How many genes are shown on the section of normal DNA?
All of the genes are 'shown', but the B-strands of haemoglobin differ by one amino acid at position 6 (usually gutamic acid is espressed here, but in sickle cell anaemia valine is present instead)
How are alleles and genotypes related?
DNA is composed of long strings of nucleic acid sequences, but not all of them code for proteins. The ones that do are called genes. Alleles are different versions of a certain gene. For example, the gene that codes for blood type has 3 different alleles, A, B, and O. The genes that code for hair and eye color also have many different alleles.
What have been present in Earth's living organisms for the least amount of evolutionary time a. photosystems I and II b. genes composed of DNA c. enzymes that catalyze glycolysis?
enzymes that catalyze glycolysis photosystems 1 and 2 cell walls nuclei genes composed of DNA
One difference between a cancer cell and a normal cell is that?
a. cancer cells divide uncontrollably. b. normal cells cannot make copies of DNA. c. cancer cells cannot make copies of DNA. d. normal cells divide uncontrollably. (A) cancer cells divide uncontrollably
What are nonreciprocal crossovers?
Hi I believe you are talking about DNA transfer of genes and I believe it's a transfer of different gene coding which are not Identical. If A is on X chromosome and B is on Y then through recombination A will be on Y and B will be on Y.
What is the use of DNA library?
cDNA is the short form complementary DNA. cDNA libraries are a combination of cloned cDNA fragments. cDNA libraries are used to express eukaryotic genes in prokaryotes.
Result of ab and b parents?
Depends on the B parent. If the genes of the B parent are B and o, then the offspring could have A, B, or AB. If the genes of the B parent are B and B, then the offspring could have AB or B.
What has the author B Berde written?
B. Berde has written: 'Neurohypophysial hormones and similar polypeptides' -- subject(s): Pituitary hormones
What has the author D B Gower written?
D. B Gower has written: 'Steroid hormones' -- subject(s): Steroid hormones
What is the full name for B DNA?
Branched DNA
What blood types can be formed by crossing A genes with B genes?
If the parent's blood type is A and B, respectively, the possible blood type of their child are A, AB, B and O.
Does the entire strand of DNA get transcribed?
No. Cells transcribe one gene at a time.A gene codes for either one polypeptide (one chain of a protein) or for a molecule of RNA. Only about 2% of human DNA consists of genes, so there is a great deal of DNA that is not transcribed.Different genes may be transcribed in different cells, and some genes are only ever transcribed at a particular stage of the life-cycle. The only process that involves the entire genome is called replication and is carried out before cell division.
