Answer:

The results of genetic crosses can be predicted using a chart called a Punnett square. In a Punnett square, the possible male and female gametes of each parent are written across the side and top of the square. The interior squares represent every possible combination of gametes that could combine to form a zygote.

Explanation:

To fill in the square, look at the alleles of the games on the outside edges and bring them across and down to fill in the center of the square. If the offspring is heterozygous, we will write the capital letter in front of the lower case letter.

In the example below T=tall plants and t= short.

Answer:

- Protein sequence: Met-Pro-Gly-Lys-Ile-Arg-Arg-Pro-Pro-Gly-Thr-Pro-Leu-Phe-Gly-Lys-*

- DNA 5' UTR: ATTTTAGCC

- RNA 3' UTR: UAAAAAUAAAAU

Explanation:

Transcription is the process in which a DNA sequence (e.g., a gene) is used as template (transcribed) in order to synthesize an RNA molecule, usually a messenger RNA molecule, which is then used as template to produce a polypeptide sequence (protein) in the ribosomes. In RNA, Thymine (T) bases are always replaced by Uracil (U) bases. An mRNA strand is formed in the 5′ to 3′ direction. Each triplet of nucleotides is referred to as a codon and the resulting mRNA strand is translated starting from codon AUG (Methionine), while there are three different stop codons or 'or termination codons' in the genetic code that terminate translation: UAG, UAA, and UGA.

How does lack of friction affect the energy of a roller coaster system?

iragen [17]

friction is a force that opposes motion and significantly slows the cars as they move on the track. While it is easy to believe that friction is bad for the ride, it is one of the forces engineers consider in ensuring passengers have a safe ride.

Consider the scenario in which Mutants A and B are grown in a medium that contains His, but does not contain Trp. For this scena

solmaris [256]

Answer: Attached below is the missing part of your question

answer

Mutant A

1) Requires tryptophan in the growth medium or from a donor mutant

2) Must form nanotubes to obtain it's required amino acid in this scenario:

Mutant B

1) Requires histidine in the growth medium or from a donor mutant

2) Does not need to form nanotubes to obtain it's required amino acid in this scenario:

Explanation:

Mutant A ( Over produces His and cannot produce Trp )

1) Requires tryptophan in the growth medium or from a donor mutant ; This is because the Mutant is an auxotroph for tryptophan.

2) Must form nanotubes to obtain it's required amino acid in this scenario:

This is because growth medium of the mutant is supplemented with histidine

Mutant B ( cannot produce His and overproduces Trp )

1) Requires histidine in the growth medium or from a donor mutant :

This is because Mutant B lacks the biosynthetic pathways necessary for histidine production

2) Does not need to form nanotubes to obtain it's required amino acid in this scenario: because the Mutant cell can easily take up the required amount of Histidine from its surroundings.
