Answer 1

Complimentary DNA strand:

T A C C G A C T A A C T

Enzyme involved in adding deoxynucleotides during DNA replication is DNA polymerase.

Three scientists:

Francis Crick, James Watson, Maurice Wilkins.

During transcription mRNA is made

During translation protein is made

Energy source for DNA replication is NTP's and ATP's

Energy source for transcription is ATP

Energy source for translation is ATP

Loaded tRNA brings amino acid sequences to the ribosome.

An alternation of DNA sequence is mutation.

Errors in DNA replication cause mutation.

snRNPs combine with unmodified pre-mRNA to form a spliceosome upon which splicing of pre-mRNA occurs.
