In a dominant cross, the chance of the dominant phenotype showing up in one of the offspring is 3/4, since the dominant genes are being shown here.
<u>Answer:</u>
CCGAGU
<u>Explanation:</u>
DNA transcription:
DNA transcription is the process through which DNA double helical strand is converted into single stranded RNA molecule.
During transcription two strands of DNA are named differently i.e Template strand and coding strand.
Template strand:
Strand from which RNA is producing is known as template strand while
Coding strand:
The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.
Correct Answer:
Template strand from 5' to 3' reads GGCTCA. and
In this question CCGAGT is coding strand.
RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes
CCGAGU
Answer:
See the answer below
Explanation:
Let the disorder be represented by the allele a.
Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.
Since the four adults are carriers, their genotypes would be Aa.
Aa x Aa
Progeny: AA 2Aa aa
Probability of being affected = 1/4
Probability of being a carrier = 1/2
Probability of not being affected = 3/4
(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2
(b) The chance that the third child of Sara and James will be free of the condition = 3/4
(c)
(d) If someone has no family history of the disorder, their genotype would be AA.
AA x aa
4 Aa
<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0
(e)
(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0
Answer:
Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides. In the human body.
Explanation:
Disaccharide, also called double sugar, any substance that is composed of two molecules of simple sugars (monosaccharides) linked to each other. ... The three major disaccharides are sucrose, lactose, and maltose.
Three common disaccharides:
#sucrose — common table sugar = glucose + fructose.
#lactose — major sugar in milk = glucose + galactose.
#maltose — product of starch digestion = glucose + glucose.
