NADH = 6 ATP

2 G3P --> DHP + G3P --> FDP -- > F6P + P

F6P --> G6P --> G1P

G1P + UTP --> UDPG + PP

4) Glucose-6-phosphate = 1

G6P -->G1P G1P + UTP --> UDP-GLC + 2 Pi

UDP-Glc + glycogen --> glycogen+ 1 Glc
