What could happen if a mutation in a gene caused a hydrophobic amino acid in a polypeptide to be replaced by a hydrophilic amino
Marysya12 [62]

The new hydrophilic amino acid would not form the same interactions with hydrophobic R groups. As a consequence,   protein's 3D structure would likely be affected.

Different types of amino acids have different properties and thus form different interactions. For example, hydrophobic amino acids (water-repelent) such as alanine, valine, leucine, isoleucine, proline, phenylalanine, cysteine and methionine. participate in van der Waals type of interactions. They often form the hydrophobic core of the protein which doesn’t interact with water surrounding.

On the other hand, hydrophilic amino acids (arginine, asparagine, glutamine, aspartat..) are polar, can dissolve in the water and can join the hydrogen bond network.

A species of fly has two alleles for the length of their legs. The allele for long
postnew [5]

Answer:

According to Hardy Weinberg law (p+q)2=1 where p is fequency of one allele and q is the frequency of another allele.

Explanation:

According the question

 q represent the short legs and 33 of 100 organism have short legs.

    As a result the frequency of q with respect to the 100 organism is 33/100

                                                                                                                   =0.33

Therefore q=0.33

     we all know that

                   (p+q)2=1

              ∴  p+q= 1

              ∴  p=1-q

                   p= 1-0.33

                    p=0.67

The frequency of p is 0.67

you are studying a bacteria plasmid that contains 5 operons and 15 genes. how many transcriptional promoters are on this plasmid
mojhsa [17]

Numerous catabolic operons have their transcription controlled by glucose. The three enzymes needed for conversion are encoded by the operon's five structural genes.

<h3>How many genes are there in an operon?</h3>

Operons have a transcription promoter at the beginning, two to twelve genes on average, and a transcription terminator at the conclusion (Zheng et al. 2002; Lawrence 2003).

<h3>Yes, there is just one promoter for operons.</h3>

An operon is a group of genes that all use the same transcriptional promoter. Every operon contains regulatory DNA sequences that act as binding sites for regulatory proteins that either promote or inhibit transcription.

<h3>The promoter is a 3 or a 5?</h3>

An area of DNA known as a promoter is where RNA polymerase starts to transcribe a gene. Promoter sequences are often found directly in the genome.
