Which of the following features is common to both dna replication and transcription?
a) deoxyribonucleotides are incorporated into the growing sequence
b) both rna and dna polymerase initiate at promoter sequences
c) both make nucleotide sequences in the 5’ to 3’ direction
d) both rna and dna polymerase require priming

What type of lipids are found in all biological membranes?

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.

What does the positioning of transcription factors determine?
