It is important that a gamete or sex cells have exactly only one set of chromosome because during sexual reproduction two sex cells of the parents will form the zygote and it will have 2n or diploid number of chromosomes. It is from this zygote somatic cells are formed.
The ribosomes on the rough endoplasmic reticulum (RER) most likely produces neuronal special proteins.
Explanation:
Conduction of electrical impulses by action potentials of neurons takes place through controlled flow of charged ions through neuronal membranes. This ion transfer is controlled by specialized neuronal channel proteins which are present in the neuronal cell membrane.
These channel proteins allow for hydrophillic passage of ions and water molecules across the neuronal membranes.
Ribosomes that are attached to the RER are involved in protein synthesis. They carry the code for proteins carried by the mRNA and translate into respective protein.
The RER along with some free ribosomes cluster together as Nissl bodies and are mainly involved in neuronal specialized proteins.
Answer:
a) Pair of restriction enzymes: EcoRI and BamHI
b) The fragment of cDNA that contains YFPH ORF
c) The reverse transcriptase
Explanation:
a) Restriction enzymes are defined as those enzymes that cut DNA. These enzymes recognize a target sequence and cut DNA near those sequences. Choosing these two restriction enzymes allows obtaining a full length protein.
b) An intron is defined as a part of the gene that does not code for any amino acid. The regions in a sequence that are expressed in proteins are called exons because they are expressed, and human genomic DNA has introns, which would not be part of the desired protein.
c) Reverse transcriptase is a DNA polymerase type enzyme, its function is to synthesize double-stranded DNA using single-stranded RNA as a template. This enzyme aids in the formation of the double-stranded DNA when RNA has undergone reverse transcription in the cDNA strand. Reverse transcription means the synthesis of DNA from RNA.
Hemoglobin is a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a heme group.
The answer to this is the bottom right O=O a compound require at least two different elements and there’s only one element in molecular oxygen
