How do stem cells become specialized to absorb nutrients from food as intestinal cells?
by gene removal
by gene activation
by translation
by transcription
Which best describes a strand of DNA?
It is a single-stranded nucleic acid with ribose and uracil
It is a double-stranded nucleic acid with deoxyribose and uracil
It is a single-stranded nucleic acid with deoxyribose and thymine
It is a double- stranded nucleic acid with deoxyribose and thymine
Why is DNA replication considered a semi-conservative process?
RNA will combine with DNA using the base pair rules during this process.
DNA replication must occur before mitosis to produce identical daughter cells.
DNA has two sides of complimentary base pairs held together by weak bonds.
The new DNA molecules contain one strand of the original molecule and one new strand.
Prior to mitosis, a cell will undergo replication to copy the DNA before dividing. Which feature of DNA allows the replication to be semi-conservative and equip the new cell with an exact copy of the genes from the parent cell.
DNA is single stranded
DNA is transcribed into RNA before translation
Hydrogen bonds hold the strands closely together
Base pairing occurs between complimentary strands
What is the DNA compliment for this strand:
ATA CCG TAC ATT GCG GGT ACC
UAU GGC AUG UAA CGC CCA UGG
ATA CCG TAC ATT GCG GGT ACC
TAT GGC ATG TAA CGC CCA TGG
