There are three phases of stem cells mitosis, gene expression, and differentiation.

<h3 /><h3>What are stem cells?</h3>

Stem cells that are totipotent or omnipotent. programmable stem cells. Multiple-potency stem cells, stem cells with oligopotency, the body's building blocks are stem cells, which are cells that give rise to all other cells with specific roles.

Daughter cells are created when stem cells divide properly in the body or a lab to create additional cells. Most stem cells are found in the bone marrow.

They divide at this stage to produce new blood cells, Once fully developed, blood cells leave the bone marrow and travel into circulation.

Therefore stem cells develop into different cells through differentiation.

you are a biochemist working for a pharmaceutical company. you have been tasked with identifying a sample of nucleic acid. it is
Lorico [155]

The sample that is being discussed in the problem can be either DNA or RNA.

DNA and RNA are both very important molecules. Both of these hold immense value in biology since they store all the vital information required for living. The basic structures of the two are quite similar; the only difference is that DNA is double-stranded while RNA has a single strand.

DNA and RNA molecules both contain a five-carbon sugar (ribose), a phosphate group, and a nitrogenous base. Except for cytosine, guanine, and adenine, the fourth part is the phosphate group that exists in both. RNA has Uracil while DNA has Thymine.

Since it has not been mentioned here what the fourth part might be, the sample might be a DNA or an RNA molecule.

Why is it necessary for the DNA to replicate prior to cell division?
kherson [118]
The answer is b. because you wouldn't want a daughter cell that didn't have <em>all </em>necessary to be a complete cell, and this could be messed up if the DNA didn't replicate prior to cell division

Part A: A scientist examines a fruit fly gene involved with the regulation of body development. A section of the DNA sequence fo
Leokris [45]

Answer:

Part A: Thr-Leu-Val

Part B: ACC-UUG-GUU

Explanation:

When you transcribe a DNA sequence to mRNA, you need to remember that in RNA there is no Thymine (T), instead it has Uracil (U). So the base pairings would be like this compared to DNA base pairing:

DNA                RNA

A-T                  A-U

T-A                  T-A

C-G                 G-C

G-C                 C-G

Given the sequence the transcription will be as follows:

DNA :   TGG - AAC - CAA  

mRNA: ACC - UUG - GUU

Next, to translate it into amino acids, you will use the chart. Now amino acids pair in codons (3 base pairs at a time).  Let's take the first codon in your sequence:

ACC

1st  2nd   3rd

 A     C       C

Using the column on the left, find the row that matches it, so in this case A.

At the very top, there is another row of letters, looking at the row of A only, look for the column of the second base which is C.

Lastly, look at the right most column and find the letter that matches the third base within the box where A and C intersect. In this case, C is your third base.

The amino acid where all three intersect is your first amino acid which is Thr.

Just do this for the next codons and you will come up with the answer.
