A is true, the others are not. I would assume they count the mRNA and tRNA in protein synthesis as 'double stranded'
Answer:
C. Because an RNA-seq reaction could tell if the fragments were encoded by the genome.
Explanation:
The combination of single-cell RNA sequencing (RNA-Seq) and bioinformatic tools to assemble and annotate sequence reads is currently the most common methodology used to obtain complete transcriptomes from individual cells. RNA-seq is a Next-Generation Sequencing (NGS) technology that enables the analysis of the entire transcriptome, thereby this method can be used to examine gene, allelic and ncRNA expression. In the last years, RNA-seq has become the gold standard technique for direct analysis of ncRNA expression profiles in biological samples and clinical research.
The question is:
What may be observed as a result of the described mutation in an individual?
<span>1) Skin cancer due to UV rays </span>
<span>2) Darker blue pigmentation </span>
<span>3) A lack of alterase for other functions it may serve </span>
<span>4) The release of a different pigment color
The correct answer is B.
In this theoretical molecular cascade, we have three key parts, the blue2 gene, the blue2 operator and the enzyme alterase.
The enzyme alterase stops the expression of the blue2 gene by binding to its operator, and therefore the blue pigment protein.
The blue2 operator has a specific binding spot for alterase. If this binding spot is changed due to a conformational change, the alterase would not be able to bind to the operator and the blue2 gene could express undisturbedly, resulting in increased concentration of the blue pigment protein.</span>
Answer:
b. Covalent bond between R groups
Explanation:
Disulfide bridge also known as disulfide bond or dicysteine bond is a type of interaction in which two cysteines of proteins come in close proximity with each other and form covalent bond with their functional (R) groups. The purpose of this bond is to stabilize the tertiary structure of a protein and make it more compact.
