Answer:
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Answer:
UACUUGGUAAGUCAUAC
Explanation: this is the rna molecule transcription
for reference in DNA A matches with T and G matches with C but in rna transcription you match A with U whenever theres an a , but if theres a T involved then thats when you add an A in the rna in conclution RNA :A-U G-C ( rare T-A) DNA :A-T and C-G
Answer:
e) phosphorylation to phosphoenolpyruvate
Explanation:
phosphoenol pyruvate is not the fate of the pyruvate . pyruvate can convert into the phosphoenole pyruvate in the reverse of the glycolysis which will utilize the ATP . So , this can not be the fate of pyruvate because in the breakdown of the glucose through glycolysis pyruvate is the end product and phosphoenol pyruvate is the intermediate .
Answer:
PPTt
Explanation:
Let the gene for flower colour be denoted by P. P is the dominant allele and produces purple colour, p is the recessive allele and produces the recessive colour. Let the gene for stem height be denoted by T. T is the dominant allele and produces tall stem, t is the recessive allele and produces short stem.
A test cross was done which means that one of the parents was homozygous recessive for both the traits i.e. pptt
In the progeny all the flowers had purple colour which is only possible if the test parent was homozygous dominant for the trait i.e. it was PP
PP x pp :
P P
p Pp Pp
p Pp Pp
As evident, all the flowers will have Pp genotype and hence purple colour.
In the progeny, around half of the flowers had tall stems and half had short stems. This is only possible if the test parent was heterozygous for the trait i.e. it was Tt
Tt X tt :
T t
t Tt tt
t Tt tt
As evident, half plants have Tt genotype so they will have tall stems. Half of them have tt genotype hence will have short stems.
Hence, combining the genotype for two traits we obtain the genotype PPTt of the original test pea plant.
I would help but the picture aint loading
