These proteins allow substances to enter that wouldn't be able to otherwise. Only small hydrophobic substances can enter cells. However, these proteins aid crucial substsances in entering the cell.<span />
Answer:
characterized by presence or absence of antigens
the blood types are A, B, O, AB
Explanation:
There are two antigens and two antibodies that are mostly responsible for the ABO types. The specific combination of these four components determines an individual's type in most cases. Erythrocytes and serum were related to the presence of antigens on these erythrocytes and antibodies in the serum. these antigens are A and B, and depending upon which antigen the erythrocytes express, blood either belonged to blood group A or blood group B. A third blood group contained erythrocytes that reacted as if they lacked the properties of A and B, and this group was later called "O" blood group. The fourth blood group AB, was added to the ABO blood group system. These erythrocytes expressed both A and B antigens.
Blood group Antigen present on RBC Antibodies in serum Genotype(s)
A antigen A anti-B AA or AO
B antigen B anti-A BB or BO
AB both A and B antigen none AB
O none anti-A and anti-B OO
Answer:
<h2>RrYy and rryy
</h2>
Explanation:
1. As given; Round seeds (R) are dominant on wrinkled seeds (r),
Yellow seeds (Y) are dominant on green seeds (g).
In a testcross, between an unknown genotype and a homozygous recessive with wrinkled and green seeds (rryy).
offspring are:
Round and yellow are 53; genotype (R_Y_)
round and green are 49; genotype (R_yy)
wrinkle and yellow are 44; genotype (rrY_)
wrinkled and green are 51 ; genotype (rryy)
Here, the genotype of parents of these offspring would be RrYy and rryy.
Answer:
The answer is C.
Explanation:
The example process given in the question is describing the creating of a cDNA Library. cDNA or Complimentary DNA is copy of the DNA that is taken from a messenger RNA (mRNA), which is what is done with the reverse transcriptase. And the process described as cloning the resulting DNA into plasmids is the part where the library is created. The resulting DNA is put into host organisms and stored there for further investigation or use.
I hope this answer helps.
